openinverter forum

my life was boring, stress and drama free, so I decided to start a side hassle and make and sell custom wire harnesses for EV Conversions, I hope to build this post up over time, so please bare with me

I hope to offer Basic unloomed, partially completed, untested Wire Harnesses for various vehicles with a focus on Sync Serial, Lexus, Toyota, etc. In addition eventually I will offer complete, loomed, and pinned, almost ready to run Wire Harness Kits, where all you have to do is buy your Zombie VCU from Damien Maguire over at EVBM.com and screw it in to the enclosure I plan to provide.

Quality - majority if not all wires, cables, plugs and connectors are used stock OEM automotive quality, I do my best to clean them, but they are not perfect shinny nor brand new

We Are Recycling - 97% of the materials come from OEM vehicles and you are helping to keep these things out of land fills

I may be a lot of things but a business man I am not, however I can not give these away for free, and I have pulled a number of harnesses from different vehicles in the local junk yards, and let me tell you it aint no picnic, that is if you are lucky enuff to have a yard that will allow you to yank your own. Often times it takes visits to two or three different vehicles to source what it takes to make one "complete" wire harness as parts are damaged or missing.

Value Added - in addition to sourcing these parts I plan to add some value by labeling all the individual plugs, cables, and even each wire to show you where it will go and where you need to plug it into. I also intend to disclose where I source the parts from to help and give back to the EV community (did I mention I am not a good business man)

Testing - when selling a partially completed harness I have no way of testing it, sure I can test for continuity but that does not ensure I have pinned it correctly, kapish, so buyer beware, however when offering more complete kits I do plan on bench testing them and even road testing them

SALES: Over FIVE sold !!!!!

Proceeds - I won't lie to you, not all of the money will go to my beer fund some will end up going to our daughters college tuition.

Harness & Kit Prices

$150 - "Shorty" Lexus GS450h/LS600h Wire Harness, identified by the green 3 foot long resolver cables, ideal for bench testing and better than nothing, but may be too short for vehicle implementations

$250 - Lexus GS450h/LS600h Wire Harness (6 foot long gray resolver cables)

$350 - OEM Lexus GS450h Wire Harness (9 foot long black resolver cables)

All Lexus Wire Harnesses Include:

• Inverter Plug

• MG1 Plug

• MG2 Plug

• Shift Lever Position Sensor Plug

• ECT Solenoid Plug

• Oil Pump Controller Power Plug

$150 - "Shawty" Lexus GS450h/LS600h Wire Harness (it's one or the other, as they are pinned differently)

Caution: this harness is short, may serve well as a test bench harness, or feel free to extend the wires yourself, or hewk maybe it will reach just fine depending on your component placement, please be aware the three foot long resolver cables (green ones in the pic) are the limiting factor and dictate the distance between the inverter and the transmission


this one is primarily sourced from the 6th Gen (2007-2011) TOYOTA Camry Hybrid (though I end up pulling from at least two vehicles because one of the already short resolver cables is shorter than the other, so I only only keep the longer ones of the two) sourcing the resolver cables is difficult, sourcing the inverter full length harness is literally hell on wheels, here's a fun video of The Greg in the field:





How do I add value? well aside from getting my hands cut and sliced whilst pulling this junk for you in the snow and rain, I also end up repining the plugs for you as the Camry inverter connector splits the resolvers into their own section in a separate plug and the Lexus combines the two like so.

The transmission side MG1 and MG2 plugs are also different and therefor incompatible so I once again install the proper ones for you.

$250 - Lexus GS450h/LS600h Wire Harness (it's one or the other, as they are pinned differently)





the individual wires in the one pictured below have yet to be labeled

$350 - OEM Lexus GS450h Wire Harness




this one is comprised from two different thinned out Lexus OEM harnesses the super hard to find Engine harness ($450 on eBay plus $35 for shipping) and the Transmission harness ($250 on eBay plus $35 for shipping) to make one EV harness. You are unlikely to find the Engine harness for sale as it is the main huge wire harness that passes through the firewall and the entire car must be stripped out to get it out, hence the high price tag.

This is not my listing, I am just showing you what just the Engine harness goes for on eBay.



In this video I show you how I harvest the Transmission harness from a Lexus GS450h in the junkyard.




and it this long and boring video I show you how I thin out the Lexus GS450h transmission harness to only keep what we need for an EV conversion

here I am thinning out a Lexus GS450h wire harness a customer sent me, this will eventually turn into a Kit for the Zombie VCU


slowly it's getting there, the vision is that you will receive everything except for the ZombieVerter VCU circuit board which you can obtain from EVBMW.com

this will be nicely loomed eventually
Bench Testing...

Good Enuff Quality Control - GEQC

here's the types of things we catch as we use our eyes and hands to see things, can you imagine attempting the world speed record with a damaged ECT Solenoid (E83) wire


and here I caught a severed MTH sync serial shielding ground wire

I appreciate that you are turning your demented obsession with hardness surgery into a service and "business" (we'll call it that when it makes a profit) for other EVers.

The trick will be getting the people who know they need to buy this, to know that you exist, and that they can buy it from you.

and here I am labalizing the sync serial cables


and the Motor Generator plugulators

for the wire harnesses that you will pin yourself I labelize each wire with the corresponding Zombie pin number, labeled ECT Solenoid harness shown below

Great job!!! And fully agreed with MattsAwesomeStuff.

so there I was barely keeping up with the harness back orders, when corporate decided it would be a good idea to offer some items à la carte, such as this handsome 3rd Gen Lexus GS450h Oil Pump Controller Power Harness

On this episode of How To Put Yourself Out of Business, I give away all my secrets on how I harvest all them parts for you

the 4th Generation Nissan Altima 2007-2012 has the same inverter plug as our beloved 3rd gen Lexus 2007-2011 (it is pinned differently but the plastic part be the same, if you follow, the resolvers also live on a separate connector but we'll get to that)

so my day begins at 0800 when Pick N Pull Opens and before I proceed to show you what the vehicle looks like when I find it as opposed to what it looks like 4 hours later when I leave it, let's level set.

Here are the things to keep in mind as you consider pulling these parts yourself, and I have gone through this myself so I am not trying to talk you out of it I just speak from experience.

1. Do you have a junkyard in your area that allows YOU to pull your own parts? Yes or No

2. Do they have the car you need? Yes or No

3. More importantly is the part you need still there, or did someone already pull it, or is it broken? Some yards have an online inventory system but it only shows you when the car arrived and not what's been already sold, this is quite annoying, see my I drove 3 hours for a Lexus inverter, only to find it was no longer there video:



ok on with it, this is what this sexy 2009 Nissan Altima looked like when I found her in the wild, she was 97.2% in tact


one of the first things I like to do is check to see if it has an inverter, and if so if it is a part number that I don't have already, Artur K of the Jaguar XJR EV fame and I are hoping to do some testing of running the much cheaper Altima inverters against the Lexus GS450h gearboxes and dyno test them to see if there is any pony loss or if we can live with it

OK, so you saw what the car looked like when I found it, trust me the engine bay was all stock, and here it is 4 hours later, yes we get to remove the hood, among a million other components that are in the way


yes I had to remove that silly ram horn wrap around plastic intake manifold to get to the main wire harness that runs across the entire firewall (yes to unbolt 4 of the 6 intake manifold bolts blind by feel, Fun Leve: -2)

I call this Civilized Carnage

so if it all goes well we get to yank part of the main wire harness that looks like this, and I say part of it because the way it is routed is completely insane, the inverter lives behind the headlight on the driver side, well this stupid harness runs from the inverter to the firewall than across all the way to the passenger side, yes in front of the firewall in the engine bay, then it goes through the firewall, into the cockpit where it runs back over to the driver side and into some black box module thingie I'm sure, Why? why not just run it from the inverter into the cockpit on the drive side an be done with it?


so all that work for pretty much this, which then has to be cleaned and washed and de pinned and repined, etc.

stole this pic from one of my customer's photo albums, nice to see one of my Lexus LS600h harnesses being put to good use, he is converting a 1976 FJ55

having sold a number of wire harnesses now, I figured might as well finally build myself a prototype, and test one out

here I am fixin' to test a 3rd Gen (2007-2011) Lexus GS450h OEM(ish) harness

working on a custom $350 dollar harness+ for a lad in the UK, he is converting a 1965 Rolls Royce Silver Cloud 3 and wants to retain the original throttle pedal, so in lieu of a throttle pedal and throttle harness I am sending him the oil pump controller harness and pinning the Zombieverter header connector for him and tossing in the enclosure for good measure, he best have some good Chuck Norris jokes on the ready

soon to be another immensely satisfied customer

another option is to yank your own harness(es) and ship them over to The Greg to thin out

here I am about to thin out my very first Lexus LS600h all wheel drive Engine Harness and Transmission Harness that a customer has sent in to Good Enuff Wire Harness Worx

I want to share this process and offer up some tips


Very impressed how he managed to get both harnesses in to this box!

Fun Fact: Wire Harnesses are heavy !!!

so let's start with the Lexus LS600h Engine Wire Harness, cause it just so happens to be on top


So what's the first thing we notice?

here it is nicely spread out so that we can get the lay of the land

and more cut branches

So what exactly do we need out of this so called Engine Harness?


Well, this! The Inverter plug and the tail that comes out of it.


We don't need this white plug below, I just pulled it as a home run for completeness to show where the other ends of the sync serial cables from the inverter plug terminate

so this is what we need, note the two Resolver Cables have been cut prematurely, both of them should run to a single white plug which then accepts the resolver cables from the gearbox

and here's a fun little Stare 'n' Compare of what we need and what's left over

The Lexus LS600h transmission harness was up next


this one was beautifully extracted without any severed limbs

if you spy one of these on eBay here's how to ensure you are getting the proper harness as technically this is not called Transmission Harness but Engine Harness in the Lexus Manual, [not to be confused with the actual Engine Harness which Lexus calls Engine Room Harness] so look for this plastic S shaped housing that hugs the gearbox

shown hugging the GS450h gearbox, but you get the idea


and the obvious MG1 and MG2 gray resolver plugs/connectors

and these are the resolver cables extracted from the Transmission harness


and here's that white connector that runs to the matching white connected on the Inverter harness (that our inadvertently customer lopped off above)

but we were not done yet, there are still two more connectors to yank out, the Shift Lever Position Sensor connector (to send the Drive and Reverse signals to the VCU, etc) and the ECT Solenoid connector (to shift between High and Low gears) [optional]
