Electrical Connection
Input signals, start and stop conditions described in S40 service manual[2]
The harness for the motor supply can be bought completely (Part Number: 30775461 [3]) or just the connector. There is connector kits available online (avoid the pig-tail version as the cable is way undersized. Link)
| Pin Number | Cable Color | Function | Comment |
|---|---|---|---|
| 1 | Red | Permanent +12V for Motor | Fused with 80A fuse (F2) |
| 2 | Black | GND | |
| Pin Number | Cable Color | Function | Comment |
|---|---|---|---|
| 1 | Grey-Blue | Ignition +12V for Control | Fused with 10A fuse (F53) |
| 2 | CAN-?? | ||
| 3 | CAN-?? |
A visual guide of the pinout can be found on this MaxxECU online help page
CAN Bus Control
The CAN bus protocol has been reverse engineered in the rus EFI forum[7] and a LUA script example exists[8]
Additionally an implementation using arduino code[9]
Mechanical Dimensions
- fittings and sizes
- Pressure side (to power steering pump) M16x1,5 (you can use adapters like this one: https://www.ebay.de/itm/192079081475)
- Low pressure side is just a hose
