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)

Connector A[4], Part Number: 31266849[5](not verified)
Pin Number Cable Color Function Comment
1 Red Permanent +12V for Motor Fused with 80A fuse (F2)
2 Black GND
Connector B[4], Part Number: 31346135[6](not verified)
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 RusEFI forum[7] and a LUA script example exists[8]

Alternatively, there is an implementation using Arduino code[9]

Mechanical Properties

Dimensions

Approx. 12" x 7" x 7" (305mm x 178mm x 178mm)

Fittings

  • High pressure side (pump supply/outlet): M16x1.5 (you can use adapters like this one: https://www.ebay.de/itm/192079081475)
  • Low pressure side (pump return/inlet) is just a hose. The fitting on the reservoir is likely 10mm (3/8").

Mounting Bracket

WillFab Motorsport (WFM) produces a universal fit bracket for this pump. Available here and here.
