Wiring Diagrams

 

These are specifically drawn for the configuration that I sell the ECU's and wiring harness.

Ammendments to wiring looms:

February 2008:
On 1 and 2 spark output ECU's Spark A = 0.75-1.0mm Yellow cable, Spark B is a 0.75mm-1.0mm Blue cable. Previous looms had Spark A = 0.5mm Yellow, Spark B = 0.5mm Blue/Grey. The Blue/Grey cable is now used for IAC2A Stepper output on MS2 ECUs. Previous customers wishing to have their coloured loom changed to this please e-mail me and I will do it free of charge.

August 2007:
The screened lead for the trigger signal (VR/Hall/Points, etc) can vary. Some may have a blue cable some have a black cable inside it for the ground, the red cable is in both types and is the signal input.

June 2007:
Wiring looms have changed to coloured wires. For older looms (black wire with numbers on them) see HERE.
