FIC Wiring Help
Today I went to go wire my FIC up, but got kinda confused... This ECM pinout I'm using has got me all sort of confuzzled. Check it out here:
http://www.powerenterpriseusa.net/pr...risControl.pdf Firstly, everything has two different wires listed and I have no idea what the acronyms stand for. So basically, I have no clue which wires I should be using to tap/intercept. It looks like some things are listed as + and -, while others aren't. Here's what I think needs to be done... FIC Power - A21-1 or A21-2 FIC Gnd - C20-104 Injector 1 - C20-108 Injector 2 - C20-107 Injector 3 - C20-106 Injector 4 - C20-105 MAF+ - C20-118 MAF- - C20-116 |

Conn C20.jpg Connectors A21 and C20 are the two ECM connectors. The drawings above are looking into the connectors with them removed from the ECM. What's listed is Function, Connector-Pin The MAF also has polarity listed +/- FIC Power - A21-1 or A21-2 FIC Gnd - C20-104 Injector 1 - C20-108 Injector 2 - C20-107 Injector 3 - C20-106 Injector 4 - C20-105 MAF+ - C20-118 MAF- - C20-116 |

This is what I figured. So I was actually correct?? Two things I don't understand then. What's the difference between +B and +B2 on the power source? And is E01 (C20-45) (injectors) kind of like the ground for all four injectors? |

There's no difference between +B and +B2 (the two pins are connected together inside the ECM). E01 is the common for the injectors.
