Today I went to go wire the 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

The thing is, even for the injectors, C20-45 is listed next to all of them and I don't understand why? Enlighten me pleeeease. In the mean time, I need a beer.

... and aloe.
