Question need help,where does this wire go?

i swaped the dash on my car and i accidently cut a wire for the microtech. i have two pink wires coming into the drivers footwell area. one goes to the fuel pump relay and i assume the other goes to a 12v ignition source but i lost the wiring diagrams that came with my lt10 unit. all i can find online is the diagram for a lt8 unit and that diagram only shows one pink wire that looks like your supose to run to the fuel pump relay and slice into that and run it to a 12v ign source.

is this extra pink wire the one that has to go to a 12v ign that dosent cut power when cranking the engine? can someone please find me a lt10 diagram? thanks

The 2 pink wires you had are originally spliced. Thats how they come when you buy a brand new microtech loom.

The Pink wire feeds the trigger pin for the fuel pump relay(can be pin 85 or 86), it also needs to be fed 12v ignition(that needs to stay on while cranking, get this from your ignition barrel, IG1), and your computer needs to be fed 12v ignition via the pink wire.

What microtech do is have one pink wire coming out of the microtech, that splices in to two, one that goes to barrel and one that goes to fuel pump so this will feed both pump and microtech.

I hope that makes sense.

Ok my Link was bad >>THIS<< is the right one.
These diagrams where made by Chis and me, because we had also some problems with the originals.
If you download the first diagram you can see by full-size at the pin 1 a "P" for pink.
