What do I do with this wiring?

I can look up some info on alldata for you.

What model did this motor come from? What is the 8th vin number from donor vehicle?

Thanks brother, I appreciate your help. Here is the printout from the donor.

Generator battery control module. That is what is around the negative battery cable.

It's a module of some sort with a 10 pin connector



The numbers on the top of the module read 15137027

The bottom reads RVGB 621375

Scroll all the way to the bottom and look at pin 74 and the green box. Need to do more digging on deleting it and possibly tuning out the DTC code for it if you get rid of the module.

I dont think those 2 wires are for that module. They are not even in the diagram.

I dont know why it is so small and wont let you enlarge it when clicked on. I hate the new photobucket.

My pin 74 is there along with 75. It's hard to read that block. Not sure what to do with it, the guide says rewire alternator gray here which is already there on my C2. I think that the diagram on lt1swap is talking about pin 75 on that. It's in a weird excel format. When I copy and pasted it to excel, it reads like this

Im just surprised that there isnt a whole lot of info on this as there are plenty of people using these later year motors.

To me it just seems you would take the gray wire coming from the alt and wire it directly to the ECU and the brown wire on alt to your charge indicator in the cluster.

Im just glad mine didnt have all that.
