I have removed the hot wire wiring for the fuel pump from the harness of my donor car (which had a 3800 swap). The connector to the fuel pump is 4 pin where my stock 88 connector is 3 pin. Here is a picture of what it looks like...



The two wires on the far right went to the harness. Here is my stock plug.



My question is whether or not anyone knows how I should splice the two wires into my harness which has three wires?

I would just redo it all together that looks sloppy.. But if you must use it then maybe just find a connector pigtail and resplice it, from the looks of the picture the extra pin just seems to be a spare ground.

Pink = gauge
Tan = output (Relay 87)
Black = Ground
Relay 30 = Fused HOT
Relay 85 = Ground
Relay 86 = PCM C2-3

Glad this thread came up as I wanna add this since my swap is out. I am using Darths page to wire it up but dont understand step 8. Can someone explain this to me...

Someone could correct me if I'm wrong but I think what he means is to change the wiring so the PCM relay output routes directly to the relay, rather than through the oil pressure sender first.. That step is for stock conversion not for 3800 swap where you redo it all anyway.

Ok...so I dont need step 8 since I am swapped. That is what I was thinking but electrical is my weak point. Thanks

Electrical isn't my strong suit either, where can I find the relay port numbers? How do I know what wire PCM C2-3 is? I won't be able to work on it until this weekend so I may have more questions later...
