Hey all, I've got a 91 GT hatch w/3sgte swapped in. Everything is beautiful, harness looks great, etc. My only problem is the 3rd ecu plug integration, the 14-pin 5sfe to 22-pin 3sgte. I don't have any idea what goes where, or how to splice them. I've been in contact with phoenix tuning (tweakd performance) for weeks, they (cam) was supposed to send me a diagram on exactly what wires go where, but I've gotten nothing. I need to know how to wire this, as its all I need to be up and running. I've gone over the pinouts countless times, and still don't know. Do I match +b to +b, els to els, etc? I know something has to be tee'd into the circuit opening relay, but what, starter wire? this is a fairly popular swap, someones gotta be able to help. Thanks in advance.

Are their only 13 wires that are used on that 22-Plug?
SPD = Speed sensor from transmission hook it up to the old wire that says SPD B and B1 = are from the EFI main relay. Batt = 12v+ hooked to 15A fuse. AC1 and ABS can be left out if you don't have ABS or aren't planning to use A/C system. W is for check engine light. FPR on the 3sgte can be left out, but you would have to check and see if your fuel pump is running wen your cranking. I don't know which wiring your using nor if you spliced the 3sgte into the 5sfe a little more detail would be nice |
