  • factory ecu and wiring for 3.4 DOHC

    Well I got a factory ECU and complete wiring haRNESS OUT OF A DONOR CAR for my buggy project. Does anybody know what sensors I actualy need to make it run right. Does anybody have a wiring diagram or pin out for the 3.4 DOHC.

      I don't know the exact year but I think from looking at some diagrams I think the harness is a 92. What I need to know is what the wires do that go into the firewall on the passenger side of the engine compartment. I have pretty much the whole harness figured out, I just need to know what the big plug into the firewall does, and there is one more plug with like 6-8 wires on it that goes over by the driver side firewall.
