mospin Posted January 11, 2023 Report Share Posted January 11, 2023 1st post off many hope this is okay and the correct place to post this , I have a 620 1974 and I'm currently putting a forged sr20det in place . Currently I'm rebuilding the entire loom for the cab and charge system but I'm hitting problems I have all the service manuals and wiring pdf. But unfortunately the previous owner in Thailand has changed most the wires to random wires which do not match colours on the diagrams so it's now a challenge. Anyway il start with the ones I'm stuck on . I'm currently doing the ignition and I'm left with black with white line does this go into the cam/am box ? With the blue SR coil signal . And I have a black with red line on the diagram it says it goes to the coil also but I'm running SR so do I cap this . Currently I have the white wire now heavy duty red live going to alternator then a 80amp fuse to fuse box and the starter wire signal is black with yellow line . Hope this makes sense Quote Link to comment
banzai510(hainz) Posted January 11, 2023 Report Share Posted January 11, 2023 Icehouse on here would be best to PM I assume you left the orginal wires in the truck then use the engine harness via the can am box to get powered by the orginal harness Quote Link to comment
mospin Posted January 11, 2023 Author Report Share Posted January 11, 2023 Thanks I shoot him a pm . What original wires it was fully butchered and not much left I've ripped it all out and remade a new loom if I knew how to upload pictures I could show you where I'm at Quote Link to comment
