Re: ClusterTruck; because that’s what it is
Now time to start the wiring. I'm wanting to keep this easy to service, so the harness and fuse box needs to be a unit. I want it easy to remove when pulling the engine, like stock. Lay it over the top of the intake and go.
My previous EFI swaps have been TBI. Those were easy to disconnect on the engine side. The LS setup is not. For me, that means that any circuits not run thru the fuse/relay box need to have a connector so they can be unplugged. The fuse/relay box has the switched ignition relays and fuses (pink wires) for the PCM, injectors, coils, and sensors. It has the fuel pump relay/fuse and the AC clutch relay/fuse. And last, the constant power (orange wires) for the PCM. I'm using the factory C100 connector. That one has the cruise switches, serial data to OBD connector, Check Engine light, RPM, and a couple others that may be useful. That leaves me to make some connectors: 1-pin To the fuel pump 2-pin Hi/Lo fan relay triggers 3-pin at the 68 harness Temp sender Starter solenoid Coil power, now used to turn on the pink wire circuits 4-pin for PCM signals, to go to the interior Brake switch to TAC Brake switch to PCM Clutch switch Shift light. **It's in the manual trans diagrams, maybe it'll work, maybe not. I've used it in TBI so it's worth a shot**
