Their harnesses are multi-purpose, at least this one is with TCS, idle stop and anti-dieseling. So for that, lights and/or gauges. I don't know where my anti-dieseling was connected obviously, wasn't connected at the dash panel either, but the wiring inside was loose. Apparently custom means harnesses are made to suit everyone though the package reads "HEI Harness". Other than that their harnesses are built very well, so far.

Doesn't seem right anti-diesel is at the compressor, though the compressor is part of that system. I don't care, it even looks nice loose My old harness didn't have a wire for it. I may shrink wrap the cuts, and I'd like a good tape like they used along the engine. Could put a single connect for temp sender, but the fit is so good as is and not much wire to spare, not sure on that one yet.

Can't wait to see the LH side harness Lost the external regulator but they probably did a twist on that too.

Just to put a twist on it, my harness fits so well, yet here's a pic. of what's supposed to be an in-tact? 402 A/C. There's a wire harness crossing over the intake to probably the sender in the LH head
