well rats chewed up the stock harness and my megasquirt came with harnesses so i just ran new engine management wiring off the ms3x harnesses. then rats came through again!!! after i patched the holes in my garage (apartment garages with shared walls) them little suckers got my wideband harness, ign wiring, and some fuel wiring. repaired it all. going to head to a junk yard whenever an mx6 shows up and buy the wiring harness and adapt to that for a cleaner harness. im no where near professional level so its roadkill but eventually ill sit through a proper wiring harness youtube lesson and use fancy connectors.
