I think this is more of a deal with the V8 than the AMC 258 i6 / 4.2l .

LG, I luckily don't have to deal with SMOG. So no worries there. I am purchasing a spare GM module and coil to keep in the Jeep. I have some history with hei's and had modules fail on me. There is abdolutely nothing you can do except replace them and when they go, they just go no warning.
The only complaint on the wires are the fit at the cap, and very well could be the male tips on the cap and not the wires. But a pair of pliers fixed that issue for now.
All in all, the conversion went great. Gave me a reason to pull the wiring harness in the engine bay apart and inspect. Put it back in a new loom. All looked good. I did fined my main power wire from my alternator had a compromised wire. It was pretty bad but had I not done the conversion, it would have eventually failed on me. It's fixed now. Used weather proof butt connectors throuout also.

Yeah, just cause it's new doesn't mean it works. Seen that also.
