have 84' c10, appears it had smog/emissions on it at some point. Has the ECM up behind glove box. Now it has NONE of that on it, it is a carb motor. I have looked tirelessly on the web and can't seem to find a really good wiring diagram. I want to go over the entire harness and make sure it is good to go, as there are a couple random wires cut. I want to know and make sure i can eliminate the ECM completely since NO smog or emissions control.

The ecm is just for the electronic spark. I removed mine and installed a regular hei distributor. I later did a carb swap and removed a lot of the other emissions items. Then later came an engine swap and I didn't want to look at the extra wires anymore. All I did was strip the entire harness down, remove the connectors and wires that were no longer in use, then clean and/or repair anything else. Once that was done, I routed everything where I wanted it, then taped it up in groups that ran together, and put those groups into the proper size of the black corrugated tubing.
