1986 C10 wiring
this has probably been covered. I'm restoring a 86 C10. Need to know what I need to use to keep the cruise and a/c. I'm going BBC so ECM will be tossed. Trans will be turbo 400. There is a ton of switches and boxes under the dash. Unfortunately I did not strip this down. So what can I toss. Has dual tanks, A/C, Cruise Gauges, and power locks. Thanks in advance....I know some one has done this just want to clean up the wiring.

The ECM only controls the carb IIRC. I tossed mine.

Re: 1986 C10 wiring
There is a little blue box with three wires going to the optic eye in the Speedo. Keep that if you want cruise to work.
