Thoughts, comments, advice...
1971 C10 w350
Picked it up with broken neon tube lights, trailer brake control, (keeping?) Boomer stereo and related, aftermarket A R A cruise control with broken switch in signal arm. Have new non cruise lever and stop light. Other that following the wiring and disconnecting it is there anything I need to be aware of?. Never reverse engineered one of these things. Battery neg is disconnected. Would prefer not to toast the rest of it when I hit the key
Wires were all twist connected and wrapped with painter's tape or scotch locked
Thanks!
MC

Just disconnect the power and the ground, that should solve the toast problem. Some of those had a sensor of some sort on the drive shaft, look for that and follow wires back to the unit under the dash. I would assume the wireing to the blinker handle would have a connection on it. disconnect and you should be done.

I see a mess like that, I just start pulling wires and start over. But, that's just me.

That is not just you, brother.
At issue for me is, how am I going to feel when, down the road, I have a mysterious electrical issue. That Extra Spicy Ragu mess in the way will likely cause an embarrassing public display not suitable for women, children, pets, and some men.

The wires change colors, sometimes three times to different splices. The purple from the ignition switch is cut n spliced twice. One to a pigtail that goes to what looks like an aftermarket relay that goes into the column( with four other wires spliced into who knows so far then to fuse box, one connected to the tach wire and another spliced into the HEI.
I need a drink or two...I'm afraid of I remove all this mess someting..or nothing will work

Ok boys n girls...arrgg!
Cut the wires a few inches back from the splices. Didn't get into them at all. Ignition is hot, Burped the switch and all good. BUT I Have no lights but the cab light, no gauges, no blower nothing....
Fuses good, nothing smoked...
I'm going to have those drinks now! Should I start smoking? Already hot under the collar. WTH?

52Carl this mess started as a foot stuck into the wiring hanging down above the brake pedal. Oh the pain! Why o why?

You know what needs to be done, Mac.
A beer is definitely called for.

So worst case scenario...if I can't get this mess straightened out, any suggestion for a new wiring harness? As in stock(ish), 350, tilt wheel, AC harness? Fuse block is good. Or should I just require every thing individually? Experts? Anyone? Whits end here...nothing I have found online yet makes me jump for joy.

Three fingers n two ice cubes going on!

With any luck you should be able to tell which wires are original and remove the wires which do not appear to be original. If not, I would replace all of the wires with a new harness.
