Clearly I wasn't thinking....i know.

I was drilling a hole through the firewall of my 92 to put in an aftermarket temp gauge. While wallowing out the hole with the drill, the drill bit grabbed some wires and ripped them up. It looks like 2 wires were tore completely apart (good sized piece pulled out) and at least a few more were damaged. These were all part of a single thick bundle just above the steering column under the dash.

Here's the thing, nothing has changed. Everything in the truck still works.

All these snowflakes in your comments acting like you’ve got some big emergency, lmao.

Best truck I ever owned was my ‘56 Chevy. Maybe two dozen wires, total, on the entire truck. It ran incredibly well.

My advice is to get under there w some tin snips and clear all that excess junk out of the way.

If you insist on modern gimmicks like electronic ignition and a fuel pump, the wiring diagrams are all online— I’d find out what those wires are you damaged before doing anything.

I did just rewire my 89, and there are some unused wires under there, so there’s a small chance you got lucky.

Or, it could be for something more subtle, like a sensor or something that could cause delayed onset problems.

It’s relatively easy to get up under there if you pop off the panel just beneath the steering wheel, then carefully cut through the bundled loom.

You can really get access if you loosen the steering column — it’s only four nuts and a plate if memory serves. It drops down and you can clearly see the entire loom.

Depending on what you need to get at, that may be a timesaver in the long run.

Could you be more specific? Actually you can’t because he really just got sound advice. And your advice of comparing his 400 to a 56 Chevy and hacking out all the wiring is just dumb.

The angled plug holds your turn signal flasher can. The solid wire twisted together in the background is a fire hazard. Remove the solid core wire and replace it with stranded wire and good connectors. Then find whomever dorked up that wiring and give them a solid kick in the jimmies.
