Trying to sort a rats nest.

[83Burban]

My 83 K10 is now a 454 w/ NV4500 combo. Having some wiring issue now. Due to the Frankenstein nature of this rig and previous molestation from the previous owner.....Having a hard time based off stock diagrams and Google searches.

Took this photo 2ish years ago when I started the swap. This was after deleting the AMP they stuffed in the dash. I cut a lot of this out.

This is where I am today. Wires running out the door im 99.9% sure are stereo related.

My cluster is all working. Headlights and tail lights are working.

I have no brake lights. Or turn signals (they are shorted somewhere and blow the fuse immediately).

Google says I'm looking for a switch with an Orange and White wire. The only pedal switch I can find is this guy.

It has a Pink (w/ black stripe) and Purple wire. Depressing this switch does nothing. Thought it might be some form of ignition safety switch, but I can still start with or with out it depressed.

there is this connector....it's close to the new break pedal switch location. So maybe I need a different switch?

there is also this colorful guy back up under the dash with no mate that I can find.

Non cruise uses orange and white, cruise equipped uses Grey.

That should go to the pigtail on the column for the cruise buttons, if it still has a cruise stalk on it. The mating plug is a flat piece of circuit board.

Here is a link to the 1983 wiring diagrams

Aside from the column. There really are not any cruise control components left in this truck. But just to clarify. You do think that plug with Grey wires is for the brake light switch? Trying to find my old pedal assembly to check and see if a switch got left on it

Tracked down my old pedal assembly. Sure enough it has some switches on it. Assuming the white one is for cruise control as it has a vacuum port on it. But my issue now is that it would appear as though I needed two connectors for the break switch. But....I don't seem to have two loose connectors hanging.

the vacuum hose goes to the cruise servo. It’s a backup, if you hit the brakes and the cruise doesn’t electrically disengage, the vaccum switches dumps the vacuum and the servo releases the throttle.

That connector is where the pink/purple wire plugs in.

Lol why would they have a random switch plugged into the pink / purple connector?

I think there are a couple of things going on...the cruise vacuum switch in your picture might be a replacement, as I don't think the original also had an electrical connection.

The brake switch with the two connector points would be original for cruise truck. One set of contacts is for the grey/grey-blk connector that would kill the cruise when brake pedal is pressed. The other is for the missing org/wht wire connector that controlled the brake lights for all (cruise/non-cruise) trucks.

So....in case you were wondering. I found the original brake switch connector with proper orange/white wires. When they put the column back in it got pinched up above it. Thankfully was not damaged. So now I have brake lights again. The position of the brake pedal makes it too short to reach the switch. So magnets for the win.

The roads I run on sometimes would knock those magnets off in short order. I would be trying to drill and tap for a ¼" bolt secured with a couple nuts using the bolt head as the switch press pad. But if it works....
