Running lights not working

[TPCLARK]

What’s up CK5! I’m working on my 90 blazer and I cannot get the running lights to work. I’ve found one spot along the orange power wire that was corroded through. Fixed it with a crimp but ids still not going. Is there a way for me to fix this issue without pulling the whole harness out? Are there replacement harnesses out there?

You check the fuse ?

Isn’t orange for the interior lights?

Found that the turn b/u fuse was out, that got my turn and reverse lights back, still no running lights or brake lights.

on a gas engine 90, the fuse (t/l ctsy) fuse is powered up by a fuse link off the back of the alternator. It then goes thru the fuse, to the headlight switch, then out to the lights.

Stop/Hazard fuse powers the brake lights. Goes from the fuse, to the brake light switch, out of the brake light switch, into the turn signal switch, and out of the turn signal switch, to the brake lights.

I’m not sure at this point because it runs all the way to the rear lights

All rear tail lights should be a brown wire.

The headlamp switch provides power to the running tail lamp fuse.

The headlamp switch provides power to the running tail lamp fuse.

Not on a 1990 R V series. The fuse comes before the headlight switch. The dome lights, and the tail lights are on the same fuse, which has full time power on it.

Hmm well I'll take your word for it. Trying to remember how every fuse is powered from way back is fuzzey

Stop/Hazard fuse powers the brake lights. Goes from the fuse, to the brake light switch, out of the brake light switch, into the turn signal switch, and out of the turn signal switch, to the brake lights.

Awesome I’ll check this out. Any knowledge on where the running lights are at?

All rear tail lights should be a brown wire.

my headlight switch has a brown wire with a connector on it but I can’t find anything for it to plug into. Have you seen this?

That maybe an aux tap for options like cab lights etc

Thank all of you for helping out! I ended up finding a cut wire and replaced the back of the harness with some trailer wire. All my lights work now!
