Light blue and orange wires

[mmkkpro]

Good morning guys, I am digging into my dash to try to figure out why I have a no start, no dash lights, no warning lights, no horn, no high bean indicator light and no turn signal arrow bulbs flashing. Although all exterior lights work including high beams and turn signals.
Digging around in the wiring on left side bottom of steering wheel I found a light blue and orange wires soldered together and what looks to be a resistor of sorts. It does not look like a factory connection to me. Does anyone know what or where these wires go? I have FSMs but having a hard time reading the electrical one, any help would be greatly appreciated, thanks

I forgot to mention it was wrapped in black electrical tape.

Can you tell us the history of the car and any symptoms leading up to the "no-start? Do you know who did this mod and when?

I have seen dash problems caused by faulty electrical grounds. Inspect for other damaged wires. One over heated wire, due to not being fused properly, can melt the insulation on other wires in other places.

Hi Jim, I bought this car about a month ago, before that as far as I know it sat for 4 or more years. The story I got about the car is the fuel pump went out and it was parked. I'm not convinced of that. I am the 4th owner as far as I can tell. The guy I bought it from is a police officer, he traded a jeep for it 4 years ago to his friend, the friend is the nephew of the guy who bought it new. I have tried to contact original owner with no luck yet, may try to call him today. With the car sitting so long it has really done a number on it. I currently have the whole dash apart cleaning all connectors and searching for why I have nothing when turned to start. The no start along with no dash back lights, no warning lights, no tones, makes me thing I have a short in a major power wire, with that said the fuses have power, auxiliary fuse box has power, all exterior lights work along with interior lights. I tested the started by running a hot wire to purple solenoid wire where the fire wall bulkhead is and it spun over and sounded fine. I have my FSMs and am learning about this car as I go. But as far as knowing for sure the history of the car it's still unknown. This Pic I posted this morning is the only thing I have found to be suspect as far as wiring goes. No other butchering as far as I can tell so far.
Sorry for the long reply, got a lot going on in my head right now. Thank you for your time.

One more thing, I tested my chip in my key its 7500 ohms and treated the wiring coming from switch and it read 7500 same as key so I think vats is OK, still may bypass it, just to eliminate it as a possible issue.

Is it possible the ignition switch at the bottom of the column is faulty?

[mmkkpro]

Yes it is 32valvZ, while I have her apart I'm putting a new one in, I just got my new clutch pedal and bracket installed. Someone pushed so hard on the old one it bent it down and sideways, the clutch master was frozen. I learning this car intimately, that orange and blue wire with that resistor is well done just have not found it I'm the 8a shop manual yet, that thing is kinda hard to read. Thank for the reply.👍👍🏁

Could that be a capacitor? I believe there is a capacitor down around the brake light switch.

What model year is the car.
Can you be more specific about those two wires? Their location and, better yet to what component do they lead?

[mmkkpro]

May be, have not found anything in the FSM that looks like that. It's crimped and soldered very well, but it is wrapped in electrical tape. Not sure what it is, having a time figuring out why I still have no warning or, back lights, no tones for key, lights, seat belts no lcd, I thought sure the new ignition switch would help, gotta keep searching, thanks

Hi, Hib, it's a 1990, the wires are left of steering column and run back into left kick panel area, I found it when I was installing a new clutch pedal and bracket. Have not tried to track down where they go yet. I bought the car about a month ago and this weekend it the most I've been able to work on it. Put a new ignition switch in it yesterday and got it turning over, still have a short in instrument panel, cleaned all grounds, got headlights flipping over in the last hour, still no lcd, warning lights, no back lights, no tones at all and no horns. And although all exterior lights work I have no indicators for turn signals or high beams. The FSM tells me to check certain connectors on ccm and tone generator but they are a beast to get to. To me it seems like I have a main power wire open but I have checked all fuseable links unless I missed one. I got plenty of other things to work on, I am making progress but you know how wiring is, time consuming. Thank you.

OP - check in the FSM 8A-11-5 and 8A-110-0 for possible explanations for capacitor. The crimp is a GM 'splice'. I'd think the value could be found also on the cap. If you just did clutch pedal & bracket etc I'd think 8A-110-0 will explain more likely than the 8A-11-5

Also if you just did a pedal, bracket etc I'd guess that the rod and clip to the clutch pedal safety switch is likely not attached.

See 13, 15 & 19 in this image. You could jumper this and see if you get 'CRANK'

WVZR-1, 8A110-0 looks to be the one! Orange and lt. Blue, that's cool. I'm going back to the introduction of this electrical service manual and study it more, I skimmed over it when I first got them but I can see now I have to understand it better if I'm going to be able to track down these problems. I'm going to start with the horns as it's sorta simple compared to some of the other schematics. I really appreciate your help, thank you very much👍👍

Spend some time in 8A-201- section - that's a components locator that will help you tremendously. Also after each wiring diagram the next page is the component locator and an explanation if there's a 8A-201 image available.

I can't stress how important it is to get a grip on 8A-201.

Horn ain't necessarily 'easy'!!

Is the clutch switch present, connected and operational?

[mmkkpro]

Yes, there is the switch located on the top inside the bracket and another that pushes through the hole in the lower bracket and rests against the small metal tab.
I figured I would start with the horns and work my way to instrument panel warning lights, back lights, indicator lights and lcd display. Then try to figure out why I have no tones at all, I have courtesy lights, all exterior lights, hatch works, windows work, seats work, side mirrors work, I hope the ccm is OK, I guess it controls a lot of what is not working.
