Help bare wires

[93GASE3300]

I have a light brown wire in the vacinity of the battery that is bare and I have no clue what it is for. There is also a red wire that is bare near the "twist and pull" connecter on the left front fender. It doesnt go to the connecter but it looks like it may have gone there. If anyone knows the purpose of these wires please tell me. Those damn chiltons books are crap. I would do anything for a real service manual.

Thanks guys

It may be to your horn. Does your horn still work?

Maybe the fogs lights? I had this red wire coming off the positive battery post and another unconnected red wire nearby coming out of a harness. I played with them but never saw any current going thru them. Then I noticed the fogs were out and when I cracked the service manual I found out the wire on the battery has a fusible link in it and it is connected via the red wire in the harness to the fog light relay which was working. At first connecting it back up I still couldn't get the fogs to fire, but discovered that the wire in the harness was kind of touchy and managed to lock it in a position where it conducts properly. Eventually I'm gonna try and cut the touchy piece of wire out and solder and tape the wiring properly.

BTW, FWIW, I don't think this is an engine specific issue.

Also, I think the wire near the twist connector is a test wire..

No actually my horn doesnt work and neither do my foglamps but the bulbs are blown to them. Where does the light brown wire go to? Does it connect to another wire some where or something?

[DKOnLine]

Check and see if your car actually has the horn on it. If it does I would look there and or find the wiring Diagram. I am pretty sure that the brown wire goes to the horn. I had the same brown wire on my Cutlass Ciera with the 3300 and I had to hook my alarm to it.

[93GASE3300]

i know that the horn is behind the bumper and there is a connector on it but if the brown wire is in the circuit it may not make the horn work. I have a haynes manual and they dont exactly give you very specific wiring diagrams like that. Ill check into it unless you know where i can get a diagram. Thanks alot for the help I really appreciate it.

[DKOnLine]

Yeah I looked in the Haynes manual too and didn't see anything. Maybe Shawn or Kelly can find a diagram. Try sending them a PM. Or see if they can move this Subject over into the Problems and Solutions.

I have a '92 shop manual at home, I'll try and look up the horn wiring and post up later...

[93GASE3300]

thanx alot largefish. Where are you gonna post it so I can check it out?

[LargeFish]

Umm well I won't be home until after a HS FB game tonight, two of our kids march in the band. So late tonite or sometime this weekend I guess...

[93GASE3300]

K ill check it out later, thanks a lot for your help and good luck with the football game.

OK, first I'm really not sure what you mean by "bare" - if it's just insulation stripped off, fix it with electrical tape. I was thinking you meant unconnected earlier. No such thing as Lt. Brown in the GM books. Brown and Tan. None of either color in the horn circuit. Tan is probably what you mean and it's used going to the low beams. There are brown wires going to the signals and markers in front.

[93GASE3300]

very strange, it is cut completely and stripped at the end however the headlights work and so do the side markers. The wire is tan is there any other circuit it could be part of? I looked at it earlier and it is part of a connector that branches off down near the side cover of the tranny. But like I said it is cut near the battery and stripped at the end like you would do for a speaker wire.

[LargeFish]

There is a tan and black wire used in the TCC circuit, maybe that's it? Hard to look thru hundreds of pages of diagrams. Only other tan wires I noticed in a cursory scan were grounds from the ECM and one of the front speakers. Does it look like stock wiring? Maybe somebody's mod/hack job...

[93GASE3300]

definately stock wiring. the things that dont work in the car are the horn, and the dome lights and buzzer stay on with the doors closed but im pretty sure thats because i need new door lock actuators. If that wire isnt in the horn wiring diagram perhaps I have quite a dilemma. Ill look more at the wiring tommorrow and see if I can get more details for you so we can narrow it down a bit. Thanks again for your help I really appreciate it

[LargeFish]

A lot of folks disconnect the TCC - the wire is solid tan, not tan w/ black stripes, right? Hitting the rack...

[93GASE3300]

im not sure where the wires go after the connector but I just replaced the tcc solenoid because it stalled on me after i came to a stop light after getting off the highway and I was told it was common with the 3t40 transmission. There is two wires after the connector and two wires before the one that is cut is before Im not sure if they are all tan or not but im pretty sure the two wires before the connector are.

[93GASE3300]

Ok heres the deal. I took out the battery to get a better look. What I see is a 8 maybe 10 gauge red wire coming from B+, the red wire is a fusible link. After the red part of the wire stops there is the core of the fusible link and then it splits into two tannish maybe 16 guage wires one of those wires goes into a connector and then dissappears into a large harness down near the tranny, it doesnt go to the tcc. The wire I need to find out what it is is the second wire coming off the fusible link. I hope this will narrow things down a bit. Let me know what you find out.

[LargeFish]

Hmm, I looked at the power distribution diagrams carefully first and there were no Tan wires whatsoever. Unless they changed some colors between 92 and 93? I'll check again tonight...

[graden]

k i just finished wireing up a 3300. the brown 1s are suppost to go to a ground strap located on you tranny bell housing. the red 1 is suppost to go to your starter on the main bolt. now remeber my engine is from a cutlass. but i almost sure its the same color wireing harness. this is where i think you should start looking.

[93GASE3300]

the wires that are tannish are part of a fusible link so if someone with a manual can find a fusible link that is in the vacinity of my wire than you can probrably find out what it goes to. I wish I could find a service manual Ive been looking for about two weeks on e-bay and I can only find stupid haynes manuals. Oh well thanks for everone helping me I appreciate it greatly

[LargeFish]

OK, I think I saw some fusible links that were rust and also there was I think some orange wiring in the power distribtuion diagram. Let me know whether or not you have DRLs as some things are different for a VIN N with DRLs. One other thought: some larger libarary branches have shop manuals in the reference section...

[93GASE3300]

thanks for the headsup on the library thing ill check it out. As for DRL im not sure whether it has them or not. Ill check into it and write it later. Thanks for your help.

[93GASE3300]

Nope I dont have DRL's and my local library and every other one within a 100 mile radius has a shop manual for my car, worth a shot though.

[93GASE3300]

Yeah but my car has a red fusible link that branchs into two tannish wires.
