Hi everyone it's been awhile since I've been on the site, but I just started working on my 72 Chevelle again and ran into a question. I'm trying to clean up some of the engine bay wires and I was just wondering what the object in the picture is? I would greatly appreciate the help and thank God for this site =]
It looks like a relay, but not really sure which one, too many wires for horn
Thanks for the suggestion, it's up by the wiper motor area. Hope some more people can help out.
One way to find out quickly is to disconect one of the wires and see what doesn't work. Horn, headlites, wipers etc.
You could just start tracing some of those wires too , and see where they go too
Thanks guys for all the suggestions, also if anybody has a wiring diagram for a 72 Chevelle I would really appreciate it if you could post it up. I bought a wiring diagram for my car off eBay but it has all these old diagrams and isn't really helping.
Thanks DennyW for the help, you've always helped me out on my topics. I'll see if I can trace the wire from the horn to it.
Another question I had, was I was looking at the wiring diagram from the book that I have, and in it it mentions a TCS SOL and the IDLE STOP, the motor that's in the car right is not the original motor and I think these parts are missing therefore these wires are just hanging out in the engine bay. Can I cut these wires or what should I do about them?
I posted some pics of the book that I have on the wiring for the car.
Thanks again DennyW for all the help and suggestions.
the tcs is transmission controlled spark its a nox device retards the timing in the lower gears to reduce oxides of nitrogen (nox) they also had an electric idle solenoid it was a stepper motor when the it poped out and you would adj. the idle with it that was so they could run a vary lean idle they used what is called the lean idle rpm drop method of adj. the idle d.i.y. er mechanic did not understand the sys.so the unplugged the wire and set the idle so on a hot day they couldn't under stand why when they went to the store turned the ign of went in and came out with a six pack they thought the motor was running backwards but it was actually dieseling thoes were the not so good old days of primitive pollution devices and sealed idle mixture screws believe me you don't want either of those devices .......ted
Wow thanks a lot Ted for the info, I really appreciated it.
Everyone the component turned out to be the horn relay, just want to thank everyone for the help and suggestions on my questions.
Hey guys I have another question, I'm working on the car right now and noticed that the wire coming from the distributor was just twisted with another wiring coming out of the firewall. I outlined the wire in the picture. I was just wondering what would be the correct way to connect the wire to the electrical system.
Bump. Hey guys just wondering if anybody could help me out with that last question, any help would be greatly appreciated.
if I had to make a guess when somebody took the point dist out and put the h.e.i. in they needed a keyed 12v. supply because the original wire was a niachrome resister wire so they took it off the wiper motor because its hot when the key is on. the wiper switch turns the ground of and on in g.m. if it was my car I would run a 12 or 14 gage wire from the ign sw. to the h.e.i. but that's just my opinion and I could be wrong and frequently am just ask my wife she'll tell you......ted:LOL::LOL:
Thanks DennyW and Ted, I really appreciate the help guys.
Well just wanted to thank everyone for helping me again, I got the car running today and man did it feel good to hear it running.
