every thing needs a good ground and old worn bulb sockets can do funny things , I'd find a manual with the diagrams , once they go through the firewall they go in all kinds of un known directions , when doing auto electric I get schooled about every time , why did they melt ?

sorry poor description they put a bigger fuse in the #10 so it fried the engine harness so i rewired the whole thing with no harness connectors but i dont know the colors of tailights and left blinker and theyre not working ive got the chiltons but im no expert

well ill do my best ive heard of running a wire from the fuse block to the tailight harness i dont know ill just have to see im trying the justanswer website right now ill see how that works


Take your time , the thing about "running the wire " is that they've already done that , Use a jumper wire and a multi tester to see if there's shorts or continuity .the brake light may go through the directional switch .


ever done any house wiring ?

that website was a load o crap thanks for taking the time sir but I literally had the wire harness connector melt down and had to bypass the whole connector now there is just a continuous stream of wire and there is no way of telling me which wire is which as far as multi tester jumper wire you might as well be talking a foreign language absolutely and utterly no idea how to what Id like to do is upload a photo off the chiltons and see if you could tell me what color goes to where off that engine harness mess


if you could get the firewall disconnect from a salvage yard that might help you I'm not sure , the wires can change colors once they go through the wall , it's a complicated job , I'd probably be pulling my hair out , I can't find good wiring diagrams on line either , do chiltons even have them ? A haynes manual would , I'll see what I've got lying around may be that would help


the directional switch may have got fired , if you can take a look at it and see if it's toasted


I found diagrams for the buick regal and other GM cars , you won't be able to read them if I post them they're small print and complicated but like I said the brake light goes through the directional switch , if you could ask a specific question I'll take a look and try to help , I mean without an electrical understanding this may be difficult

hey thanks for the reply im not sure but my brake lights work just not the taillights and left blinker I have the book but i dont know how to read it like i said i could take a picture of the books diagram and we take a look if that sounds possible

also some sort of switch could be possible because now my fuse is popping so pretty sure i got a short
