1979 Caprice wiring harness

Does anyone know if the 1979 Caprice under hood wiring harness is available anywhere?

What with it being 37 years old, a replacement would be nice and trouble free.

That heat and open air plays he** on the wiring.

I checked in at RockAuto. No deal on a whole harness.

There must be something out there?

Welp unfortunately there isnt anything unless your wanting to replace the entire wiring harness through out the car and at that point id get a painless wiring harness. But about two months ago i had a starting and charging issue, found out it was one of the wires that went to the starter that also connected the battery and rest of the entire cars power supply. So i went and bought about 10 feet of 8 gauge and 10 feet of 10 gauge. So i replacedmost of the wiring in between the battery, to the starter, to the alternator, and all the way to the fuse box were i spliced it in, Also changed the battery cables since i was there. I had also upgraded to a 108 amp alternator and i think the factory size was a 10 gauge, didnt have any issues with it but for safety i replaced it with 8 gauge. Since i upgraded the alternator and was upgrading the wiring, i also added a 150 amp mega fuse inline from the battery to the rest of the car. Then i wrapped some of the wiring in heat shield since those starter wires are so close to the headers. The wiring harness is pretty simple well i mean it was for me, just replaced one wire at a time. And now no more issues with starting and charging!

Thanks for the information and guide.

I may just go and do that with the wires.

I have a 105 amp alternator on order.  So maybe go with the #8 wire right up front.

What is the 150 amp Mega fuse?  Whats up with that?

Inform me for my assurance to not burn the car down.  

Haha i just added it to protect the battery from rest of the car, its not needed but most cars today have them, so i decided too also. Mine looks like this

Is that something to get through Ebay?

I like the idea.

Oh yeah definitely, i bought mine at oriellys, they didnt have them on the shelf they were behind the counter, but you can get them at the other local auto parts stores im sure.

Thanks. I will check it out.

well let me rephrase that, the holder was behind the counter but the replacement mega fuses were out on the shelf, youll need a holder!

No problem!
