Wiring Harness ID

[Tiv]

Hi all,

Nooby member here
Just invested in a new project, my first Chevy, and struggling to ID the wiring harness, I think it might be from a NOVA, as the steering and front clip is from a NOVA, can you help? Is it and if so what age?
Ive trawled and dug out various wiring diagrams of the net and some bits of the ones Ive found match up with the wiring (lights mainly) but the rest of it has discrepancies. None of the wiring diagrams Ive found identify what the fuse layout is and most of them only show one flasher....
....confused.... in need of help....
I can redesignate and rewire to suit my needs if I must being from an electrical background, but trying to save some time....

Oh and Ive no idea how to attach pics?? Sorry to be a novice at this forum lark.

Thanks in advance.

That looks like one of the aftermarket ones, mine looks similar (American autowire) but it's not exactly that one, maybe an ez, painless etc

Looks about like my EZ Wire fuse panel. Yours has something on top that mine doesn't have but it looks like there are provisions there to clip something on there. This pic is from when I was working on my wiring. The long bolts are gone and replaced with a neater set. There is also a breaker for the headlights that plugs into the panel next to the top bolt that is not shown in the pic.

The RWD Nova disappeared in 1979. Flat fuses were first used around 76 or 77 but I don't believe they were ever used in a Nova. The fuse panel looks like an OEM style. The flashers are for turn signal and hazards and the black box in the upper RH corner is a "multi-function alarm module" that would signal door open + keys in ignition, lights left on with key off, or seat belts not fastened. Is the fuse panel marked with circuit ID's in white letters? Brake, Stop, Cluster, etc or maybe with numbers? That could help match it up. Some '80s trucks had the flashers on opposite corners like pictured. Check out the fuse boxes and instructions on this page.

need a close up picture, looks like mid 70's chevrolet pickup.

I'll try to get a close up piccy tomorrow and update, I will lift it off and check for any inscriptions round its side too

Couldnt see any writing by the fuses, but from what i could see the fuses in are the only ones populated with connections for the fuselinks, the other carrier positions are either blanks or have only one end of the pair populated with a connection?

The module does look like an alm buzzer module clipped on the top

That's a useful article, thanks for sharing, didnt realise the block and connector split apart!

[1project2many]

The ones that have a single terminal sometimes do double duty as power taps for factory accessories. There are some special connectors that clip right into some locations in the fuse box. They're hard to find in parts books. I have a small collection I've saved from used cars / used harnesses.

You can find about any connector or contact you need here. When I rewired my truck I got some of the connectors from Pull-A-Part but used all new contacts in them that I got from this place.

Rear wheel drive Novas that I can find info on had round fuses up until the end of production in March 1979.

That looks like a factory unit out of a GM vehicle though.

Russell, thanks for the link. I'll look around on that site.

The connectors I'm trying to find look like these. The top image is a PT700 but there are others and the numbers seem tough to find. I did find an assortment for sale through American Autowire, seen at the bottom. But again there are others that seem to be missing.
