identify wires

after pulling my front sheet metal off my 69, I discovered these 2 wires tucked in behind the wheel well. I didn't put them there, so I have no idea what they are suppose to hook up to. One is a heavy gauge wire, the other is thin. Are they oil and water sending unit connectors?
And in the second picture, I found this ground wire coming off the side of the rad support on the pass side....where is the other end of it suppose to be attached?
Looks like I've got to go through and organize and re-tape the spagetti mess of a wiring harness I have right now
Thanks in advance for any help

Re: identify wires

Can you tell where the wires are coming from. Directly from the fuse box or where in the wire harness?

Re: identify wires

Ground wire may have been from front headlamp socket.
Color of the two wires?
Green would be for the temp sensor between Cyl's 1 & 2.

Re: identify wires

Blue wire with no end could be the oil pressure sending unit if it's at the firewall - hard to tell from your picture where it is in the harness.

Re: identify wires

the large red wire comes directly out of the fuse panel...the smaller wire comes out of the harness....

Re: identify wires

you can see where the large red wire comes out of the fuse panel, and what the ends of the 2 wires look like, and where the smaller wire comes out of the harness. The smaller of the two is green.

Re: identify wires

Driver' side - The green wire is for the temp sender in the cyl head, probably an idiot light type.

The red wire looks like an anti-dieseling solenoid wire, which would have connected to a solenoid at the front of the carb, driver's side. (excellent wire to use for aftermarket ignition pos wire, btw)

Pass side -

Looks like a headlamp socket ground. If so, it'll be a short wire that goes directly into the back side of the haeadlamp socket. Originally would have had a ring terminal on it and attached to the core support just ahead of the battery.

Re: identify wires

thanks for the reply Al. The car was originally a bare bones base model with only the idiot lights, no gauges or options of any kind. Original engine was a 307 2bbl, so eevrything you mentioned makes sense to me.
On the ground wire, the headlight socket has 3 wires going to it now, is the ground wire suppose to be attached to one of those? if so, which one?
Thanks again for the help...I hate electrical stuff...but I won't run from it either.
