[66Sprint200]

Hey can someone tell me what these are? First this is a picture of the dash right under the ignition switch & cigar lighter. In the picture there are 2 screws in the holes I am asking about. Was this the mounting location for a factory or dealer option?

Second is there is a random yellow wire in my engine bay with a male connector sticking out near the starter solenoid. I thought this might be for the air conditioning, but my wiring manual says that the air conditioning wire should be black.

Can anyone help please? Thank you.

i do not have those screws in my 66 dash

I'm guessing it had some kinda ignition kill switch is why the screws are there and that wire which is not nothing factory.

I agree that those screws in your dash are not from the factory. They are red since everything, including the vent knob has been re-sprayed red.

The yellow, male wire near the solenoid is an ammeter connection. It should plug into a female yellow in the bundle going along the right inner fender that eventually goes to the ammeter. That same bundle should have a red wire with a loop on the end that connects to the big solenoid terminal closest to the battery. That is the OTHER side of the ammeter. The loop on the red wire is flimsy and tends to corrode and/or break off. The car is wired so that disconnecting both of the ammeter wires does absolutely nothing except disable the ammeter.

I know the screws don't go there and that the previous owner did a crappy repaint, but I thought that maybe those holes were supposed to mount the optional seatbelt warning light. The Sprint 200 package included deluxe front & rear seatbelts, so that is why I was asking.

I thought of that also but I don't think so. The screws are a little to the right of where the seat belt light goes. My light is left-right centered between the ignition switch and the lighter, not under the lighter like your screws. Mine is about where it looks like you have a smaller, open(?) hole. Not knowing who punched the original holes, or how, the factory location might have varied? The screws also seem more widely spaced than the body of the light which is only 1.25" to the outside of the chrome body.

I felt the back side of my seat belt light before I wrote the above reply and I didn't think I felt any screws like that for a mount. Just now I did a stand-on-my-head-routine and checked out how a factory '66 seat belt light is attached. This is a V8 coupe with factory Deluxe Belts for which I have the original sales invoice; a dealer written one signed by the original owner who sold me the car, not a typed window sticker. There is about a 5/8" diameter round hole in the dash metal. The light body goes in from the driver side then a coiled spring is placed around the neck of the body and a sleeve is screwed onto the back end of the neck. The visible light body is held against the painted dash by the spring tension of the spring squeezed by the threaded sleeve. There are no screw holes.

Whether or not the Sprint had Deluxe Belts I do not know. But if the car had a seat belt light, which I though was part of the Deluxe Belts, then where is the finger sized hole that should have been in your dash metal?

Ok, so I didn't have a warning light. Can somebody post a picture of the 66 Ammeter gauge connections near the starter solenoid so I can see if mine is missing part of the connection.

Its getting late so this isn't the best picture, but here is a factory original Dearborn wiring job on a '66 coupe soleniod. Its a 289 but I don't think that makes any difference on this part of the wiring. The red wire goes under and behind the solenoid and connects to the left most solenoid bolt under the battery cable where you can't see it in this picture. You can't really see the connection in real life either unless you really look for it.
