I have a plug that isn't being used right now. I am trying to figure out where it is supposed to go.

It has an orange wire going back to the fuse panel. 2 white wire spliced together on one terminal, and a Wh/black wire on another terminal.

Perhaps a connection for the alarm system?Jim

Maybe, if this car had an alarm, it is long gone! Lots of jack leg stuff going on behind with the instrument lamps. Ended up blowing the fuse for them last time I drove at night. Cleaned it up quite a bit today and heat shrank all the splices. Should be much better now.

As you guys say here, bubba has been in there pretty deep, and now I am trying to get it right.

After finding this picture, perhaps the interior lights are supposed to have some sort of delay module! Mine shut off as soon as you shut the door. I think it might be this transistorized module on the right side of this schematic.

IF you have the car's 77 owners manual there's a good description of the features and accessories as well as a chart for fuses, what they are and what they protect.
My 78 had an alarm activated by the driver's side door lock( counterclockwise armed it)

Look under the hood, Driver's Side tucked down deep under fender and SEE if the alarm horn is down there..Mine had the orange wire as a hot wire..

The alarm, courtesy lights and clock were all on the 20 amp SFE fuse top left in fuse block..at least in my 78..Jim

That plug is for the courtesy lamp timer relay.

Thanks. I see no real reason to try and hunt down a replacement timer. This car is quite customized and nowhere close to an original restoration.

I think I might just remove this extra plug altogether, and fix the wire tap splice that makes the courtesy lights work.

I have a 77, and this is indeed for the timer for the interior lights.
I removed mine and the interior lights turn off instantly.

Timer for the interior lights

I want to remove my timer. How do I make the new connections to make the courtesy and dome lights still work, but with no delay?

You just disconnect the socket from the harness, then connect the two white wires together.
