What is the "Compt L.P."?

The 70-71 electric diagram shows "Compt L.P.". Where is it? Is it the glove box light?
---Can not be the rear console light because it is on the same white wire circuit as the dome light and only lights up when a door is opened or headlight switch is rotated.
---Can not the dome light which is on another sheet.

Never seen a diagram of just the grounding circuit, do you have pic of the corresponding power side of that circuit. Because if that compt L.P is fed by an orange wire that would match up to what feeds the glove box lamp in my 72 diagram. What # receptacle does the blk wire go into on that large connector in lower right corner of you pic (I am assuming that is the connector that 70-72 had that split the main under dash harness into 2 pieces, it is located over your right foot). On my 72 diagram I am showing the black for the glove box ground (after tying into other grounds like radio, clock/lighter) going into receptacle #130 on the main harness connector. I'm pretty sure you are right assuming that is the glove box light. Was there a switch in the glove box to turn the light on? Wondering how they activated it, if the ground wire just goes to ground then the power wire was switched. OK just looked up glove box light for a 1971 Caprice (figured a more luxurious car would have one) and results came up for Camaro and Nova also, pic shows light bulb and switch assembly as one unit, and it appears it has a male spade terminal that the ground wire hooks up to. 18 Ga ground wire seems right size for a bulb circuit.

When a circuit gets confusing to trace out I remove what is not involved

It must be the the glove box being on one of two orange wires. My 71 never had one. I misread the two symbols as separate because they are not connected with a line. Thought the ground symbol was to metal, like the door jam sw and license plate light sockets

A second orange is for the "Cig Lighter Conn" but it shows no return wire

Yet there is an orange wire for the center console rear light which has a return through the white wire circuit. The electrical diagram does not show this light. Like the dome light it comes on when the doors are open or the headlight switch is rotated. There are only two orange wires so this light must get it's power from the glove box supplied orange but has a separate return to the white wire circuit

I am installing a glove box light but different from the factory. Modifying a junk side marker for a light socket to be placed in the middle of the hard plastic Vintage Air glove box shell.

Yea, you can see the other ground symbols have a "ring terminal" end on them whereas the compt L P just has a ground symbol, but no ring term. I think the cig lighter has the same thing, a spade terminal built into it, it may connect to a wire that also goes to instrument panel versus another running alongside the orange wire, I can't recall exactly anymore. Funny, I last had a Z in 1980, but those old wire colors and some of the circuits came right back to me working on my 72. I had built my own bezel, all aftermarket gauges, wired witha bunch of stuff from the Iveco truck place I worked at. I'm still sitting on an ammo can ful of Iveco courtesy lights, wire, terminal blocks, windshield washer pumps etc. This is the dash I built when I was 20, no one I knew was doing anything like this back then, I wired it all using junk (bad from the facotry) rear tailight harness' from Iveco trucks, nice 15-17 foot pieces of automitive grade wiring. Of course I was the resident expert in wiring stuff in for friends and usually ended up doing distributor drop in and wires when getting ready to fire up a fresh engine cause they could never get it right.
