Default Rearview View Mirror Pinout

Just picked up a compass/temp rearview mirror from the local boneyard and am getting ready to install install it. I bought a mirror adapter from one of the members on the forum.
My question is do you have a pinout of the existing mirror connector so I can wire in my new compass mirror wires ( pink hot black ground) to the existing connector?

Pink/black = ignition power
Black = ground
Gray = power from headlight switch

My map light has a small bulb that is on when the headlights are on. It shines down on the console/shifter area. That's what the gray wire is for.

Some cars are set up so the map light in the mirror comes on when the courtesy lights are on (C5 & C6 do this). In that case the switch on the mirror is bypassed by the courtesy light circuit.

Like I said I picked up a GENK 177 from the local boneyard for $3.00 and bought a mirror adaptor from VetMed who had them for sale on this forum.
I took the old mirror off and soldered the old mirror connector to the new mirror harness. You only use 3 wires of the 177 mirror connector pink, green, and black. You solder the pink and green together and connect that pair to the pink wire on the corvette connector. You connect the ground black to black and your good to go.

I have to thank Cliff Harris and VetMed for making this mod work!

Thanks again
