[CorvetteBeretta]

Next Sunday is my install day I will post tonight the wiring for you. I have all my switches finished and working

[CorvetteBeretta]

As requested here is the wiring

Headlight connector wiring:
Cut the headlight connectors off both your old and new harnesses making sure to leave several inches of wire protruding with which to splice. You can toss the old connector.
Splice the orange wire of the new harness into the orange/white wire of the old harness
Splice the white wire of the new harness into the white wire of the old harness
Splice the green wire of the new harness into the pink wire of the old harness
Splice the black wire of the new harness into the black wire of the old harness.
Splice the red wire of the new harness into the red wire of the old harness
Splice the big yellow wire of the new harness into the yellow wire of the old harness
Splice the brown wire of the new harness into the brown wire of the old harness.

NOTE: The gray wire in the old harness isn't used. The small yellow wire in the new harness leads to the fog light wires in the GTZ's. Your new harness may or may not have the small yellow wire. To add your own fog lights controlled by the GTZ fog light switch (if you have it) you can run the small yellow wire to your fog light relay. The red/white wire you'll have in the new harness if your donor car is Canadian goes to the DRL module. The spare big yellow wire in the new harness also goes to the DRL module. Test everything before wrapping it all up nice and pretty with electrical tape.

As for the wipers/defogger

WIPER/DEFROST connector wiring!
Cut the big connectors off both of the harnesses the same way you did the headlight connectors making sure to leave room to splice. Toss the old connector.
Splice the red wire and the brown wire off the new harness into the pink wire of the old harness
Splice the white wire of the new harness into the white wire of the old harness
Splice the green wire of the new harness (might be green/white) into the green/white wire of the old harness
Splice the purple wire of the new harness into the purple wire of the old harness
Splice the big gray wire of the new harness into the big gray wire on the old harness
Splice the small gray wire of the new harness into the small gray wire of the old harness
Splice the black wire of the new harness into the black wire of the old harness
Remove the metal rear defogger timing relay from beside the right side of your steering column. DONT CUT THE WIRES, JUST DISCONNECT THE CONNECTOR. You don't need this relay as the timing circuit is built into your new defogger switch. Cut off all the small connectors at the wiper/defogger switch the same way you cut off the others. Toss the old connector again.
Cap the black wire and the blue wire, you wont need them.
You can completely cut off the defroster timer now and run the orange/black wire straight up to the defroster switches little connector and splice it into the orange/black wire of the new connector
Splice the purple/white wire of the new harness into the purple/white wire of the old harness at the wiper defroster switch, NOT AT THE RELAY)
Splice the pink/black wire of the new harness into the pink/black wire of the old harness at the switch and NOT THE RELAY.

91+ Diagram, I don't have the 88 one

by chance do you have any of the 90 GTZ wiring diagrams?? or would these work for that application?

[CorvetteBeretta]

This should work just gotta follow directions for gtz fog lights

The wiring for the GTZ fogs runs on the totally opposite side of the car - down the passenger pillar and through the firewall on the passenger side only to cross back to the driver side in the engine bay. If it were me, and the switch being in the overhead console, i would find a non-fog headlight switch and make the conversion with it and leave the fogs alone in the GTZ. Just my $.02.

Dash is still not in!!! First my daughter (3 year old) got very sick the day I was suppose to install, ended up going to the hospital. Then my wife and 5 month old were both sick (wife still is). I thought I was superman, the only person not sick and then WHAMO I'm sick!!! Damn IT! So amongst all this sickness I'm involved with I found a few hours here and there to escape and paint some trim pieces. Here is progress on that and install date is unknown, now I have to wire in the 96 steering column.

Cell pics though

Finally got it in!! I did it solo I was tired of waiting for help. It's not fully finished yet but close 96 door panels are next...
