Hey guys, Well, I bought a manual from eBay to identify all my wires but it's complete crap and I can't read anything. 1st. Does anyone know where I can get an assembly manual that's legible? 2nd. Can you help identify the following under the dash...
Not sure what year you have, but I can check under my 70 dash tomorrow. I believe the double wire bulbs are for the heater/ac controls since it doesn’t have a metal ground case connection. Single wire bulb is up in the clock. I recall a single brown wire for tach if you have that option. I think the single orange is constant power for the cigarette lighter. Where does the double red exit the dash? And @ToddsGS carries wire diagram in large format so he’ll just need to know what year you have. https://www.stage1restoration.com/product-category/wiring_diagrams/ Nick
Guess I should have mentioned that. It's a 1970 GS. Thanks for the help. Heater/ac check clock check using an aftermarket tach so I don't need the brown. Cigarette lighter makes sense. It's a double pink, I'm not with the car now but I believe it goes to the steering column. Man wish I Todd's diagram a year ago, thanks for the link!

I think the double pink wire may be to the back of the speedo for the speed minder buzzer if you have that option. Especially if you follow one leg of the pink wire and it goes to the door buzzer which is located to the back of the metal dash just above the glove box.
Bought the wiring diagram from Todd. Speed minder is interesting, I didn't know that was a thing in 1970. I'll have to check if it goes to the door buzzer.
Wiring Diagram is on it's way!!! Let me know if you have any other issues or questions. We've worked on a few of these. .
