Are all the electrical things in your radio console area working, like the cigarette lighter (and its illumination ring), the hazards flasher switch, the courtesy light, and the radio (power, ground, power antenna, speaker wires, antenna)?

Based on how it should be wired in a 1977 spider, here are the wire colors:

Cigarette Lighter: Red (power), Black (ground), Yellow/Black (illumination ring)
Courtesy light: Black (grounds to door jamb switches), White/Black (direct to ground), Violet/Black (power, connects to Hazards switch)
Hazard switch: Violet/Black (connects to courtesy light as above, Violet (power), Red (to hazard flasher relay), Grey (to turn signal flasher), Light Blue/White, Grey/Red and White/Black (illumination light, power and ground)

Factory radio power antenna wires are often:
Dark Blue/Pink (or Red), Violet, Light Blue/White

By looking at what circuits aren't working, and whether your loose wires go to ground or power (measure with a voltmeter), you can probably piece together how this should be wired.

Thank you kindly for the insight

Right now I am trying figure out wiring for the reverse lights.

Wire are such as mess and some one has been in here before.

This drive shaft broke and tore up wiring for transmission Rev light.

Found a white wire when I power probed and added power to rev light on one side came on guessing.other light burnt out.

I am trying to figure out where I can pick up power for this switch. However not knowing fuse box I a leary of using a random power. Would like to to move on.


Rather not run a relay and in line use if I don't have to.


Try to see if I can get this thing back moving first
Then I can always as a relay and like 10 powered fuses to take load of ignition.


Is there a power wire that I could use for Rev light that won't cause a power problem
?


Thanks again
