Hi All! Reverse lights don't work, bulbs changed...check. Connections all there...check. Even checked the battery and followed the wires into the engine compartment and don't see any missed connections.

Any suggestions?

Thanks

Is the reverse switch on the transmission plugged in as well? 2 small round bullet connectors plug into it under a rubber boot. Double check to make sure voltage is making its way through the engine compartment relay board as well.

The full path of the reverse light circuit:
It starts out by teeing off from the brake light switch (gray/brown wires) from there it travels to the engine bay relay board through the 14 pin connector (Pin 3), it goes through the relay board, out the 12 pin connector (Pin 2), down to the transmission to the reverse switch, back up to the 12 pin connector (Pin 4), back through the relay board, and then back out of the 14 pin connector (Pin 4), and finally out to the reverse lights. In all cases the wires for the reverse light circuit are the same color, gray with brown stripe.

Switch on transmission is good?

Starting to figure it is the pin, what page in Haynes? Or pictures.

Thanks

If there is a pin present then it's not that. You can check the switch after verifying that the pin is present by pulling the 2 wires out of the switch and putting an ohm meter across the terminals, if it doesn't drop to zero ohms when you shift into reverse then the switch is bad.

...or you can just unplug and jumper the two wires that plug into the back up light switch and shift into reverse with the key on. If the back up lights work, it's the switch.

The backup lights will be on in any gear or neutral with the key on if you jump those two wires, since you have removed the switch from the equation. But that is a good way to make sure everything else is working.

Hi All. Once I knew what to look for and got my 914 jacked up a bit, I found the loose wire, reinserted and have my back-ups.

Thanks for all the suggestions!

Cheers
