Well time for the quarterly update!
I also re-worked the reverse light wiring so I can use the switch on the back of the tranny instead of the 3-sp on the tree wiring it had. I also had to re-work the brake light wiring as I am running the later model lights with separate brake/turn lights. The rear harness also got a ground buss for all the lights and a towing plug. All connectors are Weather-Pak connectors.

Modifying the FJ40 wiring to use the later style rectangular lights is not that hard. I covered that here:Brake Lights
If there is a switch on the tranny that makes connection when the tranny is in reverse then by all means it can be used for the reverse lights.
If you are serious about doing this I could build you a new rear chassis harness from the firewall back. It would have all new connectors for the rear lights, T-case light (if you still have this?) and if you verify the function of the tranny reverse switch I can include a connector for that also. Last, if you sent me the tail light housings I could add Weather Pak connectors to them and the harness.
Figure about $150 for all the above. I would need you existing rear harness to get some measurements off of. I would return it if you wanted it back.
FJ40's never had a neutral safety switch so don't worry about that too much.![]()
Having reverse lights however would probably be a good thing...
You can email me or PM me if interested.
