Toyota Repair: Toyota Estima Emina tail light problem, toyota estima emina, fuse box

Question
Ted - Thanks for an amazing website. My 93 CXR20 Estima now has no taillights after playing with existing trailer wiring yesterday. I have power at the fuse box under dash and the relay appears ok. There is no power at the tailgate and I don't know where else to look.

Answer
The problem is probably with the trailer wiring, I would recommend disconnecting the trailer wiring completely from the system and see if the rear lights work then, if so there may be a problem with the converter box used in the trailer wiring or a wiring problem, in either case the trailer harness assembly will probably need to be replaced.
