I'm working on a 2006 Accord with no taillights or license plate lights (reverse and turn signals are good). Fuses are good. Grounds are good. It has a pull-behind-RV trailer harness hooked into the rear lights (looks like probably just diodes where it 'T's in to keep the voltage from backfeeding? :dunno: It also looks at least somewhat profesionally done, no scotchlock connectors, anyway) I unhooked the taillight 'in' wire and it did not have power to it. I put 12v to the diode and the taillights came on. (so it's nothing behind the 'B' pillar - I'm just glad I didn't have to get to/find the rear junction block :rolleyes:).

The wiring diagram shows a taillight relay in the underhood fuse/relay box, but there is not one. I even took the box apart thinking there may be a hidden relay under the hump next to the lid, but nothing. Do they hide it somewhere else or is there not one?

The car's coming back on Thursday :banghead: , so I'd really appreciate any help by then. Thanks.
