Hi Jeff, it can but it is alot of work. That is what I have been into because my BJ7 was a car originally delivered to Europe and has the earlier European lighting arrangment in that it has the running lights and turnsignal lights separate like a BJ8. During my restoration, i found that I could not get a wiring harness for my car. I had to choose either a BJ7 harness that was configured for dual filament light sockets front and rear with the brake/turnsignal relay used Or a BJ8 harness that had the dash layout completely different than my car but no brake/turnsignal relay. I chose to buy an original BJ7 harness and change it to fit my car. It has been a PITA. Firstly since I have dual lights like a BJ8 I had to eliminate the brake/turnsignal relay configuration, in the new harness, which the standard BJ7 has mounted on the left from inner fender apron near the brake resouvor. That meant that the wires that goe to the relay had to be jumpered there and sent to the light sockets. But also the flasher circuit is different between the two cars and the wires to the trafficator are different because the trafficator switches the relay in one car, but switches the flasher directly in the other car. Had to reconfigure that circuit to make it work without the relay. Then too, the brake circuit is different. Basically there is no dedicated brake wire in the bj7. the brake switch operates the relay and the relay sends the signal back to the rear lights on the wire that is at one instant the turnsignal and at the next instant (during braking) the brake wire. so since I elected to use these two (left and right) wires for the turnsignals, I had to run another dedicated wire to the rear for the brake lights. Also this wire wouldn't go to the relay, it had to go directly to the brake switch. There were a few other anomallys that had to be worked out as well, but too much to remember now. It's not an easy or might I say practical job. Dave.
