[Ron and Susan]

I had problems with my rear turn signals and had to replace the relays that were located in the panel on the right rear side of the coach.

Then when I replaced the rear turn signals and the front turn signals with LEDs then
the flasher module would no longer work because of the reduced current drawn by the
front amber turn signals. The current used by the rear led turn signals had no effect on this problem because they were operated using the relays in the panel on the rear of the coach.

I replaced the turn signal flasher module with a module that had an extra ground wire and the problem was solved with the operation of the module. My coach is 1988 and should
be wired similarily to yours..
