I have standard FFR front turn signals and LED rectangular rears. I followed advice and fitted a trailer module to allow for taillights/brake and turn signals to do what they are supposed to. And I replaced the flasher for an electronic type. Everything worked good, and it still does with ignition on. But when engine is running the fronts flash ok, but the rear stays on on PS and when I change to DS that flashes erratically. Brake lights work fine, as do tail lights when headlights are on.
Could the trailer module be faulty or flasher unit?
It's going to be a right pain to get to the wiring to remove the module, but it is something I will need to resolve! Any ideas appreciated. Thanks
