This is something I've been pondering and haven't been able to find yet. If there's a sticky, please point me at it, but here's the question. I have an '07 Nissan Frontier to use as a TV. Had a hitch installed with a 4 wire flat connector, which I may change over to a 7 pin once the trailer is finished. The function on the connector is correct and it works well. My question is about the loads on the existing harness and electronics in the truck. The trailer I found is from about 2000 and still has the original filament bulbs all around. I tested this when I first hooked it up and things work, but... the turn signals are over-loaded once the trailer is being towed. Since I'm working on it for now, the wiring isn't a big concern or problem, but once it's in use, things will change.
I'm going to install LED lighting as far as the running, turn signal & brake lights go for the final build. These are a much smaller load and should be much easier on the TV's harness than the old stuff which functionally doubles the current load. Since the truck already has incandescent bulbs, will the LED wiring on the trailer work better than the extra loads created now with the two sets of filament bulbs? Hoping the LED stuff will cure the balky turn signal flasher issue. I don't want to fry anything in the truck, so am I missing anything here by changing over to LED lighting from all of the exterior stuff? Is there a relay needed on some vehicles (specifically the Frontier) to accommodate the extra loads I should be looking into now? Thanks in advance for looking.
