Thanks for the reply. I actually was feeling the resistors after driving The other day and they were very cool compared to what I was thinking...it was maybe slightly warm. I’ll have to do a test where I leave the hazards flashing for like a half hour and do a temperature check and see if I really need to move them.I don't use this setup, but I can already tell you that load resistors both have no business being inside your cabin, and have no business being used continually...
I use load resistors for my own LED turn signals only for the exact reason you specified: Heat. Components that get hot and are not OEM installed have no place anywhere in your vehicle cabin.
Instead, I put mine right next to each turn signal housing, and lined the nearby plastics with foil.
The only exception to this is the 5th resistor, which is on the LED high beam circuit, and sits on a metal rail under the battery, and away from any other wires...
The point? get your load resistors away from plastics, and preferably out of your cabin altogether.
As for the heated plastic smell, it may have been coming from something else...all the extra led’s I’ve installed are still functioning and powered, but the passenger/right HID lowbeam headlight and switchback turn signal sh*t the bed 2 days ago...sorry for the crude expression. I’m hoping it may be just a loose harness or maybe a blown fuse? Haven’t had time to troubleshoot, glad I didn’t encounter any cops the past two nights...but I guess I would’ve been ok with my eyeline switchbacks and side mirror turn signals still working. Best case scenario it’s just a loose plug on the harness from when I recently tapped into the harness and installed the eyeline switchbacks...otherwise it’s a short somewhere and I need to troubleshoot my passenger side wiring and fuses.
anyone have any tips or tricks for giving my setup a good troubleshooting and make sure everything is ok? Would a laser thermometer work to find any wires that may need to be bigger gauged or potentially problem areas? I don’t think that’s an issue because I installed verylow wattage leds except for the turn signal replacement switchbacks from this thread, and probably used way overkill wires, and I soldered all connections and heat wrap or electrical tape all connections.
I love and hate wiring up my own stuff...love it when it turns out great 99% of the time, but that other 1% of the time, like now, I’m ready to punch my fist through my windshield in frustration. It may just be a coincidence and not even the fault of anything I wired up...hopefully I can figure it out tomorrow finally on my day off.
