Ok, further update... I got to thinking that perhaps I hadn't tried running the truck to see if the msg came back on with the incandescent back in... So I tried it again today, and with the incandescent bulb in, the error message went away...
So, what ohm resistor should I be using to increase the resistance on the LED bulb?
And if I swap out the reverse lights with LEDs, am I probably going to need resistors for those as well? Same resistance?
