I have been wanting to do the DTRL mod on my 06 tacoma but don't want to pay for the harness. I've been thinking about taking the positive wire from the factory DTRL and moving it into the third hole on the blinker. The third hole, that's currently empty, is power to the low power filament in the bulb. I jumped power from the running light socket into the third hole and it functions correctly and still allows the blinker function.
My question is, will this have any bad effects? I know that my model headlight is prone to having the DTRL lens melt and that would probably happen even with the harness. Will this be more of a hazard than just the normal melting?
