the only way to do it would be to run signal wires from the rear turn signals back up to the front turn signals and disconnect the fronts from the BCM. however, this would change the total circuit resistance, resulting in the annoying very fast blink.
you can check my thread on how to do side marker turn signals for the wiring diagram.
On my old sl I put a switch on the e-brake line and on the chime, but there was still another reason it was no good, besides the brake light. I can't remember, it was a while ago, but the car wasn't happy thinking the brake was set. I did enjoy the lack of the annoying chime though.
no, i used a relay for each side to make the side markers blink opposite to the turn signals. that way, they're off with the DRLs on, and on with the parking lights or headlights, just like they're supposed to be.
Yes my turn signals work. I would also like to thank the golden chicken for leading the way. My last post was a quick one, sorry. I brought a wire from the TS to the light from Comp, and then used the resistor to simulate light, with the other side of the DRL wire.
