Can you guys explain this a bit more in-depth? I am not sure I am postive what you mean.

I believe a few of use was hoping to find out another way of achieving this beside resistors kinda explains talking about to BCM getting programmed. On the nbs all you have to do is change the flasher. I know I would rather not splice into my harness and solder some cheap resistors that get hot as hell next to the harness or the plastic head light housing IMO.

Did you get a chance to see your buddy?

Not yet. Shooting for Saturday when his boss is not in the shop.


There is also a car show/cruise/track day Saturday so hopefully we can make it happen.

And yes a few seem to miss the point of my original post. I know resistors will work but if all it takes is a quick reprogram I would much rather do that than hook up a bunch of resisters

that's why they're mounted on the frame... away from anything plastic. but if this can be done without, i would like to know. keep us posted..

I'd be curious if this is something Justin could tune out with the AutoCal

its simple electronoics, led are diodes which only use .7 volts. the computer doesnt see any current draw 20 you will need a resistor. a simple reprogram wont remap the circuit. power will always take the path or lease resistance. it takes 1 volt to push 1 amp throught a 1 ohm resistor.
