Potter, are you going to have cruise control? I was told to add resistance to the wire(I used a relay instead of resistor) on the white wire on brake switch because i'm using LED lights plus DBW CC. The cruise needs to see 12 volts to kick off and the LED lights supposedly don't draw enough voltage for the TAC module to see it.
Here is LS1Nova71 post on this:
