hi guys--
wiring issues here. I have an acura integra, and the brake lights utilize 1 1157 bulb each side (dual filiment 21/5w). I plan to add one more 1157 bulb on each side so that when I brake it is very bright. Fabrication is the easy part, I wont have trouble with it, but my issues deal with the wiring. How do I go about doing this so that the new bulbs will work as parking lights and brake lights as the original bulbs do? There are three wires that connect these bulbs: one is the brake, one is the parking light, and one is the ground. I'm probably going to have to use relays, yes? How do I go about doing this? Thanks for any help.
