95 Mustang gt Need to ad a 6 ohm 50w load resistor so I can put some led bulbs in my parking/turn signal. It's a 3157 dual filament bulb. 1) Here is what I read: there are typically three (3) wires which are the two (2) positive wires for the turn signal and parking light function and one common negative. (you might need to guess which ones to connect? Most of the time, the common ground wire is Black and the turn signal light wire is Red) 2.) Remove the factory bulb socket assembly from the housing. For dual filament bulbs, identify the positive turn signal wire using a multi-meter and mark it That being said would my brown wire be my positive TUEN SIGNAL? I used a multi meter & only get juice to the upper right (piece of metal) in the socket. Here is a picture of the socket. http://s1174.photobucket.com/user/eg...?sort=3&page=1 Thanks in advance if you can help me.
