I am going to put a tc switch in tomorrow. Let see if I got it right for 03 48re tap into pin7 run wire to one side of switch out to ground. Go to fuse box run jumper wire from pin 30 too pin 87 NOT 87A. Was looking in parts box found a push stop button that when you push it in on hold it will make contact when you take pressure off it breaks contact it has big red button on top. I am planing on putting it in floor in left up corner were the old high beam used to be so I can hold it in with my left foot. If this wireing is not correct let me know and if any have the switch in this place let me know how it works out for you.
