gergeek Posted May 12, 2012 Author Share Posted May 12, 2012 thanks... this is going to be interesting.....so this needs a relay to work as an on and off switch correct? Link to comment Share on other sites More sharing options...
sdavidson7014 Posted May 12, 2012 Share Posted May 12, 2012 my expierence with wiring is minimal, but from what i can see it looks like it needs a relay, but the stock relay is there so i dont see why you would need to install another one. I could be way off though..good luck man Link to comment Share on other sites More sharing options...
sdavidson7014 Posted May 12, 2012 Share Posted May 12, 2012 Seems to me whatever your trying to run by this switch you could just run the power and switched wires to the power from the defrost, then the ground obviously to the ground. Not sure how complicated whatever your trying to wire up is. Link to comment Share on other sites More sharing options...
gergeek Posted May 12, 2012 Author Share Posted May 12, 2012 trying to wire up a "Power Mode" button....i have everything figured out except the switch. Link to comment Share on other sites More sharing options...
gergeek Posted May 12, 2012 Author Share Posted May 12, 2012 would you happen to have the fog light switch diagram? Link to comment Share on other sites More sharing options...
sdavidson7014 Posted May 12, 2012 Share Posted May 12, 2012 http://i72.photobucket.com/albums/i190/sdavidson7014/fog.gif yea im not too familiar with the power mode set up since i have a 5mt, but the switch should be the same as wiring in any switched component.12v(constant) and 12v(switched) go to power and ground to ground.

gergeek Posted May 12, 2012 Author Share Posted May 12, 2012 well installed all the wires....so it should work for now just have to hold down switch.....will have to figure out and ask around on how to turn the switch into an on off switch Link to comment Share on other sites More sharing options...
gergeek Posted May 12, 2012 Author Share Posted May 12, 2012 so i can use the switch just have to hold it down....guess it is what they call a soft touch switch and i just need to buy a relay to set it up. What im trying to do is to get it to turn on with one push and have a light come on and then off with one push and the light will go off Link to comment Share on other sites More sharing options...
johnegg Posted May 12, 2012 Share Posted May 12, 2012 on the defrost diagram, it looks like pins 2 and 4 are for the illumination light, headlights on. and pins 3 and 5 complete a circuit when the switch is on. pin 5 is the ground so i would run the wire from the TCU to pin 3 . when you turn the switch on, push it in, the tcu wire will connect to ground . this is what you want. getting an indicator light is a little more challenging. if you have a 9 V battery and some wire, and a test light you can see what it tskes to light up the illumination and the indicator bulbs. by the way, these little bulbs are notorious for burning out. if you have a rear defrost switch on your car already and both bulbs work, you might consider testing that one. or swapping them to test your new one.

gergeek Posted May 13, 2012 Author Share Posted May 13, 2012 it doesnt seem like the switch is an on/off switch. but right now if i hold in down, it completes the circuit and changes the shift pattern but once im not pressing the button it goes back to the normal shift pattern. How did you wiring yours up? Link to comment Share on other sites More sharing options...
johnegg Posted May 13, 2012 Share Posted May 13, 2012 what car did it come from. i used a rear defrost switch and it is in on, out off. it came from a 96 lego. my 97 is the same. not sure about 98 or 99. Link to comment Share on other sites More sharing options...
gergeek Posted May 14, 2012 Author Share Posted May 14, 2012 1997 lgt.....but i can just go back and get another one later on, it works for now. pushing it down gives me power....its ok this way its is saving me gas not using it all the time haha......now its like a "Hold for Power" button Link to comment Share on other sites More sharing options...
