I have a gentex dimming rear-view mirror. Does anyone know a wire i can tap into that so that when i do shift into reverse, the mirror DOESN'T auto dim. I have a 98 camry le i4 auto.
Right...you have to get a specific relay that is normally closed, and then when activated is 'open circuit'...Maybe I can find one someplace...
Red with black stripe, thanks.There is a reverse wire ...red with a black stripe ....that goes from the Neutral Safety Switch to the ECU ...and should be high...or 12v...when you shift into reverse gear.
You can probably access this wire if you look behind the right side passenger kick panel...Try to find connector J27...Check the wire with a voltmeter, as you shift into reverse.
Just to clarify...you want to inhibit the dimming feature of the mirror as you shift into reverse ...right? ... So that your reverse tail lights give you some illumination.
If the power to the mirror were deactivated when you shift into reverse, would that be sufficient?
Do you have any sort of wiring diagram or schematic of the mirror installation?
It looks like you might be able to use the red/black reverse wire to activate a small relay that would turn off the power to the mirror ...when in reverse gear. Do you think that would work? ... That is, when not in reverse, the mirror would receive 12v, and when in reverse, the mirror would be off.
Right ... it looks like the mirror just needs 12v from the reverse wire ...when you shift into reverse gear. See if you can locate the red wire with a black stripe...It looks like it is behind the right passenger kick panel...going into a connector probably...If you have a test light or a meter, check to see that the wire that you pick is the right one...and gets 12v when in reverse gear.Red with black stripe, thanks.
My mirror has 5 pin. 1st one goes to 12 volt red(ignition), 2nd one goes to ground and 3rd one disables the dim when in reverse.
So when in reverse it would get some kind of charge on the 3rd pin and it would disable dim.
