i am thinking of adding a power defroster to my car and i was wondering if the wiring for the hatch is already run with the rest of the wires to the back of the car ? or would i have to run a 12v wire to connect to the hatch ?

also i took off the panel on firebird where the switch would be if i had a button for the defroster and there are wires in there, would that be the wires for the defroster button ?

i can get a panel out of the junkyard with the defroster switch in it, and i can get teh whole hatch for like $20 so i was wondering if it was worth my time

i understand that the connecter on the drivers side is the 12v positive wire, and that the one on the pass. side is only a ground, but i was wondering if the wiring was already in teh car, even though it wasn't origonally equiped with a rear defroster.

 

if the wires in the dash end in a 5 pin plug with pink/black, grey, lt. blue, purple/white, and black wires then yes the m are the ones for the switch.

at the rear there would be a purple/white wire on the left side that connects to the LH hatch support arm and then a wire going from the RH hatch support arm to ground.

Your going to need the hatch support arms as well as the window.

gook luck.

 

my hatch support arms already have the tabs on them for the connectors, should i be ok, or should i grab them off of the donor car as well

 

you should be set then.
