i just got some 4th gen seats.......the drivers side is power but my car doesnt have that power seat harness under the carpet some ppl talk about......wireing is no problem at all sinse its just power/ground but what should i tap into for power?

 

what color r the wires? u have to work with and do they match the wires that r on the seat itself

 

the wires r black and orange, but i just need to know what current power source i could tap into for power, i was thinking my stereo but my tach is allready using that power, so i would think that my stereo, tach AND power seats would be too much for that one power source.........

 

i just had an idea.......my shift light is in my cig lighter hole so i dont need the lighter anymore, would i be able to use that? would that be sufficeint power for the seats?

 

i think youll blow the fuse

 

you could run a wire off the battery through the fire wall to the seat!

 

i could do that, but id have to run a fuse that way too.....could i just put a bigger fuse in place of the cig lighter fuse? (assuming i blow the cig lighter fuse)

 

I JUST WORRY ABOUT FRYING THE ECU IT CAN HAPPEN WHEN THE WIREING IN THE DASH IS MESSED WITH THATS ALL. THE CIG LIGHTER WOULD WORK BUT THE ECU IS MY WORRY

 

I would go to the fuse block ,but the lighter should support your seat power.

 

i dont see any way it can fry the ECU.....

it doesnt need a constant power source, just the few seconds the seat is being adjusted......

thanx for the input

DON'T just use a bigger fuse to make up for the extra current draw. The factory wiring is very borderline on current capacity in places and it can melt and cause a fire. I have a car in my shop right now that is having to have $1500 worth of work done because the guy didn't know what he was doing and caught his engine bay on fire (bad wiring+leaky injector=big, big flames.)

Your best bet will be to use a male spade terminal and plug it into the open IGN port on the fuse box. If you already have something else powered there, you should be able to tap into the lighter circuit if the shift light is the only other thing hooked to it. If it blows the fuse, unhook it and find another power source. You need to run at least a 14ga wire for the power seat motor.

Either way it's not gonna fry the ECU.

 

judging from your wireing work in ur 91RS (fully rewired) i take it you know a thing or 4 about wireing......so ill listen to you

 

I was an electronics tech in the Navy.....I kind of have an idea which way the current is supposed to flow.

 

couldent u run a wire right from the battery and run a inline fuse.....

 

i could, but if the cig lighter wires will work ill do that cause i dont wunna have to run more wires into my engine bay, with the lighter there wires r allready there
