My 1990 RS has no power windows, no power doors, no speaker, no power locks, no power mirrors.....but when I open my door, I can see a fat wire harness plugged into the inside of my door. Can anyone tell me why is there wires going into my door when I have nothing to power? I would also like to know if I could use this plug that I see, and plug it into an LS door and it would power the windows and locks that come with the LS door?

Thanks Guys

 

heres the deal, they didnt just make each car by hand, they made them on an assembly line, the wiring to the door goes into the car and why make 2 types of wires when you can make a quick disconnect and just install part of it. Now you also have the option to run speakers, power windows, power doors, and everything else, its all good

 

nicesig slammins85.....about to buy a turbo........

 

bump for that

 

Never thought of that one SlamminS85, and come to think of it, it would make more sense to make one wire harness for all cars even though the car comes with manual windows and locks. I just want someone who has done it to let me know if it acutally does work.....i'm not discrediting SlamminS85 what so ever, I just want to know FOR SURE. Doors don't come cheap, and if I decide to buy them because I think I can just plug and play, and it don't work, I'm gonna be one broke sad guy with two useless doors if you know what I mean.

 

Bump

 

well, cant you go to a junkyard, pick all the parts off of the doors with power everything, then install it into your own door and plug it into the wiring harness?
