Default Power Mirror conversion

I may have to replace one of my door mirrors, I have a 1990 LE, how hard would it be to just add power mirrors. The local yard has about 5 SSE'* with the power mirrors, is it a self-contained system? Just add power to the switch for controlling the mirrors and run the wires to the doors? Or is the wiring more complicated than that? I assume they bolt up the same. I also like the thought of having heated mirrors if possible, trying to scrape the frost is just impossible on a tiny little mirror.

Thanks

Easy. I swapped '87 power mirrors to a 90 Olds.

Err.. I don't know if it is plug 'n play man. Our older gen doesn't seem to be as pre-wired as others. Do you have an LE or SE? I can pretty much garantee an LE isn't going to pre-wired. And SE is questionable. If it is pre-wired, it'll be pie. All power mirrors are heated, btw. They are activated by the rear defrost circuit [IE when you turn on the rear defroster] just in case you didn't know. And, just in case if all power mirrors aren't heated, ALL the heated mirrors have a blue-ish tint to them.

I guess I'll just go to the yard and get some and go from there

I don't expect them to plug in, but I just wanted to make sure there weren't any MAJOR differences in the wiring in the cars with or without power mirrors. If all I have to do is find a power source and wire up the mirrors and switch (which should be the case) that will be fine.

Thanks!

Eh, easier said than done.. but it wouldn't be that hard. I haven't had my front door panels off.. so I don't know where the plug is for the mirrors.. but maybe you should have someone chime in on where the connector may be located, then take off your door panel and see if you have it. What trim level do you have?

I don't need a plug to be there, just need to know how many wires I'll end up running to the door assuming he plug isn't there. I'll just use a 12v source and hook up the defroster for the heat.. and I am hoping those are the only extra wires needed, if that is all, it should be pretty easy.

Don't do it if you don't have an FSM, and I am guessing you don't. No offense, but it seems like you are underestimating the power of Bonneville electrical . Don't say I didn't warn you, if it doesn't have the pre-wired connector.

I have an FSM, and it does look like a pretty much self contained system, I was just seeking a little experience before I buy the parts and get the door panels off. I rewired a 68 Caddy with all the power options possible last summer and found out very quickly that wiring diagrams aren't always completely accurate. Thanks for the input, I'll figure it out.

Thanks! I'll grab some mirrors and the switch next time I am at the you-pull-it yard, which will probably happen when the weather warms up a little so I can take my time pulling as much of the wiring with the mirrors as possible.
