How do you put electric mirrors on both sides of a 1997 Mercury Tracer LS?

i did something close to this on my truck i installed power windows that i had bought from a wrecking yard. if this or any other way of getting the parts is the way your going get get all the parts that you need or think you need and install your mirrors most newer cars already have wires run for any thing that could have come electric if this is the chase hook the wires up and you should be good but if not don't get scared. if you have to just take what trim you have to and run the wire from the mirriors to the switch ( you did get all the parts befor you started right) and then do the same for the other side and once your wires are run from the mirriors to the switch run the wires from the switch to the fuse box you will have to check your with volt meter to find a lug that turns off with the key most of the time is in the center and then hook it to that lug and if your fuse blows just install a bigger one that's what i had to do on mine
