Hi, is anyone familiar with the wire harness the operates the power mirrors on a 1999 tacoma? I'm wanting to put electric mirrors on my truck, but this seems to involve alot of stuff. I can get the swtch and the mirrors for a decent price, but the harness is very expensive. I'm trying to look for one at a junk yard. Is this a single harness that goes from the switch,to mirror,under the dash to the other mirror, and plugs in somewhere? One guy told me its a 3 piece harness. Thanks
