Toyota Repair: power mirrors, toyota tacoma 4x4, toyota tacoma

Question
Is ther any way I can tell if my 1999 toyota tacoma 4x4,v6,trd,ext cab. is pre wired for the electric outside mirrors and the control switch for them? Thanks

Answer
They are not prewired, if it didn't come with power mirrors from the factory then the wire harness will be different and there are no wires for them, in other words there is just about no way to add power mirrors unless you want to change wire harnesses as needed.
