I have an 87 4runner M/T. Having wiring issues. Wanting to replace Sub Harness, becuase someone previously butchered it to crap. So my question is, can I get a harness from other years 89-92??? or from other trucks even if they're automatic? Does the harness differ that much? I found to suppossedly stay away from the 88 cause they changed some plugs or did diffeerent pin outs for the ecu.... And If anyone has a good untouched harness they would be willing to sell. Live in Fl.

 

Sub harness??
I don't think they put subwoofers in these trucks.
And you're better off just rewiring it anyways.
