My rear window switch on my 86 4runner is actually missing a piece so I got to replace it. I figured I could just rewire my own switch on there but there are 5 wires connecting to the switch. I honestly have no clue why there are 5 connecting to the switch and if I need to use all of them. what is each wire? I havent been able to find a diagram of that .... or do I need to run wire from the relay by the driverside door panel? I dunno, could use some help here.

Mahalo!

 

one wire is for the light in the switch one wire is for the ground for the light.

the blue/red wire is the common

red/yellow is up

green/yellow is down

pretty simple to figure out with a meter

 

Yep.
Grounding red wire wire with yellow strip (R-Y) rolls window up
Grounding green wire with yellow stripe (G-Y)
Blue wire with red stripe (L-R) is connected to ground via window lock switch, cover top switch, and door lock detect switch.

Nice diagram!
