Wiring for a locking diff.

I am putting a rear end from a 99 pre runner with a locking diff. in my 95 4x4. Might anyone have some input to how to wire the locking switch?

 

Best way to do it.

3/4 of the way down. Call them first. I think they just came back into business.

 

Another option is getting your wiring harness and control kit from Inchworm.

This is the kit I used, and works great! Bypasses the ECU, so no need to do the grey wire mod. And be sure to get a e locker guard too! Don't want to damage your expensive motor...

 

Thank you all for the valuable info
