Hey guys I put factory lockers in my 91 fj80. These trucks have curved dashes so I did not want to use some after market switch. I found a factory rear defog switch on ebay that fits the curved dash winning. it took 3 relays and some brain power. Then I got it working here are a few pic feel free to ask any questions for more detailed info. The wire colors in the diagram are from a harness I made not factory colors. The best part is i don't need to be in 4 low to make it work and I can choose to lock the front and rear independently from each other. instead of locking the rear then front. this mod was fairly easy and took me about 2 hours to complete after working out the wiring diagram.

Yep thanks it was the only thing I could think of that was cheaper then the center diff lock switch. Those are like 80 bucks on eBay for one
