i have a 1991 toy pickup 4x4 with crappy add front end. the problem is on the front diff the wiring going down to the diff is gone and when we replaced the clutch we broke the wiring coming out of the transfer case and now the 4 wheel drive doesn't work. i played with the wiring one the transfer case but it still doesn't work, is there a way to bypass the add and make it like a normal ifs. it already has manual hubs so that won't be a problem with the front end staying locked in.
