I've got to do more research on the bypass. Are you saying the factory locker switch is disabled or that if you want to individually lock F/R you use the toggle switches and if you want to lock both you could still use the factory switch? I know its so you can lock them in 4Hi.
My simple switch wiring controls the two locker compressors independently and uses none of the factory wiring or the switch which is now dead. It was a simple project, like wiring up two light bulbs (the compressors) with an on-off switch with a fuse to protect them.
. I have been trying to keep it stock looking. I have already modified my dash to have the additional 3 switches where the ash tray was. I have been thinking that I could get one of the 3 switch plates from an XJ from The Bay and fab a metal plate that would hold the auxiliary 3 switch panel below my switches, using the factory screw locations that hold my original switch panel in place. The metal bracket could extend out from behind the dark grey dash panel, between the dark and light dash panels. It would reside left of center of the console that is fwd of the shifter. I would probably remove the power outlets from the XJ panel as I really don't need more than two.
