1996 Ford Ranger clutch bypass

Do a simple test.  take out your dmm and measure voltage on each wire during CRANK with the clutch in.  You'll find that one of them goes to +12V when starting only.  Now, with the truck safely restrained (and in neutral), temporarily put +12V on that wire, and try cranking WITHOUT the clutch in.  You'll find it cranks.

So...you need to apply +12V only on crank to that wire to bypass it.  Using a relay, use +12V crank signal to both power the coil and use as output, and use the rmt starters ground-out-when-running to ground the coil.  This essentially allows crank signal to reach that wire ONLY when remote starting.  If you had just applied +12V on crank, it would have permanently disabled the safety.

As always, use a DMM to test EACH wire and be extra sure of whats going on.  Don't just take my word for it (this is my disclaimer!)
