So there's a few threads on how the wiring is on these or how to put a manual switch, but I couldn't find exactly what I was looking for. Everyone has 3 wire plugs and a vacuume sensor for the Lockout to engage/disengage blah blah blah.
I'm running an 83 GMC originally k1500 with 6.2 and a 700r4 that is not the original. The truck only has 2 wires to the harness, one from the brake switch and another from what I belive is a throttle position sensor. My Lockout was always funky it seemed to me locking/unlocking at odd times and I put another trans in (broken internals) and it does the same.
Being a gutless diesel with 4.10 gears that often tows a truck I wanted to control this a little better.
Manual Lockup on the highway for milage, manualy unlock while towing for power, and around town driving.
I found some and also drew up some diagrams if I were to put a solenoid on the brakes but the brakes or throttle sensor could override it (more concerned of the throttle sensor)
I've read putting power to the hot wire will engage it in 4th and a switch on the ground wire for 3rd but didn't belive/understand how that would work. See other diagram.
My questions are,
If I apply power what does the Lockout do in any gear?
And
If I cut ground what does it do?
