Okay I am in the process of putting a stick in my LBZ. I found out I can splice the tan, and tan with white tracer wires in the allison harness together to make it think its in park and allow the truck to start.
If I wanted to get rid of the tcm totally and load a ZF O.S. into the truck I don't believe it will start without a signal from the clutch position sensor. I dont have that sensor hooked up obviously because the truck doesnt have that harness from the factory.
Anyone know which ECM pins need to be "grounded' or have a "signal" to allow start up??
Sure I could probably get away with keeping the alli tcm hooked up, but I'd have all sorts of annoying codes popping up
