So I have a 1994 4L60e transmission and ecm. Been running it for awhile now with a np241c from a suburban for pass drop. It only has the 2 prong switch for the 4wd indicator light. What have people done for the 4lo signal to the ecm to adjust for the gearing change? Easiest is obviously a toggle switch. I know the 3 prong switch doesn't fit in the older 241s. My thought is something in the floor shifter that closes the circuit when moved into 4lo position. Anyone already do this so I have some guidance or do I need to engineer this from scratch?
