4JG2 Neutral Safety or TCM starting issues

Post by jaameswright »

Anyone have any insight into removal of needs of the TCM in a manual 94' 4JG2 Bighorn? The car was originally automatic, however was convertee through a donor car, but the silver transmission position sensor module was left connected. I was wondering if there was a way to remove this and allow my car to still start, because if I unplug it, the ECU thinks its in gear and wont start.

Any insight would be helpful.
TIA

Its just bridging 2 pins but you will have to study the wiring diagrams to work it out

Looked further into this, how much of the TCM is actually required in the manual - want to completely de-clutter the car top to bottom just to play around and tinker and it seems theres a lot of TCM functionality that doesn't apply to the MUA. What could I look at doing to remove all the extra shit
