So after the conversion, I'm wonder if most people just pull the Transmission ECU or leave it in. I unplugged it so I no longer get the blinking HOLD light. I'm thinking the only necessary thing effected is the brake lights which I should be able to rewire. Am I missing anything? Is it necessary for anything else?
Thanks,

Re: Transmission ECU after 5 speed conversion.
I believe they are the same physical unit, just auto ECM has 1 extra plug. I think you can just keep the stock ECM. It runs the engine and tranny seperately.
Or just pull the hold bulb

Re: Transmission ECU after 5 speed conversion.
Well I dont know about the other models but the 93 GS with auto trans had a seperate ECU for the trans. Which I've already disconnected, the car seems to run fine, I was curious about about the electrical connectors going to the seatbelts are those just for the annoying seatbelt warning bell and lights?

Re: Transmission ECU after 5 speed conversion.
I noticed that too on my '92 4cyl. There is an extra plug just for the auto tranny which I assume controls when the transmission shifts and such (as part of it goes to the throttle body).
I was actually planning to swap the inside wiring harness from a manual mx3, but I don't see why having that disconnected would hurt anything.
