Alright well to start off This is sort of a MKIII/JZ thread. This involves the MKIII dash harness, but may also tie into the JZa70 harness.

I know there are threads on how to Splice the Neutral Safety so the car thinks it is in park all the time. My harness is all ready to go, but it will not start the starter and I am sure the problem is because I have yet to splice a wire to make this function work. What wire can I " trick " the car into thinking it is in park all the time to make this work. I hope I am explaining myself correctly, and I am sorry if I am not doing that great of a job.

Also please remember I keep hearing that that Auto harness people use to splice two wires a black and white wire off the transmission plug. I am using a JZA70 5-speed harness, I am trying to splice into the dash wires to get the car to start. This thread is 100% different then most because of this issue I am having. I would like to add the car is a '91 Turbo Auto from the factory. A 1JZ swap is what I am installing, thank you.


Thank you,
