Default 1992 Mustang LX Neutral Safety Switch question

I just finished converting my 92 notchback to a 5.0 but Im having a problem with getting the car to start off the key. The harness and computer im using came from a manual but the transmission im running for now is an automatic. Does anyone know what I need to do to bypass and jump the neutral safety?

If its the neutral safety switch, you should be able to throw it in neutral and start it. If not, you can put a jumper wire between 2 of the wires. Dont remember which 2, but experiment and you will find which 2 without causing any harm.

try the plug at the transmission and reverse the jumper wire. its so you can run either a t-5 or AOD I dont remember which way it works like turdttop was saying but crawl under it and you will see the harness

To start a factory 5 speed the clutch needs to be depressed regardless of the car being in neutral. There is a switch on the clutch pedal for this. You'll need to make the computer think the clutch is depressed.

When putting a t5 in an aod car there were two wires at the transmission harness that had to be jumped. Not sure about going the other way.

White/purple(or pink) wire jumps to red/blue wire on the trans harness plug.
