I'm in the process of installing my lowering harness, everything is almost hooked up I'm just missing the oil pressure switch and the plug the goes on the alternator. I'm stuck for right now. I'm using a auto tranny lower harness.

What's the white cable with the Grey plug?

EDIT: nevermind...thought it was the starter signal wire, but it looks to be to far away from the starter

Bump anyone?

Alternator power feed to the fusebox. The style changed slightly on some models. Some use a ring terminal on that wire to connect straight to the fusebox instead of using that grey connector.

It is important to take the extra steps and wire up the neutral position sensor when doing the auto to manual conversion. Failure to do so will result in an engine stumble/RPM drop whenever you lift off the throttle after a pull. The ECU will cut fuel injector pulsewidth and lean out the engine momentarily if it does not see the neutral switch activated.

The auto and manual cars used different chassis harnesses, therefore you cannot just swap the transmission harness and assume the neutral sensor will work. You have to wire neutral separately.
