k i have a 93 rx7 bought as a shell everything just got completed now car wont crank. Cant find the harness comming from ecu to neutral saftey switch. try'd looping the security box by driver side kick pannel. any help would be greatly appreciated pictures would help thanks

 

This is a simple circuit. Basically the signal starts at the ignition switch, goes to the starter cut relay, then the neutral safety switch, then the starter solenoid.

The starter cut relay is in the driver's side footwell and is controlled by the security system. Jump the two FAT wires in this connector together to bypass the relay and any potential interference from the security system.

The clutch has two switches. The neutral safety switch is the one at the bottom of the pedal stroke, not the top and is not connected to the ECU.

 

Ask GoodfellaFD3S. he knows all about this sort of stuff.

 

are you ok? all i noticed was (PLEASE HELP). I thought you were dying or something.
now i see your not, id better go..

 

Anyways for the guys who tried to help thanks alot i found out the problem the starter wire going to the fuse box got cut somehow thanks anyways
