The 2 wires on the first pic that are red blue you need to follow them up under the dash. That short 2 wire harness should plug into 2 Red/blue wires under the dash. Unplug the 2 wire harness and plug the 2 wires under the dash into each other. This will by-pass the neutral safety switch.

I wire my neutral safety switch wires thru a toggle switch under the dash. It's my low tech security system

Thanks for all the Help on this issue I 'm going to do what BillyC did with the doing the security system I like that Thank's

Go to a boneyard and find an older pickup truck.  Grab the clucth switch (neutral switch) and it's bracket and install it on your Stang.  Stright forward and safe.  Don't just hot wire it. Too dangerous.

I spoke incorrectly.  The clutch safety switch I found was on a mid 90's truck. They all have one. Visit your local boneyard and peek under the dash near the clutch pedal.  Any make should do.  You will have to fabricate a bracket to hold it, but it's an easy set up.

Just get a momentary contact switch from NAPA for around $5.  Beats a trip junk yarding, unless you just like going for the relaxation.  You want a normally ON switch, and rig it so the clutch pedal depresses the switch in the static position of the pedal.  When the pedal is depressed, it lets the switch return to its normal unactivated ON position.

Or just do like us old farts do and remember to depress the clutch pedal before you hit the key.

I almost always remember to put the tranny in neutral before I "far-it". Hold-over-habit from truck driving school.
