Default EM1 alarm system removal

Hello all I am needing some help getting the rats nest under my dash figured out... I have no idea what kind of alarm system it had, but it has never worked in the 8 years that I have owned the car. Today I was working under the dash on my cruise control wiring and decided today was the day to pull all the alarm system wiring out of the car. Now I have got a bunch of the wiring out already but there's still some more that I'm not sure if its part of the alarm or if its factory. Here's a couple pics of what I'm dealing with.

Ok I have done more cutting and splicing wires. I'm getting to the end now! I have 3 plug-ins that I need help with. As it sits right now, the car won't crank. Fuel pump primes and everything comes on when I turn the key on but it won't crank

Those excessively long wires that don't have any sleeving or tape are aftermarket. The starter is activated by a large wire from the key switch, black with a white stripe. Aftermarket alarms usually cut that wire and put a relay in line to prevent starting if the alarm is triggered. Also note that the stock system has a clutch switch / relay to interlock the starter on a manual or a neutral switch on the shift lever if automatic.

Good info. Thank you for that. I eliminated all those wires and spliced them back together. It is a manual trans and the car has always started without pushing in the clutch. Maybe my clutch switch is bad? How do I test it? I tried bump starting the car and it fired right up and runs good. Just can't get the starter to engage

Someone has modified wiring to bypass the interlock then because if it were truly stock, you would always have to push in the clutch.

Ok guys I got it fixed! Turned out to be a loose crimp connector buried under the dash. Now everything works as it should including the clutch safety switch. Now I gotta get back to my original problem of the cruise control!

Make sure all your connections are secured. Ditch those crappy crimp connectors and solder instead.
