93 Alarm removal (step by step w/pics)

[Rideold]

This was a super helpful thread. I removed the alarm and remote start from my 92 on Friday. I had an intermittent no-start that turned into a permanent no-start. I was getting ready to dive into the NSS because early on I got it started by shifting into neutral. That worked once. Then I found out the brand new battery I had put in last August was defective. I was hoping the warranty replacement would solve things. Not a chance. After full removal of the alarm and remote start she started right up without a hitch....even after sitting for a few months while I waited for the weather to warm up (I don't have a garage). I've been driving it all over town for the last few days and haven't had a problem.

This is long and pic heavy, so i apologize, but not really. There are so many FAQ's on here that i have used i thought I'd take my time and document this to help others.

Reason i did this was something is draining my battery, not sure if the stupid blinky light was enough, but now that its out, time will tell if i solved the problem.. (i kind of doubt it)

The system in question is :

Step 1. Disconnect battery . Unplug system brainbox. Remove the plastic kick panel, the dead pedal, and i took out the drivers seat to make things easier and to give me space to work. Pull up the carpet to reveal the alarm harness and where it flows into the factory harness.

Follow harness cutting the zipties that hold all the alarm wiring to the factory wiring.

Step 2. Pull out the wiring from the little hole behind the kick panel. You will find a 4pin, and an 8pin connector.

Unplug the 8 pin connectors. it will be obvious which go to the alarm and which sides are the factoy and will stay. the wires are not that long, don't pull to hard.

Put the 2 ends together that are the factory side.
Next, the 4pin connector. Do the same. unplug the alarm side, and plug back together the factory side.

Step 2. Locate the 11pin connector a little further back twards the firewall in that same kickpanel.

Again, unplug the alarm side, and plug back together the factory side.

to be continued....

Is there any chance you still have these pictures? They are not showing up anymore.

I was about to remove it. When I just repaired the circuit board. The micro relay that turns the alarm ignition relay ground on and off seems to be the main fault for most of these. The failure is from constant cranking or short in starter. The security module still works and the remote will still work with the micro relay failure. The lower left 2 pins on the alarm brain are the 2 circuits on the board that fail. The wires are ( Blue wire red dash) (Black wire blue stripe red Dash) the Blue wire goes to the ground pin on the relay under the dash that is connected to the security alarm switch.

Thank you! The alarm in my 94 was going off randomly, so it was time to remove it. Like some others in this thread, I didn't have a remote and didn't realize the truck even had an alarm until it started going off in the middle of the night.

Post #36 is super helpful (thank you jdogg and SnowroxKT for reposting)! I was able to pull the wiring without removing the front seat, but with all of the contortions to get under the dash to get at the last few plugs, it probably would have been faster and easier on my back to just remove the seat to have more room.
