I'm trying to install a Crime Guard alarm in my '89 T/A. This alarm comes with Quick interconnect Wiring harnesses (for the main wiring harness w/the ignition, etc and a door lock harness) -- so you don't have to cut any wires. The only probelm is, I've looked underneath the dash and can't find the connectors they're supposed to plug into.
As usual, the shop manual is pretty worthless and the info from Crutchfield (where I bought it) is vague.
Can anyone tell me where exactly these connectors are? Thanks.

 

I actually haven't yet done any security work on a thirdgen, so forgive me if I can't give you the exact answer you're looking for, but I'll try to at least get you started.

The wires you're looking for are going to be very thick, like at least half as thick as a cigarette. They're going to be red, pink, orange, and brown, and either a yellow or a purple.

I'm pretty sure these wires to unplug from the steering column, and that plug is at the TOP of the column. If you look, the entire steering column is held up in place by two large nuts, which are very easy to remove. Once you undo them, you can drop the column down at least several inches........ you may neet to reposition some of the wiring so it's not in your way, or you might even need to remove a couple of other small things...but it's not a big deal.

My guess is that once you drop the column, you'll be able to see the plug.

 

Thanks. You were right. I dropped the column (which sounds more difficult than it is) and there it was. The plug WAS a little difficult to get to.
The really annoying thing was that once everything was installed the alarm didn't work right. It turned out that one of the connectors on the pre-assembled harness was bad. And this connector was on the plug that was plugged into the top of the steering column.
So I wasn't going to push my luck and drop the thing again, so I just spliced that wire.
So all and all, I would say that installing the alarm myself was a bigger pain that I thought it would be. There are a lot of things to do and it all just take a lot of time. But you do get the job done right. I routed the wires neatly and kept the hole-drilling to a minimum (I only had to drill 1 hole.) I do recommend using one of the CrimeGuard wiring harnesses (even tho I happened to get a bad one). I never liked the idea of cutting into all my wires.
It is much easier to pay someone to do it for you, but I never really trusted the alarm installation bozos -- I just assumed they would butcher my car.
Hey, and my alarm actually works!!
