Does my '90 have theft deterrent installed?

[tashirosgt]

I'm not the original owner of my 1990 Corolla 4A-FE with A/T. What's an easy way to tell if it has the OEM "theft deterrent" system installed? Is there supposed to be any thing obvious on the dash? What about wires I could look for in the engine compartment?

What do such systems do? Do they disable the whole electrical system? Or do they merely disable the starter or some subsystem?

probably not, they werent general equipment during the late 80's.
Disable starter or fuel pump/ignition.

I don't think it has any deterrents.

If you want a simple kill switch, theres two red wires going to the tranny. Put a switch on it. They're basically neutral safety wires. Car won't start if the tranny's not in P or N. Put a switch in, can't start it unless it's in P or N with the switch on!

OEM theft deterrent was probably available in 1990 since the 1990 service manual shows that option and gives a wiring diagram for it. I'm just looking for an easy way to tell if the car has it without deciphering the wiring diagram.

I don't want a theft deterrent system. I just want to make sure it isn't the cause of a mysterious problem I have with my starter not working.

My 92 came with it. The dash had a security light. The theft detterent would go crazy on me sometimes so I took and just snipped all the cables. Supposedly the computer for the theft det is under the pass side kick panel. I never pulled it out, just found a wiring diagram and snipped the cables.
