Ok, i took the dash apart and removed the whole mess. Yes, it does cut power to the starter. It also had some wires running to a big horn. Their also seemed to have been a vibration sensitive module that might have tripped this. THe main module also had several small wires that tied into interior lights, which i supposed would trip the alarm also. Here are some pics of the unit. Oh yeah, it appears to be a GM piece, i am guessing dealer installed since zip ties and 2 sided tape were used. Oh yeah, is this worth anything...

It has the #'s 0-9, a # and * button. There is a blinking light at the bottom of this keypad also. After I switched the toggle switch that was under the dash, the car would no longer start. The light on the keypad is also blinking now, it never did that before. So I guess I somehow activated some sort of aftermarket alarm. I bought the car at an auction, so I dont know who the previous owner was to get help. Any ideas on how this thing is wired up? When I try cranking the car, the power to the starter is disabled. The car will not attempt to turn over. I know the tumbler is triggering like it should though because the power antenna starts to go down when I try cranking.
Also, when is the electric fan supposed to kick on? The temps have gotten up to 220 when the car is idling. When moving around in traffic, the temps are around 190-200. I never let it get over 220, I always shut it off before then. WHen I restart the car, the fan usually turns on, brings temps down to somewhere around 205 then shuts off. The temps rise again. Fan never kicks back on though. Is the car supposed to run hotter then 220??!!

I did not read all of the replies here so I am sorry if this has already been answered.

Goto this link and see if this is what you have BEFORE you let some "security expert" pull your Vette's engine computer apart.ProMinator
