The 90 ecm going into the car will be needing the vats signal anyways and being the top will be off the car a lot. So figure vats will give me a little peace of mind.
VATS in a 1982? How hard would it be to wire up?

I understand the problems revolved around the key or contacts in the pellet ....
and so was eliminated by aftermarket programmers all the time....it maybe was done already in your donor car.....
I have a custom AT system in my car, I took the voltage feeding the computer's 5 volt regulator and interrupted it, if you look at the wiring diagram you will see how that works....and so I buried a old garage door receiver under the dash....hit a garage door remote button to start car, it triggers a latch relay...self energizing.....so this remote sets in the car map pocket, I turn on the key, then hit the remote, then start the car, been that way for some 16 years now, so not any issue with me, it's automatic....even when observed, I doubt anyone can detect what I did....but engine will not fire of course...neither will FP activate....
:nuts:
OH, when I botched the repaint some couple years ago, I shaved/removed the door lock cylinders, in fact my doors can not BE locked, being a rag top, why bother??

Measure the resistance of the chip in your key. Then take your meter to Radio Shack and get a resistor or series of resistors to solder together to measure the same as the resistance of the chip in your key. Finally use the resistors to complete the VATS circuit. The computer will always see the resistance required to disable the security system that way.
I have done this to tons of GM vehicles to disable the security system and never had a problem.

Actually, I like VATS so I want to make it full functional. I replace my tumbler sets every couple years and have never had a no start problem.

yes post a picture of the diagram. Do you know if a 90 corvette ecm also looks for 50hz signal?

Now just got to find a key and matching decoder box

Will the pass key tumbler fit in my column?

I have been using 1227730 in my '72 vette.....it don't take any decoder module it's wired like a '91 firebird V8.....aftermarket chip....

Your chip has VATS disabled, he wants to keep it.

I know, I offered suggestion as to what I did in place of the troublesome VATS system, it has a poor reliability reputation, I had it bypassed in the chip on my '87, :surrender: and of course on the basic TPI setup on the '72 now....

My 97 camaro has vats and it has never been a problem, but I replace my tumbler set which is where the heart of the problems are every 2-3 years and I have never once had a issue. What 60.00 in 2-3 years...

So you are putting forth the concept of installing a trouble prone stock system into a early vette so the VATS works as designed, I never did consider it for my '72, and it has a '78+ shark TT column installed in it....
so would be the same as that '82? in planning here....why bust a nut over it when other options like I outlined above work much better, as there is NO auto thief going to tear the entire car apart of steal it....hell I leave the keys IN it at cruise nights....knowing full well it not going anywhere....

Yeah but like you live in florida and california is just a bit different. Vats may not stop them but it will certainly slow them down for a easy 2 hours.
Part of the effectiveness of VATS is that thieves knew which cars had it.
If you want to keep the disable feature though you could just skip the chip key and use a VATS bypass module. It's just a 30 or 50hz generator you can plug in somewhere in the car. Pretty easy to make yourself too. You would have to bypass the starter disable though.
But if you're going to do that, you might as well just install a hidden kill switch.

Guys can find/feel/see a 'hidden kill switch'.....it has to be located so the driver can reach the damn thing easy.....on another rag top I had years ago, I put in a double latch relay setup, key and LIGHTS on, push buttone one, latch relay one, push button two, latch relay two....only THEN would the car start.....
like I said, being devious is more important than any factory setup.....
they literally have to tear my car apart to find it, and even then NONE OF THE COMPUTER WIRING FOLLOWS STOCK COLOR CODES.....for a reason....
:bump::clobbered: they CAN steal it, but they need a hook, not driving it....
:club:
Unless you can swap the key switch from the 90 into the 82, aren't you going to have to adapt the C4 column to the C3?
