I am doing a old GM car that has VATS I am not familar with how to bypass this permenately.

Do I cut the 2 white wires in half then connect the ends going to the VATS unit togetther with a resistor in between?

Also the value of the key was 681 wil a 663 resistor be close enough?

Thanks

Yes that is how you permanently bypass the VATS system. The 663 ohm resistor is fine to use. Install the resistor across the cut ends of the wires that go to the car and not to the key cylinder.

Thanks for the info I have the directed version of theat document.

I am looking to bypass the system permenetly.

Are there any draw backs to this?

Umm, the Vats will not work and be rendered useless. You sould just bypass it with the use of a resistor and relay and not permenantly disable it. It will bypass it only during RS that way.

I guess if you have someone work on the car that is unaware. Or you sell the car.
Also, use a good grade resistor. Some resistors change there value when it is cold.............

I just did this to a '94 Caddy that had problems with the VATS through the ign switch due to age. I read the key, put the resistor just like you said, pulled the pellets out of the keys and it's worked fine ever since. The customer is fully aware it's permanenlty bypassed now. Car is so bad, next stop is the boneyard anyway. Anyone who steals it would be a complete moron. A thief would never want to be seen in this thing, it's so bad! posted_image

The problem with any car that has VATS is that over time the 2 wires that run to the ign. lock start to fray in the column up near the back of the ignition lock. When this happens they ground out or they contact each other and cause the vehicle not to start.

A little from column A, a little from column B.

Ok thanks for all the input I did the car today works perfectly.

One problem when you remote start the car the "traction off" light comes on.

It remains on while you drive it.

But if u start it with key it works fine no light.

What could this be?

Car is a 1999 Oldsmobile 88LS

Thanks
