Guys I am not too experinced with Remote starters but have the basics. In regards to Bypassing VATS on a GM 1995 Lesabre Buick. Could someone tell me if I should use the resistor and relay method or buy a BYpAss module. Someone has mentioned in the forums that if the resistor breakes or the connection goes bad that the car will stop running. So that would mean if I was on the HIGHway I would be dead!!!! If I am mistaken could somone please correct me. Please advise. Thanks ASab16 :errr:

It is true that may happen i would use a bypass for the vats.

remember to check all your wires with a dmm not a test light!!

i'd check out the bypass modules from bypasskits.com. I know i used the plxr module to bypass the vats system and it worked great. I even got it to work on a 94 olds 98, the people that made the bypasskit didn't even know if it'd work on a 94, so it was a test part for both of us.

Don't worry about driving on the highway. Its a starter kill not an igntion kill. When, ( I mean if...) it breaks , you just won't be able to start the car.

Ok guys quick question, if I use the resistor method.................the relay hook up are as follows......30=passkey wire computer side...................................85=to grnd out when running............................. 87=passkey wire key side......................87........resistor............ now 87= ignition.............. question is 87=ignition but ignition of what......................remote starter module or ignition wire @ ignition module.. Oh and the bypass module how does it exactly work......I mean hows the hook up on it.

Thanx Derek123..... 4 the reply......That was my guess, but others in 12volt have mentioned the fuel pump getting cutt off.... So its hard now....since people are contradicting...... So derek123 basically the key with resistor is only checked once during startup thats it.......if the key was taken of the cylinder once the car fired up that would make no diff theroiticaly speaking. Thanks everyone 4 replying.....and please continue to reply...... Lastly I have took a peak on my 95 Lesabre Buick.........I see a Orange tube and a Black tube....in the steering column when I did the tilt steering.......the black tube is rather thin diameter of a penny and the orange is the diamter of a quater. Now I have a Black tube and Orange tube.....both where are referd to in Bypassing VATS..... which one is the VATS wires Black small tube or the bigger orange tube...... Thanks everyone....

The easy way to test is start it with the key, let it run for 15 sec. and cut your vats wire(s).... see if the car stalls or not.

The VATS wires will be encased in an orange loom about 1/8" in diameter. Follow this wire to a 2 pin connector (usually to the left of the column, under the dash) and you will see 2 VERY SMALL, white wires coming out of the orange loom and into the one side of the connector. The color and size of the wires will change on the other side of this connector and this is the easiest location to tap the wires. I have ALWAYS used the relay and resistor method and it has NEVER failed me. Just make sure that you get the resistance as close as you can and solder ALL connections so that you will not have problems in the future.

THank 4 the reply guys!!!! Just to confirm.........The VATS...............Once the car has started does it continue to check for resistence from the key chip.................and if the resistence is not there will the car stop running......or is it just a one time check during startup?

Are the VATS wire isololated or budled together with otther wires................secondly on the relay 87 is suppose to go to a IGNITION.........could somone go into detail and tell me ignition of what......the remote starter.........the ignition power of the car........detailed instructions would be nice. Thanks

its the same wire..ign on the RS goes to ign in the car

So just to confirm according the VATS BY PASS module Resistor method using RELAY.......I take the 87 from the relay and hook it up to the IGN of the R.S unfused............... Oh and guys lastly any specific wire guages to use when doing the VATS?? lastly are the VATS wires isolated in the orange and Black tubing or budled together with other wires?????

86: Ignition (12+)
85: Remote Start Output (12-)
Then strip one of the VATS wires (#1) and cut the other (#2)
87: Resistor and then to stripped VATS wire (#1)
87a: Key side, cut VATS wire (#2)
30: ECM side, cut VATS wire (#2)
It doesn't matter what gauge wire you use.
The VATS orange wire loom will run along with all the other wires that go to the column and then will split off on their own.

if youre not worried about someone stealing your car, then a quick fix would be to read the resistance of your key chip using a DMM, cut both VATS wires, and install a resistor of the same value as the key, looping the two wires back to the ECM side. This permanently defeats the VATS in your car. This also makes it cheap to acquire replacement keys as there is no need to have them cut at the dealership with a chip.

Thanks Guys.....I found a Orange wire.....like siamese twins....its actually 2 wires but looks like one wire. The wire looks similar to a IDE Cable in a computer but smaller. It goes into the IGN harness and when going into the harness u see it look white. Just before entering. IS THIS VATS????

The IDE looking cable does not consist of the VATS wires...but the VATS orange wire will run along side it and then change directions of the IDE looking cable once it goes under the dash. ...and yes, there is actually two very small white wires inside of the orange wire...
