Thread: Viper 5704 Bypass Module for 97 GTP

Hey guys so I decided to upgrade my alarm system on my 97 GTP coupe and was wanting to know which bypass module I would need. Any help will be highly appreciated thank you

Any help will be appreciated

97's don't have an immobilizer. So not getting a bypass would be your best option.

97's should still have VATS. Does your key have a little chip in it? If so.. put an ohm meter to each side of the resistor and see what reading it is.

Then do what I did. Solder a resistor of the correct value to the BCM where it needs the signal and unplug the connector to the dash for VATS. Put in alarm system and smile. Cause no one is going to believe you bypassed the theft deterrent when you put in a better theft deterrent.

I know for a fact that my 97 does not have an immobilizer or the little resistor in the key.

I was wondering the same thing a few months ago when I was about to get my viper installed.

I'm thinking GM saved more money on the GP than the chevette by leaving off key things/features.

But wouldn't their be a problem when you go and start the car with the key, because the 2 resistors(the one in the key and the one you soldered to the bcm) together would create too high of a resistance.

or would it be okay because you unplugged the connector?

I said unplug the wire to the dash...meant column.

Once that's unplugged, they system can't read the unplugged side of the connector (aka key). With that said..it's only reading the one soldered in resistor.

You are correct about the wrong resistance if you left it connected.

Thanks for the help , and the key does not have a chip. Do you guys think it would be an easy install or should I just take it to a professional . Best Buy quoted me $200 plus $60 if it needs resistor , do you guys think that is a good price.

Okay this is whats gonna happen.

If you bought the remote starter at bestbuy installation is included in the price of the starter.
They're going to tell you that you need the immobilizer, you can tell them that you don't need it but they're probably gonna install it anyway. They do this because if they were to take someones word for it and they ended up needing an immobilizer, it would take the tech guy twice as long to do it because he would have to go back and install the immobilizer.

That's what they guy who installed mine did. He installed it with it. Then disconnected it, and when it worked with out it he removed it.

Just make sure you're not paying for it in the end.

Well...directions for a Viper are not really out there. You'll need to search for maybe 2-3 wires if you are familiar with alarm systems. Overall though it's pretty easy. I did mine, took half a day.

Bill - I am familiar with electronics but have never installed an alarm i will be greatly grateful if you could help out in the process !

I purchased the alarm online , I called Best Buy just to get a quote

Ok, go hit up the12volt.com and find the section on wiring for doing an alarm/starter. Print that out.
If you have the vehicle schematics, have those handy.
Then take the single sheet from the viper and start mapping things out. Pay attention to +/- that the alarm expects vs the wiring on the schematic.

Holler with what you need a hand on and I'll likely dig out my box (I think I left all my notes in it)

Do you own these tools?:

DVOM
Soldering iron
Typical hand tools

Are you familiar with electronics, and the proper way to test automotive circuits?

Im pretty familiar with electronics and I do own hand tools and soldering iron, I will get a DVOM since I dont own one and get tired of having to ask to borrow one from my buddy
