wow that is awesome man. I plan on doing a Viper 791xv this summer in my 93. do you have a Email or something??

i suggest that this goes into techinfo

yes, but for simplicity and so others may benefit, ask your question here and i'll reply....

Good choice on alarm....
On my 92, i have the key with the "pellet" in it....yours similar?

If so, your in luck. This security system is by FAR the EASIEST to bypass. What do you need? Multimeter, trip to radioshack, and possibly a relay.

Here'* what you have to do:
Measure the resistance on the pellet (be very carefull not to touch the leads with your fingers, as it pay throw off the resistance). Write it down. Drive to radioshack, pickup a resistor. Wattage shouldent matter, but a 1/8 should be fine (if i remember, there was a post on this board concerning how to find the resistor pellet value). While at radioshack, you should also pickup "shrink tube". This stuff is the sh*t. There'* a variety pack with alot of different sizes, pick this up! When you wire the alarm, you slip this on the wire before wiring it....heat up the tubing...excellent seal.

Now you have the resistor. With the wiring bundle, there should be 2 THIN wires....i've only done this on a cadillac, but GM'* are GM'*. They may be in a little plastic casing.

At this point you have two options:

-Continue using security
-Remove it out of the equasion all together

I've always used the latter, as i also put in starter kill, so this feature was basically useless to me. If you are going to bypass is completely, cut both wires. Attach your multimeter to the wires running TO the key. They should read "1" or out of range. Put the key in, they should read the same as when you measured the key pellet the same. take a 2" piece of shrink wrap (about double diamater of resistor) and slide it onto one of the wires going to the engine (not side going to key). Wire up the resistor (soldering would be best...but if you can't...make sure that the resistor wont come lose), slide the shrink wrap over it, then heat. A lighter will work...BUT make sure to keep turning, or else it melts and smells! Tape it up all good, and hide it out of the way. System bypassed! and FYI: next key you need made, you don't even need the pellet in it!

If you wish to keep the system as is, heres the steps:
I'll call the two thin wires A and B. You will need a relay. Relay is explained above, and you will need to understand the basics.
tap into A (i suggest a red/blue butt plug) and run a short length of wire from it to one side of the resistor. Tap into B, and run a short length of wire to post 87. Take the other side of resistor to post 30. Here'* what it should look like:
A------resistor------30|relay|87--------B

Now while installing the starter, if it has a Acc3....here'* where to use it. Take that and attach it to 85 of the relay. It'* most likely going to be a - output. If it'* -, then attach 86 to a positive (fuse it!)..it only needs about 300mA (Assuming a bosch....i know that name'* hated, but it'* a standard for relays and i've NEVER had one fail), so a 1.5A fuse should work. If it'* a + output, then you attach other side to -. Get it?? good!


Now what happens here? When you go to start, 30 + 87 close, therefore mimicing putting a resister between wires A + B. It'* a bit of a pain, but it allows you to keep the security system. This is why i say just bypass the whole thing...no need to add another relay to complicate things. Good luck, and take your time - it will come out fine.

Fred, great detail and info..

Not that I have a need for a remote starter but I second this suggestion!

on the key pellet, i made one mistake.....
it SHOULD be as follows:
A + B are still two thin wires, but in this case we are going to cut A
take the side of A that goes tward the KEY, and hook that up to 87a
take the side of A that goes to the ENGINE, an hook that up to 30
tap into B, run a short wire to the one side of the resistor.
From the other side of the resistor, tun to 87.
Now it should look like this:
B-----|resistor|-----87|relay|30------A (engine)
A (key)------------87a|relay|

Now why is this the right way and my previous wrong?
In the previous, whenever you "closed" the relay, it would act like there was a resistor in place....BUT what happens when you would add a key? the resistance is different (formula escapes me now). In this case, 87a and 30 are NC (normall closed), which means while the relay is "off", then it'* as if you never modified the security system. When the relay is "on", it'* the same scenario as previous example, but a key in the ignition is ignored.

If someone wants to compile a FAQ with wiring/alarms/remote start, etc, i'll help you fill it out. Good luck - xFred
