1999 gmc safari newb viper5704

Hello all my new 12 volt friend's my name is barry. I recently purchased a viper 5704 remote start/alarm. i also purchased 508d motion sensor & 506t audio glass break sensor to go along with my install. I Plan to install it myself, in my 99 gmc safari. I certainly consider myself an advance diyer with lots engine swaps, turbo charged engine tuning & customizing of many makes. That being said I have never installed a alarm/remote start (here I would like to install both) but the included instructions are a bit vague. I know I have to either bypass the passlock with a resistor.. or buy a module, xpresskit? And is their any benefit installing a xpresskit module over the resistor bypass? Door lock control? maybe other features?. And beyond that I'm kinda lost which wire goes where on the vehicle? and which wire does what on the viper? Maybe I'm overwhelming myself any help would be greatly appreciated. I would really like to do this install myself with the help of others. I really enjoy learning If the resources are available. Thank's

Hi Barry!  Welcome to the 12 Volt Forum.  Being familiar with cars and willing to research and learn is

a good thing.  With that attitude, some basic 12V tools and a weekend off you will be able to install theViper alarm system.

Research and planning will be the most important part of the job.  While the install sheet included with

your Viper is brief, cryptic and vague, you can locate a more complete manual in the Downloads section.Compare the guide to your physical system, as Viper has changed some connectors around on thenewer units.

Next download all the wire guide info you can find.  Print it out, compare it, note any differences and

make up a "to - from" cheat sheet to use during the install.  Here are some wire guide sources :Here is a link to Bulldog Security :  http://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.aspHere is a link to Ready Remote :  http://www.readyremote.com/main.aspHere is a link to AudioVox :  http://techservices.audiovox.com/AccessRequest.aspx    Sign-up & info is free.This site will have wire info in the Vehicle Wiring section.  You can also do a search function for prior poststhat will give you some insights to problems encountered on your vehicle.  As you probably know, Chevrolethas twin to your Safari, so search on it, too.

Post your proposed wire connections for forum member review / input and ask any questions you have.

The easy part will be taking the dash apart and making all the connections.

two questions h1/4 park light isolation I don't understand its purpose but I'm pretty sure it's not needed on my vehicle. & h1/5 parking light output this just gets wired directly (no relay) to the vehicle? I used 》to symbolize vehicle wire side H1/1 red +12vdc constant input 》red or RED / white @ ignition switch. H1/2 black -chassis ground ok H1/3 Brown +siren output ok H1/4 WHITE/ Brown parking light isolation. Pin 87a of onboard relay (not used) H1/5 white +Parking light output.》+brown @headlight switch or (same Brown)2 other possible know locations. H1/6 orange -500ma GWA output. 》 starter kill relay and or sensor ground with diode(s)

All right!     Good work on the H1 harness.  Just a few updates.

Correct, the H1/4 WHITE/ Brown wire won't be necessary on your Safari.  Yes, the H1/5 White wire will be directly

connected to the Brown (+) Parking Light wire at the Headlight switch.  Just make sure the Viper's internal jumper/fuse is set to (+).

The H1/6 Orange wire won't be necessary for Starter Kill.  The Viper has a built-in relay for the H3/4 and

H3/5 wires that performs this function.  These wires can also do Anti-Grind, see programming Menu 3, Item 13 for more info.   Typical uses for H1/6 are window roll-up, etc. 

As a note on the 5704 install guide, download the older 5701 install guide.  There are some differences,

especially with the wire / harness locations, but it provides a more detailed reference on wire functionand programming options that you can correlate to your newer 5704 system.

The next area of concern is the Passlock2 and the power door locks.  As you mentioned, there are

bypass modules available for the Passlock2 bypass.  They will make the install easier but do costmore than a couple of relays and a resistor.  Either will work well.  Here is a nice guide for doing thePasslock2 bypass with relays from Audiovox :  http://documents.audiovox.com/700054.pdf   To dothis properly, you will need a Digital Multi Meter and a variety of resistors ( or a handy RadioShack ). One of the better bypass module alternatives is the iDatalink ADS TBSL PL.   They can be found online for under $40.  They are very easy to install and program and very reliable.  Here is a link to the iDatalinkWEB site to look-up and get the ADS TBSL PL install guide :      http://www.idatalink.com/support

For the door locks, you need to convert the Vipers (-) lock outputs to a (+) pulse that the Safari

needs.  There are diagrams of this in the Door Locks section.  Another way is to use the DEI 451MDoor Lock Module.  It does the same conversion, but in a pre-made, neater package.  These are also available online and go for less that $9.  The 451M install guide is available in the Downloads Section.

I bypassed the passlock 2 system using a 1k ohm resistor only. will the remote start work this way or do I need to introduce the relays and resistor? from what i could gather the relays & resistor only need to be added to retain the passlock functionality by only momentarily bypassing passlock during remote starts so when the viper is disarmed passlock would still function. So I was thinking the resistor Just tricks the passlock into seeing that resistance even when the key is Absent. As If the key was always in the ignition. sorry for overcomplicating my responses. Im just trying to be thorough. I like to have a understanding of things rather than just saying oh well it works.

If you have already bypassed the Passlock2 immobilizer with a 1K ohm resistor ( by cutting the Yellow

Passlock wire and soldering the resistor between the Yellow ( BCM side ) and the ORANGE / Black reference wire, and then doing the 30 minute relearn process ), there is no need for any sort of bypasswith the Viper 5704.   You have disabled the vehicles immobilizer system all the time. 

This isn't uncommon, as the Passlock internals of the ignition switch are known for this issue and the

original resistance value it supplied to the BCM is incorrect causing an engine no-start condition and putting the vehicle into Passlock Tamper Mode.  The good news is that by installing the Viper, you areadding an alarm system with a Starter Kill circuit to prevent theft and make-up for the disabled Passlock2 system.
