In the 1701G Manual it states to not interupt the Can Bus Wire or disconnect the battery (because of throwing codes) How do i hook this wire up do you strip the insulation back and solder to it. Or Should i just disconnect the battery? Its a 2007 Avalanche Thanks

yep, just strip it back and solder and tape well, you should be fine. It does say in the manual to do your soldering as far away from the OBDII connector as possible. I wonder if that's just so you don't heat the wire up too much and melt the pins on the plug holding the wire in or if there's a more sinister reason ------------- Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

yes....strip the insulation and solder it just like you said. Don't disconnect the battery, and do you have a 556u also! I not 100 percent certain, but i remember doing one about a year and a half ago and i needed a 556u also. What I'm not sure of is if I used a 1701g or a 1700g. Pretty certain I used a 1701g. It'll tell you in the manual where it lists the compatible vehicles. And the customer will lose a key! Oh. and i'm assuming you're doing a remote start......right? ------------- ...half of the truth can be worse than a lie. <----Roger Russell said that..

Yes a Viper 5900. And That Compatiably CHart says some Avalanches may need it all i have is the 1701g and the 5900. I hope i dont need the 556u. There was 2 verisons of the 1701g i think. So maybe the new one you dont need it. Also i dont no why you would need it on the avalache but not on the tahoe or any other trucks.....

On xpresskits.com it doesnt list the 556u it show a PKUGM2X but it looks like the 1701g should be all i need

Where can i find a 9.6k and a 6.3k Resistor @ in town. I went to radio shack but they dont carry them any ideas?

Build the resistor values out of other resistors. The value will change using two or more in series or parallel. Heck, i've used 6 at a time to get the value i need. You don't need to be on the money, 5% off will work fine. Shame you have the 1701g, there are much easier modules on the market to use. Idatalink mods don't need the resisitors at all.....

I was going to suggest picking up an Idatalink ADS-DL or ADS-ALCA you don't need to use any relays or resistors... makes for a cleaner install, easier to trouble shoot if need be and saves you at least an hour of install time..... ------------- Kevin Gerry

does the wattage on the resistors matter 1/2 watt?
Posted By: kgerry
Date Posted: September 17, 2008 at 5:30 PM
1/2 or 1/4 watt will be fine

I used these on the 08 Silverado I just did.

Worked great, just dial in the exact resistance you need, no mixing and matching random resistors.

on the 1701g Diagram it says there is a 2nd Accessory output on the Remote start relays. I only have one and its orange (DEI Remote Start). Is this the same as the 2nd Igniton PK/Wh SO do they mean 2nd igniton from remotre start to the 6.3k resistor to the pk/blk wire of the Key Cylinder? Thanks

OK i guess i found the -2nd accessory output its on the Small gage harness off the remote start relays. does this need to go to a realay or straight to the Resistors and to the pk/blk wire. Now that im looking at it it looks like the diagram showsit as a +2nd accessory. so now im really getting confused?

most DEI units have the ability to program the Pink/white wire as either 2nd IGN or as 2nd ACC depending on what you need... when you go into the programming menu it allows you to select whether it will act as an IGN or ACC.....

No you don't need a relay for negative park lights.

Ok i have everthing working now. Except when you arm it then remote start it it will keep tring to lock the doors evey 10 or so seconds?
Posted By: Dsteinmann
Date Posted: September 22, 2008 at 10:04 AM
It Does not do this when unarmed and remote started. Or if i arm it then remote start it then unarm it quites trying to unlock? Any Ideas

So i guess i narrowed it down a bit I unplugged the Door Lock Harness (green & Blue) and also the H2 Harness Off the Viper In one of its locking fits. And it was still doing it. So I guess it may be the 1701G (the Settings are still default). I didnt see anything else on the Viper that could be sending out lock commands with the 2 harness removed. So is it a setting on the Truck or the 1701g or could this be a flakey 1701g. I did notice it doesnt always do it now though.
