2000 silverado alarm/remote start

Hey guys, time for more of your absolutely awesome expertise! I'm about 35% done intalling a alarm/remote start combo in my truck, a 2000 silverado.. Meaning, I installed the alarm part of it, and it seems to work great, except whenever it triggers the park lights, the door chime sounds, just as it would if i turned them on manually.. Any ways around this? I'm sure I used the right wire, they work perfectly, theres just the chime.. Issue #2 Also, in regards to the door locks, my alarm has two different setups that are possible to use, you can choose one of two wires, one is (-) Lock / (+) Unlock and the other is (+) Lock / (-) Unlock. Problem is, on my truck, it uses a postive pulse for both the lock and unlock.. Is it possible to wire both wires up respectively, assuming that the (-) pulse on each wire would be ignored while the (+) pulse might trigger the proper function? Or do I need some kind of relay setup? Issue #3 While trying to wire in the remote start, I had trouble finding the tach wire, the diagram at: https://www.the12volt.com/installbay/detail.asp?info=alarm&year=2000&make=Chevrolet&model=Silverado&ID=17459&type=Alarm says the wire is white, and at the coil, my truck has a V8 and there is a coil for each cylinder, and each coil has a 4 wire plug going into it, I checked all the wires for A/C voltage between 1-6 volts as per the instructions included with my alarm, and non seemed to register any thing in that area, they were either low, (less then 1 volt) or high (10+ volts) I found a wire going into the gauge cluster that is white, and registers voltage only when the engine is running, but its 15+ volts. Is it possible to use this 15+ volt wire? or would it damage my alarm module with the higher voltage? Thanks for all your help guys, sorry for the long post.. :)

Issue #2

Also, in regards to the door locks, my alarm has two different setups that are possible to use, you can choose one of two wires, one is (-) Lock / (+) Unlock and the other is (+) Lock / (-) Unlock. Problem is, on my truck, it uses a postive pulse for both the lock and unlock.. Is it possible to wire both wires up respectively, assuming that the (-) pulse on each wire would be ignored while the (+) pulse might trigger the proper function? Or do I need some kind of relay setup? ** No need to wire up a relay, just hook them up straight to the door lock wires.

While trying to wire in the remote start, I had trouble finding the tach wire, the diagram at:

** It is white at one of the fuel injectors.

Try the negative parking light wire instead of the positive wire.Issue #2What kind of alarm is it? + positive polarity for the doorlocks require for your vechile, so you have to send a positive pulse to it. As daniel2002p said, no relay is required.Issue #3Tach wire is an input wire, you won't damage anything here if you didn't get the correct tach signal. What likely tends to happen when the tach signal is too high is that the starter will under crank.

The door chime will always be there cause the ignition is not energized. It's the system that GM and other manufacturer's use to remond you that the lights are on. No way around this unfortunately. For the tach use the injector not the coil. It's easier to find ( any wire tha tis not PINK ) because there are only 2 wires at each injector one being PINK and the other being a different color, use the other color for your tach signal.Jeff

you cand find the tach by removing the vent in the driver side next to the cluster u will see a gray tape take it off and there are a few wires the tach is the white onehow own your mind, control your life.

Hey guys, back again, well, I got it all worken, some what anyway.. Everything is fully installed, I tried to use a fuel injector wire for the tach wire. Doesn't seem to work for my "Engine Check" function on the remote starter.. The only way the remote starter will actually start the truck is if I set it to crank for a preset amount of time.. (Which means disabling the tach wire function..) Otherwise it cranks for like .2 seconds and stops. I guess I'll try your suggestion dare. Also, in regards to one of my earlier issues, concerning the door chime sounding when the alarm/starter flashes the park lights. I was thinking, there must be some other way other then tying directly into the light switch.. My truck has keyless entry, and when I use the factory remote to unlock/lock the doors, the park lights flash, but the door chime does not sound.. any ideas about this? obviously the keyless module has som sort of alternate setup.. I'm just not sure on where or how to find it. Other then that, everything seems to be working great, and its all thanks to the good advice of the people on this board :)

Oh yeah, one other thing, I didn't do anything with the "factory alarm" other then the obvious Pass-Lock bypass, and everything seems to work, is hooking up the "factory disarm" wire really nessacary? The remote start/alarm doesn't seem to trigger it? The only evidence I've seen of this "factory alarm" is when the power button is pushed to unlock the doors after its been locked with the keyless remote (aka breaking into the truck with a hanger through the door when I've locked my keys inside) At which point the lights flash and the horn honks.. I believe I've tested all the major functions of my alarm/remote starter and nothing seems to trigger the factory alarm?!

I recently installed a Viper 791XV into my 2000 Silverado, and have a small issue regarding the park lights and the door chime. Whenever the alarm arms/disarms and flashes the park lights you can hear the door chime sounding inside the truck.. I noticed the factory keyless entry manages to flash the lights without sounding the door chime.. Right now I'm tied into the park lights at the switch.. I also noticed the wire I tied into is alot heavier gauge then the alarm's. Any ideas?? Is there somewhere else I could tie into the park lights to by-pass the chime?

Try the small brown wire at the BCM above the brake pedal.
