2000 silverado, remote start

I am having trouble locating the tach wire on my 2000 Silverado. I have checked the "white" wires that are on the steering column. None of them show 1 to 6 volts AC. I am not sure where to look under the hood. Any help will be greatly appreciated. Thanks in advance - Trent- Trent

Tach will be at the coil.Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

Apparently I am unable to follow instructions...can someone help me understand how to program the Valet 651T? I understand how to get to the different options, but don't understand how to use the inputs to change the values. I only hooked up the negative input, that interfaces with my Viper 300 ESP alarm's Channel 3 negative output. Do I need to also manipulate a positive input to program the Valet?Thanks- Trent- Trent

Talk to me like I'm a two year old. Where is the coil and how do I find the wire there? Thanks for you help.- Trent

Get the tach behind the instrument cluster, white wire. Pop off the bezel and remove the 4 7mm screws, very easy to get to....Mike M2

I'm not familiar with a Valet 651T.Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

I agree with Mike. Easiest place is right behind the cluster, the harness that plugs into the intrument cluster has a white wire which is the tach wire you're looking for. This is where I grab it on every GM full size truck and SUV.

I am beating my head against the wall with this thing. When I used to install, I always thought of these as the easiest vehicles to work on...I have a Valet 561T remote start, with a 555L Passlock Interface. I am still getting the security light flashing at me when it attempts to start the truck. I started it with the key and let it run for about 1 minute, the 555L book said it only needs 15 seconds.I hooked the Yellow wire on the 555L to the Code-Producing Side (Coming from the Key) of the Yellow passlock wire. The Black-Yellow wire on the 55L to the non-Code-producing side (going down the column towards the firewall).The black wire on the 555L is hooked to the ORANGE / black wire coming down the column (the Passlock ground reference).Please tell me what I am doing wrong.- Trent

did you ground the neutral safety switch input?

Yes, but would that cause the factory security system to kick in? One thing I thought might be it, do I need to diode isolate the negative trigger on the 555L? Right now, I have the negative trigger coming out of the Valet Remot Start module going to both the Viper alarm and the 555L. Thanks - Trent- Trent
