2001 Chevrolet Suburban Alarm/Remote Start

Anyone ever done a remote start install in a 2001 or similar Chevrolet Suburban? Anything special that needs to be done? Where can I find the complete wiring locations - the ones I have found online are fairly vague with quite a few instances of the same color wire...

Help is much appreciated!

Thanks

Here ya go Dan.

Dan,

I just did an '02 last week.  It was actually a pretty easy install.  A couple of tips for you...you can get to the lock/unlock, parking lights, and alarm disarm at the bcm which is right under the steering column.  This will keep you from having to dig for them in the driver's kick panel and at the headlight switch.  The lock/unlock are in the brown plug, the parking lights are in the light blue plug, and the disarm wire is in the purple plug.  Wiring colors are all the same as mentioned in the diagram above.  Make sure that you get the white ignition 2 wire hooked up.  If you don't, major transmission problems will follow.  Also, the best place I found to put the hood switch is on the brace on the driver's side that goes from the firewall over to the fender.  Good luck, let me know if you have any questions! 

IrishDoc,

This shouldn't be a 5 wire lock system, it should be a straight positive trip.  They aren't like the old Suburbans and pickups.  I have done 4 or 5 of these and they have all been a straight positive pulse to trip the locks.  Has anyone else seen one of these that is a reverse polarity?

Boomer and viking, thanks for the great posts. What do you mean about the White IGN 2 wire - do I just tie that in with the other ignition wire? You have me really nervous now that I'm going to screw up the transmission - how woudl that happen? Also, where is the BCM, and are the wire colors in there the same as in the diagram above? And one last question - what is PASSLOCK II - is that kind of like BMW's EWS (something I'm familiar with) that needs a transponder or something? Is it certain that I have this - only reason I ask is because I had extra plain metal duplicate keys made and they start the vehicle no problem - making me think there is no transponder system installed. Thanks for the help, hopefully I can do this!

The remote starter unit will have a 2nd IGN output (-) or (+) depending on the system that you have. Most will be (-) that will trigger a relay to engage the 2nd IGN to power on during remote start. Use this diagram to trigger the 2md IGN with a (-) output from the alarm: http://www.velocitymotorsport.com/images/install_notes/N2P.jpg

If you do not have a designated (-) or (+) trigger output for the 2nd IGN wire, use this diagram : http://www.velocitymotorsport.com/images/install_notes/2nd_ignition_relay.jpg

If the 2nd IGN doesn't receive power during remote start, this circuit doesn't get activated when you take over with the key in the ignition, therefore the transmossion computer doesn't engage and you get harsh shifting almost right away. If this persists and you do not do anything about it, the transmission will get damged.

The BCM is located behind the drivers side of the dash. The plugs on the BCM face towards the rear of the vehicle. You will be able to find all the wires there as listed above.

Passlock II system explained

The Passlock II system is not in the key anymore, it's in the ignition column.

Wow, thanks for the GREAT info. I'll go ahead and get a PLXR. One other question - I should be using relays for all the starter wires I assume - do they usually come with the remote starter or do I get them seperately?

Thanks,

Dan
