Hello!

I just bought a used Tahoe, I plan on installing a remote starter in the next week or two. Can someone point me in the right direction for the color codes for this vehicle?

Also, its been a few yrs since I installed one, my last one was a CS RS900VII that I liked a lot mostly due to its range. However, Ive been running a few searches here and havent seen anyone really recommend them so if you dont mind sharing whats the lastest best bang for your dollar these days???

Im even considering an add-on that lets me use the oem remotes since the range isnt too bad for a factory remote. Are add-on type RS's any easier to install?

TIA!

Add on's are easy, they use the motor wires from the locks to activate. On your truck all three wires needed are in the fuse box amking it real easy. You'll need a bypass for the Passlock2. Get the tach from the back of the cluster, white wire., much easier than going to the ECM...

Mike: A big thnx for getting this info to me faaassttt!

I have a question about the Paslock, Im unfamiliar with this unit......is there a chip in my ignition key (black handle)like my Ford Taurus has?

I ask only cuz my spare key is all metal, meaning no black plastic on the handle and it runs without any issues, is it possible its been disabled already?

Ive learned the car had an alarm system at some time in its life so I suppose its possible.

Your truck has GM's PasslockII system. They moved the 'chip' from the key into the ignition cylinder, allowing you to get a $2.00 key cut and still preventing hot-wiring of the vehicle. If the vehicle had an alarm only, then the passlock would not have been bypassed as bypassing the passlock is only necessary for remote starting.
You will need to bypass the passlock system for remote starting. I recommend a bypass like the one listed in the wiring chart. The one in the chart is the 556L from DEI, this unit relearns the required resistance code every time the key is used to start the vehicle.   The downside to the 556L is that you must cut the factory wire in the truck. Bypasskit.com offers a unit that will provide the correct information to the vehicle without requiring you to cut any of the factory wiring. Here is a link to their device.
Hope this helps.

Im installing a UltraStart 1250, am I going to need to hook up a 451M?

Im asking only cuz I found it along with the 555L under my dash. Apparantly, the dope I bought the car from snatched his alarm system but left these other two units in place.

(I call him a dope only cuz between the bare wires and the lack of reattaching 2 other wires that needed attaching after ripping the alarm system out caused my starter to fry a few weeks ago. Remote Start, 2001 Chevy Tahoe -- posted image.)

yes you should leave the 451m in there. The ultrastart does not have enough amperage to lock/unlock does on its own.

Actually the ultra start only had negative outputs for door locks and the tahoe has positive trigger door locks ie requiring the 451 to convert polarity....

Thnx guys!

Im actually in the middle of the install as I type this and ran into some more unknown territory.

On the DEI 555L unit, the directions give an explanation of where each wire goes (6 of 8) except for two (blk/wh and violet) that aren't needed for my application.

However, in the wiring diagram they only show three hooked up:

blk/yell = r code output to BCM------yell = r code ignition switch side------black = ground reference wire

Does anyone know off the top of their head if the other three wires need to be connected?

TIA!
