DesignTech remote starter problems

I am currently installing an AutoCommand Add-On remote starter and the instructions say to connect the RED / WHITE wire to the output wire of my remote car alarm or keyless entry system. I'm installing it on a 2003 Chevrolet Tahoe and I dont know where my keyless entry system is located and which wire is the output wire. Does anybody know this information??? Thank you so much.

Or maybe even an idea of where I could find this information?

I believe on those units you can program the system to trigger after receiveing two consecutive negative pulses. In this case you would use your unlock wire to trigger a relay (to give you a negative pulse)
85 door lock
86 ground
87 ground
30 RED / white

Also, you can connect the trigger wire directly to the lock motor wire (set it for double pulse activation). It will rest at ground and go to +12 volts when lock is activated. When the wire goes back to ground, the remote start will consider that a pulse. This will eliminate the need of a relay for you. The best place to grab the lock wire will either be in the driver's door or under the back seat. A BCM is under the rear seat and has doorlock relays for the 2 back doors. The wire should be grey.

Thank you but does anyone know an easier method? If I could just find out where the PassLockII brain is located then I could very easily just connect this wire to the remote control output. Thank you for your help

there is no easier method. Your factory Keyless entry doesn't have any Auxalary outputs to trigger the remote start. So follow the instuctions that Kickyride said,

Is up to the installer to test all wires with a DMM whenever possible.

I dont need to use an auxalary output, I need to find the wire that controls the remote control so It can be connected to that. There must be an easier way, thank you

design tech remote starts are a waste of money i am sure you like your car and aparently since you want to add a remote start to it . they are some of the worst on the market . why waist your time and others. audiovox,dei and others are the best bet .

Well thanks for input that was completely unnecessary considering it doesn't answer my question or have a reason. Another thing, I don't think I'm going to listen to somebody who lacks spelling skills and common knowledge grammar skills. Not to mention the fact that you sound as if you roam forums trying to make yourself important enough for someone else to listen to with your "know it all" skill. There are better ways of going about giving your opinion so that you don't sound like a complete idiot. I would suggest reading what you type before you post it and to think about how stupid it will make you look. Thank you for your time. Is there anybody out there that would like to help me out? Thank you

P.S. - No thanks to the ridiculous, waste of time comments such as the one above

I for one will not help you. I cant spell myself. Hope no one else gives you any tips either. you have the best minds in the biz on this board we see this stuff every day. I suck at grammer too.

Thats like throwing a Begger a Quarter and he hits you cause he wanted a dollar. BOY I think you just SH;T in your own nest. Who taught you your manners? A snake?

Dude, csorb gave you the correct answer; it would take just a few minutes' time with one relay to use the car's "lock motor" wire to activate the remote starter.

Then kickyride comes along with advice to simply tie the activation input directly into the car's lock motor wire, and that the relay wouldn't even be necessary. I didn't think this would work properly myself, but if it's worked for him in the past, I'm anxious to try it someday.

Your factory keyless entry system isn't an individual piece; it's likely part of the car's BCM (Body Computer Module), although I can't say for sure. At any rate, even if you did find it, most of the pieces in that car communicate via a serial dataline; not an ordinary 12-volt system.

Furthermore, what extra outputs would you expect to find? There are no unused buttons on your factory remote. The best you can do is what's mentioned above--configure the remote starter so that if the car is locked three times in a row, the engine starts. That is, if it's even possible to program the remote starter to require multiple pulses before starting. And since the lock motor wire is easily found at many places in the car, there's little need to find the keyless entry system itself.

At the driver's side fuse box is a square black plug, with several gray and tan wires. One of the grays is lock motor; it turns positive when you lock the doors. One of the tans is passenger's unlock motor; it turns positive when you press "unlock" on the remote twice. The driver's unlock motor can only be had in the driver's door.

Where I work, I end up doing a couple of these add-on remote starts here and there, if a customer requests it. And about half of those customers come back a week later and replace it with a unit that has its own remotes. Factory remotes have very limited range, and most people are dissatisfied with these systems.

If you can afford a $40-something,000 vehicle that gets 13MPG in the city, you might as well do it the right way.

Get a good brand-name (not DesignTech) remote starter that also has keyless entry and trunk outputs, get a good self-learning Passlock bypass module, and a databus interface so that you can operate the Tahoe's lock, unlock, and panic features from your new remote---this is better than having to carry two remotes all the time.

I just did remote start in a 2003 Yukon XL yesterday morning. I used Audiovox products: PRO-9555 remote start, AS-GM4 Passlock interface, and AVXGMDL4 databus interface. You can also find Passlock and databus interfaces at www.transponderbypass.com.

It wasn't cheap; we charge the GMC dealer $350 installed. But now the customer will have only to carry one long-range remote that will operate everything. They will be happy.

Thank you very much Chris, I'm not an avid installer and so I don't understand what you profesionals say but you have clearly explained it now without being rude. Thank you for your input and suggestions, I might just have to interchange it.

Come on guys & gals !!! Try to keep the forums clean & free of needless brand bashing. Everyone is entitled to their opinions ( when the posts asks for it ) and it's only an opinion. We need to set a better example for other people who come by these pages for help, but instead they see some whiners complaining about a brand of remote starter. If we're here as PROFESSIONALS on these forums to help other's, then I think we should act like professionals and keep our consumer biases to ourselves until asked for.  That's my 2 c's and if you have something to say about this please post to me personally & professionally.

Smithwesson625, you're welcome. Sometimes the instructions for these products aren't clear, and we should all avoid letting it turn into an argument.

When DesignTech says to tie that wire into the output of a keyless entry, they're talking about an

Mainly, the deciding factor is if the range of the factory keyless entry is sufficient for you. Even it it works from your house, it may not work from your workplace.aftermarket keyless entry, which usually does have an extra output.

Anyway, the deciding factor is: does your factory keyless entry have sufficient range? Even if it operates from inside your house, it may not operate from your workplace or friends houses---it never hurts to test it though.
