The PKU-GM2X's red ignition wire is an input, not an output; you'll need to connect the ignition output from the 562T(the pink pin 6 to the relay pack) up to the car.

Pin 8(2nd ignition/acc.) and pin 7 you are correct - there's no need to connect them to anything.

Pin 2(start input from key) is really not useful on this vehicle. If you were doing a vehicle with a conventional ignition harness you would cut the starter wire in half, and hook the green to the key side and purple to the starter side of that cut wire.  Which brings me to the purple starter wire...

You're right that it will need to go to the bypass - however it may also need to go to the car.  Your wiring info may mention a (+) through 1300 ohm starter wire in the ignition harness.  I've read some sources that say connecting to this wire for remote start is not necessary, when the ignition wire has power and the accessory loses it the truck will crank. Other sources say you have to connect it.  I would say you'd want to connect it to avoid a possible trouble code.

Well, that shows how much I payed attention to the bypass diagram!!!  Input it is.  I'll just tie the pink/white in between the key and the bypass on the line to the BCM.  However, I am a little confused by the 1300 ohm wire you were talking about.  Is there a diagram you could post or send me with this info?  I haven't heard ANYHTING about this.

Thanks again,

You can disregard what I said about the resistance starter wire thru 1300 ohms - it's just the pink/black resistance wire which the PKU-GM2X connects to. 

Rock on.  I was looking at it and thought about that wire, but you just confirmed it.  That about wraps it up!  So I guess I'll just tie off that key-side input on the satellite relay harness and tape it up since the bypass is taking care of that.  I'll get to the install on Presidents Day and hopefully all should be good.  Thanks for all the quick responses.  Its been about 10 years since I've done an alarm, and never a remote start...  So its good to have a hand since its all SLOWLY coming back.

Okay...  So I know that I overthink everything, but I still wanted to bounce this off you because I'm still kinda new to this.  (And I'm an R-tard)

I guess I was a little reluctant to just tie off and tape that key-side pink wire (PIN 6) from the 562t.  Even though the bypass connects to the truck where this PIN 6 would usually connect, I was thinking about what the 562t would see from that circuit.  I guess my question is-- Although the bypass will know when the key is inserted (in order to disable the security features of the remote start), how will the 562t?  The bypass doesn't output that signal back to the 562t.

Using my noodle and a little common logic...

I think I'm getting it now...

Thanks again Chris, you've been a BIG help.

What it sounds like you're doing is confusing "key-side input" with "key sensing".  Also "ignition" with "start".

Ignition circuits need to be active the whole time the car is running.

Key-side input would be used as follows:

The red wires from the XCRS would go to the orange constant 12v, pink would go to pink ign. 12v, pink/white would go to orange acc. 12v, and orange would go to brown acc. 12v+(actually the last two are interchangeable).

That's "key-side starter input".  "Key sense" just lets the truck know that a key is in the ignition.  The 562T doesn't care if a key is in the ignition or not.

Don't mind your confusion - your truck is the source of it here because:

It doesn't have a conventional ignition switch - that pink/black "resistance wire" controls the key sensing, starter, and some ignition circuits that the pink ignition wire doesn't activate.

OK, I'm desperate.

I installed this thing yesterday, and the locks work fine and I can program it all day long. 

The remote start doesn't do squat.  To eliminate the possibility of bad equipment, we replaced the brain, sattelite relay harness, and wiring in between and got the same results.  Even the bypass, but I don't think that its an issue with the bypass, at least not yet.  Read on...

I press the yellow button twice and the 562t's LED doesn't blink, the accessory lights don't come on and the ignition doesn't do anything.  Its like the thing doesn't even get the signal to attempt starting.  After confirming that the yellow button was linked to channel 5 for remote start, I becan troubleshooting.  I put a voltmeter at the purple, pink and orange wires coming from the sattelite relay pack, and they all read ZERO at all times-- even while pushing the yellow button.  Even though the two red wires have constant +12v coming straight from the battery, they never send it toward the bypass or ignition.  I wired the bypass exactly how the instructions said, and tied the accessory into the brown at the ignition.

I thought it could be the brake switch, because the wiring info I got at the BCM was wrong.  I had it wired into purple(and white maybe?) right at the pedal.  So I just cut it instead of having it wired it in at the brake. (No signal is better than some 'little' signal telling it NOT to start, right?)  Nothing.  I have the door lock relays, the brain and the neutral safety switch all grounded at the same place under the dash with a sharp washer and a self-tapping metal screw into a piece of frame.  If it was a grounding issue, nothing would have ground, and nothing should work.  (Notes-- I have left out the "switch" at the NSS wiring. I was told the actual switch wasn't necessary, just ground that wire directly.  Also, I have not connected the tach wire.  I programmed the 562t to voltage-sensing, and then after it didnt work again, to low voltage.  I've also had the tach jumper set to on and off. Don't think the tach matters unless its cranking though.)

WHAT THE HELL AM I DOING WRONG?????   AGGGGHHHHHHH!!!!

Nothing is more frustrating than hooking something up with all of the documentation and having the most important part NOT WORK.  I checked the shutdown diagnostics and it didn't give me an error code.  I guess that means it never shut down, because it never tried to start.

If anyone can help, it would be great.  I'd even throw a couple bucks somebody's way if you're local to the St Louis, MO area and could stop by.  I can email a diagram of exactly what I have everything wired to if that would help.  Feel free to email me too, if you have ANY suggestions.  I'll even take phone calls if its easier.

Thanks,
