Valet 562t with bypass in 2008 Silverado

[ccates21 10+ year member]

I'm looking for a little guidance. I've installed one Ungo alarm/keyless entry about 10 years ago when I got MECP Certified for fun (I'm an nerd)... And now my buddy wants to put a keyless/remote start on his work truck. I ordered him the Valet 562t and the PKUGM2X bypass for his Passlock PK3+ and actuators/relays. Now I have the challenge of installing it once they get here. I have the manuals already, but a few things look odd. (maybe since I've never done remote start before!) The locks arent hard, but a few bumps in the road that I'm having are:

- Getting a wiring diagram for the 2007(new body) or 2008 Silverado (4.8L)

- Which two wires go from the 562t to the "start" and "ground while running" inputs of the PKUGM2X?

- Where do the rest of the r/s wires from the 562t go?-- since the PKUGM2X is connected to all the ignition, keyside, starter side, etc.

- And does the 562t need add'l relays for the r/s harness? The diagram looks like they're included, but I don't want to assume)

- Maybe a few more q's later about the 562t harnesses, but these will do for now. I'll know better when I see it.

I'm sure with a little probing and trial/error, I can hold my own here. But a little help would really be appreciated so I don't fry the brain.

Thanks guys.

everything in that year silvarado is right under the steering colum at the BCM... these trucks are very easy to install rem.start's on...

install the remote start/ keyless/ and door actuators first and get it all working properly ( locks, get the truck to crank but it wont start due to the bypass not installed yet, program tach ect...) then once you get to that point install the bypass... from the bypass the start input will go to the start off of the rem.start unit. and the ground while running input hooks up to ground while running output on the rem. start or the blue (- status output) this wire tells the bypass to turn on or off...

let me know if you need more help.. i install about 2-3 remote start's daily..

The first one is always the hardest they get easier after that.....

Thanks Seth... Hopefully things will go smoothly. Any insight on where to get the Silverado wiring diagram? The install is slated for the 18th. I'll keep in touch. You mind giving me your email?

Thanks again.

Okay... So I got the brains in today and things are making a LOT more sense. I have a couple of quick questions, though. All of them about the heavy guage relay satellite wiring harness wires.

On the "heavy gauge relay satellite wiring", after bringing in the the +12v inputs, I have the outputs as follows:

- The "start output to starter (starter side)" will go to the "start" input of the bypass.

- The "output to accessory circuit" will go to the yellow wire in the ignition harness (Provided the under-dash infosheet I've found is correct. This should turn on my climate controls if I'm not mistaken.)

That info should be right. My QUESTIONS are:

- I shouldn't have any use for the "second ignition/acc circuit output" or the optional +12v high current input that is factory-jumpered within the plug... Correct?

- What do I do with the "start input from ignition (key side)" wire and the "output to ignition circuit" since the bypass already sends wires to these?

Other than that, I think that everything else is just about covered... Until we have to program the bypass and brain/transmitters!!!

Thanks again, I appreciate all the help.

Well, that shows how much I payed attention to the bypass diagram!!! Its an INPUT from ignition... And so, I will just tie the pink/white PIN 6 inbetween the key and the bypass on the line to the BCM.

However, I am still a little confused by something that was replied to me on another forum...

The guy said: "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."

The 1300 ohm wire he was talking about-- Is there a diagram anyone could post or send me with this information? I haven't heard ANYHTING about this.

Thanks again,

Chad

Nevermind. He was thinking about the 1701g bypass that doesn't tie into the pink/black wire like the PKUGM2X. All questions are answered, except I'm 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 guess my question is-- Even though the bypass will know when the key is inserted, how will the 562t? The bypass doesn't output that signal back to the 562t.

Using my noodle and a little common logic...

When the key is turned and the brake pedal is pressed (to put the car in gear), I'm guessing that the signal from the brake still kills the remote starting process, including power from the 562t to the bypass. And in turn, cuts the transponder data sent to the BCM. But since the transponder key is in the ignition-- the circuit is still made, transponder data is still present, and the car continues to run.

I think I'm getting it...

Any replies with some answers, reassurance, or just "you're an idiot if you do it that way" would be great.

Thanks.
