Hello all,
I have a remote start from clifford 50.7x, a 2001 gmc yukon xl, and a pljx bypass that I want to install. Now, my issues: I have the remote start, but there was no install guide in the box, and I am having trouble finding one online. Also, I want to make sure that the guides posted here for a 2000-2002 suburban will also work for me. I know they are the same vehicle but I want to make sure that all the wiring is the same. Anyhow so I guess I'm requesting for a diagram of the alarm and a diagram of the truck. If anyone could let me know any issues I might run into, that would be great. Also how to wire the pljx... I got the diagram from xpresskit.com and its pretty vague. Any help would be great!!! Thanks,
Marshall

I didn't realize how small the diagram would look. I will post a better copy.

Thanks for the diagram for the truck. I really appreciate it. What I really needed though was the diagram for the alarm itself. It did not come with one at all.

Never mind I'm an idiot, I found it in the downloads section... Thanks guys let you know if I have any issues!

So, I am having difficulties installing this... I'm not sure what the labels on DEI's stuff means, can you or someone else possibly tell me what I need to connect where??? I found all the wires that were on the direct wire diagram inside of the truck. What I don't understand is what wires from the alarm harness I hook where... I'm assuming I have to make the door locks a positive output???

I'm sorry about the late reply. My next post will go into a little more detail about where to connect most of the wires.

On the thick gauge harness (10 pin harness)
Pin H3/1 - Pink - connects to the Pink ignition wire
Pin H3/2 - RED / White - connects to the Red 12v constant wire
Pin H3/3 - Orange - connects to the orange accessory wire
Pin H3/4 - Violet - connects to the yellow starter wire
Pin H3/5 - Green - not used unless you want the starter anti-grind function (optional)
Pin H3/6 - Red - also connects to the Red 12v constant wire
Pin H3/7 - Pink/White - connects to the white 2nd ignition wire (must connect this wire to prevent possible transmission damage or check engine light from coming on)
Pin H3/8 - Pink/Black - (optional) no connection (just cut and tape it)
Pin H3/9 - RED / Black - also connects to the Red 12v constant wire
Pin H3/10 - No Connection
There is also a 2nd Accessory wire (Brown) that will require a relay to power up.
- Connect Pins 30 and 85 to the Red 12v constant wire of the car
- Connect Pin 87 to the Brown 2nd Accessory wire of the car
- Connect Pin 86 to the orange wire (H2/12) of the 18 pin Viper harness

The power lock wires require a positive trigger. The 3 pin lock harness (which only has 2 wires) only gives a negative output so you will need relays or a door module such as the DEI 451M to convert the negative pulses to positive ones.
Blue - unlock output
Green - Lock output
If not using the 451M, you would wire 2 relays like this
On the Yukon, the power lock wires are in the Brown Plug of the BCM
Lock - Light Blue (pin A4)
Unlock - White (pin A3)

Primay 12 pin harness on the Viper system
H1/1 - RED / White (for trunk) - not used since the trunk unlocks with the rest of the doors
H1/2 - Red - goes to a 12v constant wire (Red from ignition harness)
H1/3 - brown - connects to the red positive wire of the siren
H1/4 - WHITE/ brown - not used (just cut and tape)
H1/5 - black - chassis ground
H1/6 - violet - not used (just cut and tape)
H1/7 - Blue - connects to pink/black for trunk trigger at BCM it's the light blue plug, pin B10
H1/8 - Green - connects to tan door trigger at BCM purple plug
H1/9 - BLACK/ white - connects to gray/black at BCM blue plug
H1/10 - WHITE/ blue - not used
H1/11 - white - connects to negative parking light white wire at BCM blue plug, pin A5 (make sure to set the polarity on the remote start brain to negative trigger for the lights)
H1/12 - orange - not used

The 18 pin harness should be fairly simple but I can post info on that one also if needed. Hope that helps you!

I could use the 18 pin harness as well but i should be able to figure it out. man great work really appreciate your help!!!

Sure, not a problem at all.
H2/1 LIGHT GREEN/ BLACK (-) 200mA OEM ALARM DISARM OUTPUT
connects to light green at BCM, purple plug, pin B3
H2/2 ORANGE / BLACK (-) 200mA AUX 4 OUTPUT
optional - not needed in this setup
H2/3 GREEN / WHITE (-) 200mA OEM ALARM ARM OUTPUT
arms on lock with door open - you would have to split this wire into two ends and place diodes (1 amp 1N400x) with the band facing the GREEN / WHITE wire. Connect one end to the DOOR TRIGGER wire and the other to the LOCK wire.
H2/4 VIOLET/BLACK (-) 200mA AUX 2 OUTPUT
optional - not needed in this setup
H2/5 WHITE/ BLACK (-) 200mA AUX 3 OUTPUT
optional - not needed in this setup
H2/6 WHITE/ VIOLET (-) 200mA AUX 1 OUTPUT
optional - not needed in this setup
H2/7 GREY/BLACK (-) DIESEL WAIT TO START INPUT
not used for this vehicle
H2/8 BROWN / BLACK (-) 200mA HORN HONK OUTPUT
black wire at BCM, brown plug, pin A9
H2/9 VIOLET/WHITE TACHOMETER INPUT
any fuel injector's uncommon wire OR at the ECM, plug labeled "red", pin 10, The ECM (Engine Control Module) is located near the battery, down low, between the fender and the fan under the black plastic cover. Might just be easier to go to an injector.
H2/10 DARK BLUE (-) 200mA STATUS OUTPUT
used to power the Ground when running input of the bypass unit
H2/11 PINK/WHITE (-) 200mA FLEX RELAY CONTROL OUTPUT
optional - not needed in this setup
H2/12 ORANGE (-) 200mA ACCESSORY OUTPUT
optional - not needed in this setup
H2/13 PURPLE (-) 200mA STARTER OUTPUT
optional - not needed in this setup
H2/14 PINK (-) 200mA IGNITION 1 OUTPUT
optional - not needed in this setup
H2/15 GREY (-) HOOD PIN INPUT (N/C OR N/O)
connects to your hood pin that came with the alarm
H2/16 BLUE/WHITE (-) 200mA 2ND STATUS /REAR DEFOGGER OUTPUT
optional - not needed in this setup (can be setup to turn on the rear defroster but i don't know which wire controls it on your vehicle)
H2/17 BROWN (+) BRAKE SHUTDOWN INPUT
white at the brake switch
H2/18 BLACK/ WHITE (-) NEUTRAL SAFETY INPUT
if it's automatic, connect with your ground. if it's manual, connect to the parking brake wire (light blue wire at the parking brake switch)
Hope that helps!! I'm sorry I didn't post it before. Let us know if you need any other info. It's our pleasure to help you.
