trouble wiring my xk01 and 5901 together

What is the vehicle? Make - model - year?

If it is GM then I can help.

I have installed many xko1's so I know what you need for wire connections.

Sorry, I don't know wire designations for viper 5901 but maybe the following will help.

Ground while running is an output wire from your remote starter( r/s)

Any wire coming out of your r/s that is labeled "ground while running" is what you connect to brown wire of xko1.

If there is no wire actually designated as "ground while running" then you will probably have to program a wire for that purpose.  Or you can test wires to find one.

Most, lock modules require a neg(-) feed from r/s for lock wires. So if you have both pos(+) and neg feeds, use neg.

So connect xko1 blue-unlock to r/s blue neg unlock, connect xko1 green lock to r/s neg lock.

The violet wire from xko1 is the data bus wire for GM. Purple wire at computer plug.

Red to 12v constant, black to ground

The orange wire is for trunk if you have one.

Oh, forgot to mention, the "ground while running" may be labeled "active while running"

If you find a smaller, ga.(20-22 ga.) wire indicated "active" or "ground" while running is is probably a "neg" feed for a bypass or lock module.

Most pos feeds from r/s modules are larger wires.

What kind of vehicle is this going in to?

The brown wire should go to the relay out harness on the 5901.  The blue wire is "Blue RS Status (-) 200mA"

Blue/Green on the xk01 should run to the blue/green on the door lock harness for the 5901.

Violet/White you shouldn't need to use.

Orange usually needs to be connected if the factory security doesn't disarm upon remote starting. 

v7guy,

I have done hundreds of this car.

Wire it like  I described above, tape off any remaining wires. To be honest, I haven't had much luck with the XKO1 in the trailblazer. I switched to the GMDLBP, and have had no problems with it.

The main complaint with the XKO1's was start but locks wouldn't work. I reset a lot of XKO1's and some never came back but many did.

My installs were mainly in the Envoys which seem to be a little pickier than the trailblazers but I thought I better tell you about my experience with the XKO1's.

If you have leather factory heated seats then you may want to consider the DLPKGM. It is supposed to turn the seat heat on if the engine temp is less than 30 degrees.

Both these modules are easily programmed maually.

Unless you are a shop installer, avoid the idatalink components. I use them and I like them, but you can't programm them manually.

Good luck, let us know if you need more help.

i have used dozens of XK01's on Envoys, Trailblazer, etc with the 5901 and 5501 in D2D with no issues or comebacks at all..... in fact these and the 03-07 CK's are the only vehicles i actually use D2D on at all anymore......

like i said.... one wire to connect.... that's it......
