viper 5901 2007 gmc sierra classic

Have it figured out where I will put the brain.

got everything hooked up, and the xk01 light stayed solid. stayed solid no matter what. so i decided to pick up an idatalink ads-dl that has been flashed with the correct firmware for my truck. it doesnt have the correct d2d wire, so i will go wire to wire. have a few questions. the ground when armed is -500ma the 3 pin door lock outputs are -500ma the oem alarm disarm output is -200ma do i use relays when hooking these up, or just solder them to the correct wires on the bypass? tach output(ac) output on bypass to input on the h2/9? or is there something else i have to connect? thanks in advance, i appreciate it. Matt

roger on no relays. tach input to tach output? or connect them together, and connect them to the wire on the back of the cluster? Thanks, tedmond! matt

Tach output of bypass module to tach input of viper

yes that is correct.

you have 2 options.

1) connect idatalink tach output to viper tach input

2) run it on voltage sense.

I would go method 2, since the tach source is even reliable from canbus units, they have a slight delay. if you do option 2, it wont grind anyways because the truck has an antigrind circuit built in.

Does this delay ever cause any issues?  If so, what would you notice?

well on cars that do not have an antigrind circuit built in, the starter will grind for a few miliseconds, but on this truck you do not have to worry.Ted

due to not having a garage, i had to wait to work on my truck. the weather was nice enough to put this thing in. soldered everything up. programmed from manual to auto trans, programmed the tach, programmed the bypass. have it wired from the 5901 to the tach wire behind the dash. press the remote start button, the truck turns over 3 times, but doesnt stay running. ideas?

armed the truck turns over 3 times, and that is it. UNarmed, unlocked, press the remote start and it fires right over. :/
