xk531 programming issues

Anybody on here ever have issues getting these to work 100%? I did a 791xv (Viper) on a 00 Grand Cherokee today, and it took forever for me to get it to program. I even opened it up and put the board next to the tumbler. I got it to start and stay running, but every now and then it stutters like I got no tach, then it starts on the second try. Any ideas?

Tried that initially, but moved it to the coil wires (tan/orange) after no successful starts on the injector wires.

May I ask where exactly the Coil wires are run? Do they as well as the injector wires run inside the jeep or both located in the engine?

Where the hell do you think the coil wires are? Up the yazzoo? Guess where if they go to the plugs?

Oh they're up the Yazzoo? I didnt look there.  Dang. J/p man. It says its at the ignition Coil and I didnt see any wires there when I first looked.....but its been rainy here the past couple days and havnt really checked it out so I figured I'd ask. Thanks.

I caught mine at the passenger side by the valve cover towards the firewall. There are several Tan/ wires there in that bundle of wires in loom bout 1.5 inches thick. As far as up the yazoo goes, mine is exit only so generally speaking only one thing up in mine, how bout you howie II?
