1997 Grand Cherokee, remote start

What wires do you have Powered under Remote Start?

Did you program TACH correctly?

I received the confirmation tone from the remote and the flashing lights when I did the TACH programming, so it should be programmed correctly.  I do have the starter interrupt relay installed.  And you know what, I redid the wiring on it the other day because they show it connected two different ways in the installation manual, and I wonder if I need to wire it back the way it was.  The one diagram has pin 86 tied into the IGN 1 wire in the ignition harness, while the other diagram has the IGN 1 wire from the brain connected to pin 86 of the relay, with nothing connected to the IGN wire in the harness.  That could very well be my problem.  Let me go and but it back the way I had it the first time (with pin 86 connected to the IGN 1 wire in the harness), and see if that makes it work.

I got mine working. It was the Tach wire. The voltage sense option simply doesn't work on the Air Wolf. A couple of other items the next installer should be aware of. The First is inconsistant wiring instructions in the manual, the diagrams involved are the dome supervision and the door trigger. In the Dome light diagram is correct. The same diagram under the door trigger section has the wrong polarity wire for the door trigger. Secondly, make sure you use the hood switch, it is very difficult to change the program dip switch after everything is tucked away, the hood switch accomplishes the same programming function. Third, don't use the voltage sense wire. Design Tech has an application note that this is an easier and reliable method. Don't do it, it doesn't work and will take you into hours of diagnostic testing and frustration. Lastly, make sure you use a data module with your install. It is a world of difference with install time and wiring compexity. I bought a DEI 455J on Ebay for $31.00.
