First you locate these under the kick panel on the drivers side. Purple and yellow wire. (sorry for the fuzzy pic)
Then you take one of these.
Attach it like this. One end to the purple/yellow wire and the other to the black wire (Ground).
PRESTO Security System Bypassed. This is also the same way for XJ's.
I figured with more and more ZJ's and XJ's going the way of Chuggy, this could be a problem with the super complex wiring of our Heeps. I sure know that once I cut the top off mine and got rid of all the doors and hatch that there just wasn't any way to reset it after I disconnected the battery and reconnected it.
