You hook up the 555L according to the instructions it comes with. The van has Passlock II, not Passlock I, so be sure to follow the correct procedure. Passlock R-code wire in the van is yellow, Passlock ground is tan. There are two yellows-----start van, leave it running......cut one of the yellows in half.....if the security light in the dash comes on, you have the correct wire. Also, that van has an anti-overcrank feature, making it impossible to crank the starter too long.........I'd set the remote start for voltage sense, set the cranking time extra-long (like 1.5 seconds), and skip the tach wire.
