88s 2.5L4 tbi isa does not work

[500kalle]

The isa of my 88s 2.5L4 tbi MJ does not work, I changed into a new one but there's still the same issue, it does not move in or out!

Does someone know where the isa's wires are connected and how I may check if there's the right connection/contact/signal on each wire?

E.g.: which wire is connected to ground, which to the ecu on which clamb, ..... aso!!!

Thanks a lot from germany!!!!
