TPI in Jeep, can't read codes with Snap-on MT2500

Hi, my name is Caspar, I live in Norway and have a Jeep with a GM 307 with TPI from (I belive) a 91 Camaro. I have some problems with the idling, but The MT2500 wont conect to the ECU. Can anyone help me with som tips about what can be the problem?
The ECU have this number 01227730
The wiring loom is from PW,
I have tested the scanner on a my87 GM Astro, and it connected perfect

How many wires are on the back side of the aldl connector? Some older aftermarket harnesses are missing 1 wire to make them work correctly with TPI
