This plea is going out to anyone with the ACM installed in their s-type, x-type, or XJ.

The audio connectivity module kit comes with a intermediate connector wiring harness at the rear of the head unit that gives power and 'wake-up' signals to the ACM via an offspring pigtail. See the below pic.



Now, here's where I need your help. I'm lacking the harness. I am asking somebody to physically identify the wires on that harness that this little pigtail connector shares, or to the pins on the head unit that correspond, and to which order those apply to the 4-pin connector.




Pics would be FANTASTIC, and you'd have my utmost appreciation and in your debt. Thanks guys!

 

I may be pulling my acm soon. Will be happy to share pics and info following the removal.

Should be a week or so.

Thanks

Mag, et al - I'd be interested in this info as well.

 

Pulled the acm today.

Please see some photos of the harness. Looks like red black and purple on the head unit harness to the ACM box.

Thanks-
Mag

Red is 12V battery permanent power; Black is ground. The purple is the D2B "Wake Up" signal.

 

mag,

Thank you so much for the info.
Can you also send the ACM end of the connector?

I ordered the same molex connector (hopefully) but I don't know which pin goes to where on the ACM connector.

Matt,
thank you so much for the help on getting the information.
