A18 Connection cause Jeep to stall

0 votes
2011 Jeep Liberty. All works well without the A18 Green/Red wire connected to the Purple wire. The instructions say to not connect these on a Jeep Wrangler. I have a Jeep Liberty.

Jeep will Remote Start fine and then stall in a few seconds.

What is A18 used for and should I just leave it disconnected?

Thank you,

Not sure what a MUX is.


Do I need it? My car stalls  a few seconds later when connected.

Seems to work fine without it.
