Make sure the MUX output is NOT connected. This is the GREEN/RED wire from the EVO-ALL 20-pin connetor. It should not be connected on the Wrangler.

Thanks for reply.

I have CHRT5 harness and I have not connected the 20pin cable.

How can I solve?

thanks
The yellow wire in the 20 pin connector needs to be used, please follow the installation guide at fortin.ca

Hello,

yes, from 20pin connector only the yellow cable for ignition is connected.

 

Maybe another solution for this issue?

 

thanks

Only time I see this issue is on vehicles over seas.

We have not tested those vehicles as the computers are not flashed the same as their north american counterpart.
