2008 jeep patriot

I have installed a Prestige APS-901 in a 2008 Jeep Patriot. I did it the old-fashioned way & didn't use a bypass module. Everything works fine, except that I get a horn chirp when remotely starting, after factory alarm is set.

I tried a ground pulse to keysense wire (second starter wire) (PURPLE / brown) with an 8.5K ohm resistor, but that didn't work.

Looking for ideas/solutions,

Thanks 

One possible way is to open the horn relay output while GWR is active.

That's a good idea. I could do that if there's no other solution.

Thanks

You probably dont want to.. but a PKUMUX from DEI will take car of all the MUX requirements AND that keysense/HONK issue.   Only drawback with interrupting the horn is you'd lose your panic while running on RS.

Are you sure the PKUMUX will stop the horn honk issue ? Reason i ask is i have a 2010 dodge ram with a 5901 & chall bypass that does the same thing .

I get a horn honk on disarm & remote starting & was told the only way it can be turned off is via the dealership & the starscan tool .

Thanks for all the suggestions. I think maybe I didn't have the resistance just right for "keysense".

Next time I will use a PKUMUX.
