2002 f150, alarm/remote start

I have a 2002 Ford F150 and I have off band carvox fm 2 way alarm. I installed and the door keep seting it off I used the the BLACK / YELLOW catches the drivers door and the BLACK/ pink at the GEM module located above the fuse box . it works but in 1hr to 2 hrs it gose off on the doors open

You need to diode isolate the pin wires. break the wires at the ECM and put a diode in line with the cathode AWAY from the ECM.

Now past those diodes (remember AWAY from the ECM) is were you will grab your triggers now. You will need 2 more diodes. Split the negative

trigger input from your alarm, put the diodes one to each (blk/yllw, blk/pink) with the cathode AWAY from your alarm brain.

The cathode end is the end with the white line.

Well, hang tight here, someone should come up with a better suggestion for ya.

all diodes facing the correct direction? I know it sounds stupid, but.

now when i get the line befor or after the diode from GEM my email is kd5olt@sbcglobal.net

?? is thare a + door trigger on the ford F150 if so were is it
