2004 Explorer remote start relay problem

No, everything was wired correctly.

I installed two relays in order to flash the headlights and honk the horn. When armed, the headlights flash with the parking lights, and during an alarm the horn sounds at the same intervals as the lights but only when the system is armed and the siren has voltage.  I used a special low voltage RBSTTL relay to make a closure from the lower voltage on the brown siren wire when the siren is sounding.

In order to do this I needed to use the orange wire from the main harness to activate a dual relay.  Using the positive power from the parking light circuit I was able to set it up so one side of the relay sends power to the headlight circuit at the same time the parking lights flash providing the system is armed, and the other side sends a ground to the explorers horn circuit providing the TTL relay is also closed from the siren output.   It was the dual relay that was back-feeding a ground into the orange wire and causing the main module to activate the starter kill which is located in the seperate relay pack.  I guess the orange main harness wire is common with a negative trigger for the relay pack's starter kill relay, even though it has a seperate harness.
