Horn honk

Use a seperate relay off your door lock output from the remote start unit and wire it to the horn. If needed you can use a diode so that locking the doors with the OEM switch will not cause the horn to honk.

The problem is the door lock pulse is to long ,you get a honk instead of a chirp Lloyd

what kind of keyless entry is this?Houston,TX

"The two most common elements in the universe are H+ and stupidity" (Ellison).

Trigger this with the door lock pulse.I use the same thing (with a 470uf cap for ~0.25s) to reduce a 1 second output pulse for trunk release.

Useing an Amenity Pro-Start Model 2300 Rs Also in looking at the relay print for changing constant to momentary in laymans terms i take a 10K resistor along side of a 1K capacitor from ground to pin 85. Then output from lock relay goes to pin 86 . now needing a neg. output can i put ground on pin 87 & get a momentary neg. output on pin 30 or do i need another relay to switch pos. to neg???

Ok i installed the system above & it works, the beep is just slightly longer than normal , Tryed different capacitors & resistors but am flying blind when it comes to capacitors is there any place to find what they do & what size or value does what? this is interesting Thanks Lloyd

Leave the resistor value alone. You can decrease the pulse by using a smaller cap. Try a 470uf like Toru uses for about 1/4 sec pulse. If too short go a little larger on the cap.
