What you can use is connector X1 (8 pin)
pin 2 is Right Parking Lamps
pin 3 is Left Parking Lamps
pin 8 is Head Lamps

I would like to suggest you don't use the HORN. The horn is an emergency device, not a casual indicator. It may have never happened to you but it will scare me severly if a horn blows as I walk by a car. I know that new cars do it, but that doesn't make it right. If your system has an emergency horn function, then that is all right, but not just to let you know that the doors lock or unlock.

If you connect pin 2 and 3 together, you will loose the standing light function which we don't need in this country.
