KE-30 keyless in a 2003 Chevy Silverado

I am installing the Commando KE-30 keyless entry in my 2003 chevy silverado, it is in and working but what wires on the truck do i use for the Parking lights output from the KE-30 and what wires on the truck do i use for the Horn output? the park light output on the KE-30 is white with 10 AMP fuse inline the horn output is brown with (-) 200 mA

Parking Lights+ brown   +   driver kick panel Parking Lights- gray/black   -   BCM, brown plug, pin B2 Notes: The BCM (Body Control Module) is under the driver side dash. It has 6 plugs in it, the purple plug is on the back. Horn Trigger BLACK / YELLOW to black   -   steering column

The KE-30 is shown as having a on board parking light relay. If the output from the system is positive than you would hook the output from the system to the brown wire in the truck as listed above. If the output is negative then you would hook it to the gray/black listed above. If the parking light circuit has both a supply and output (which is what I think your system is), then I would recommend hooking the parking light supply side to ground and the output side to the gray/black negative parking light trigger at the BCM. By using the negative trigger it will reduce the current being drawn by the aftermarket keyless unit. Hope this helps.
