I'm looking for an wiring diagram for an 2005 Chevy classic. The only diagram i can find are for the Chevy malibu. I'm not looking to remote start, but only car security. Any relays needed with this vehicle?

I have an 2005 chevrolet classic. I looked up the wiring diagram and I am trying to locate the horn wire, which the wiring diagram states it is a black (-) wire located in the steering column. I disassembled the cover from the column and looked under the dash but can't find the location of my horn wire. The parking lights wire is said to be a brown(+) wire in the passenger kick panel. There are 6 brown wires in the passenger kick panel. Could someone guide me in the direction to finding the horn and parking lights wires?

What kind of relay do I need for the lock/unlock since they both use the same negative wire?

If you are not doing a viper you can still use the 451m and hook it up like-
small plug with green blue red-cut off harness and connect green to lock output of alarm blue to unlock output of alarm red to constant
larger wires blue/black with 1500 ohm resistor to cars lock/unlock wire
larger wires green/black to same wire with no resistor added
purple and purple black to ground and white/black brown/black not used

The 451m relay was not needed.
