Installing a remote starter. Have downloaded two different wiring diagrams that mention the YEL, PNK, ORG, WHT wires. No mention of the large brown wire that's in the same bundle. Anyone know what this wire is for and if it's needed? Thanks.

this is a second accessory wire and is sometimes needed and sometimes not what we do is once we have installed the remote starter we check two things, one we check that the heat and blower come on during remote start ad the air conditioning, second we always check to make sure the alternator is charging during remote start, if any of these things are not working then you have to find another accs. wire and energize it.

Thanks. Install went well - a bit tedious. I did take extra time to solder ignition and power leads. Now, the easiest thing has me stumped! The horn wire is supposed to be black coming from the steering column. Well, there are three black wires coming from the steering column and not one is an open circuit that grounds when you press the horn on the steering wheel.. Any ideas on this one?

Also, the factory alarm is not arming with lock. I think I can get it to do this if I take the negative output of the lock wire from the remote starter before it gets to the polarity inverter (SIlverado locks are positive) and tap this into the driver's doorpin wire. Wiring diagram shows grounding this at the same time as locking to arm factory alarm. What do you think?

Thanks for everyone's input - hopefully I can contribute Silverado and Trailblazer tips soon (Trailblazer is next).

Wanted to take the trunk pop circuit from the remote starter and use it to activate the rear defogger, but the switch for this is in an hvac module and it appears that pressing the button activates a timer circuit INSIDE the module that then activates a relay downstream somewhere. Rats - I really wanted to do this. Looks like the Trailblazer is the same way. Any GM HVAC gurus out there?

Update: a little more time and I've identified the horn wires and that's working. Also found the doorpin wire on the SIlverado and the rearm is working.
