NickRummy Posted April 12, 2011 Report Share Posted April 12, 2011 Hoping to start and finish my Z2 install in my Trailblazer today and I had a few quick question I wanted to ask before starting. I searched and have some good answers for hooking these items up but I'm more curious about understanding exactly what the function is. First, the VSS wire. I found where it's at in my truck (or so I've read). I read that the VSS is not required for use but helps with accuracy right? Now, if I do hook it up it will stop allowing me to enter data if the truck is moving faster than 5mph. Is this true? I'm ok with this as well. The e-brake wire, this is used for the DVD player right? I seen some people modify this with a relay so that DVDs can be played while driving. I have no need for that since my headunit won't play discs right now. Can I just leave this unhooked or is it required for anything else? Reverse signal, is this required for anything as well? I found a place to tap in for it but if I don't have to run the wiring then I won't. haha Thanks! Quote Link to post Share on other sites
