wpageabc Posted November 17, 2006 Report Share Posted November 17, 2006 Connections on stock harness connections to D2. Looking for opinions on wether or not to cut away and solder splice out connections or work around stock connector on Hummer H3. If I leave stock connector it can be swaped back in if sold and remove the D2 for next vehicle? Whats your thoughts... Quote Link to post Share on other sites
tillithz Posted November 17, 2006 Report Share Posted November 17, 2006 of course dont cut the factory harness off. You answered your own question, believe in yourself.. your on the right lines. Quote Link to post Share on other sites
cntrylvr79 Posted November 18, 2006 Report Share Posted November 18, 2006 Not to mention the factory harness does not have a +12 volt accessory wire, so you'll either have to run a tap from the ignition or fuse box. Though the best option would be to obtain a class II databus interface for your truck. Quote Link to post Share on other sites
wpageabc Posted November 23, 2006 Author Report Share Posted November 23, 2006 Good point. There is a +12 Volt lead ignition on or off. Right where its needed. Going to tap it for power... Quote Link to post Share on other sites

Once they sent me the correct one (with the jumper) no mod to the GM side of the connector was needed. Thanks for the tips! Quote Link to post Share on other sites

I also have a Hummer H3 '07 and am going to install my AVIC-Z1 this weekend (from my readings the wiring is same as your AVIC-D2), confused with the harnesses out there for our SUVs. What is the model number of the "Peripherial interface" you had sent that corrected the incorrect GMH24 and where did you obtain it, also what price should I expect to pay? Was your installation relatively simple? I've done stereos, speakers, amps, eq's years ago so feel comfortable but the vehicles 15-20 yrs ago are far different than our H3's of today. Fortunately this forum will make the install a breeze. ...: Louie Alvarez :... Quote Link to post Share on other sites
alvarezlouie Posted September 2, 2007 Report Share Posted September 2, 2007 Using the Metra AAxxess GMOS-04 GM Onstar Digital Interface w/amp for only $40 + $8 shipping from eBay installation of your AVIC into an '06 or '07 Hummer H3 will be a simple process. Anyway turns out this harness has the VSS, reverse, parking brake and mute right on the harness, talk about easy installation. This was a NO-BRAINER! So download the manual to can see all the vehicles this is applicable to and make your AVIC a simply no-brainer, quick, simply slam dunk operation.

wpageabc Posted September 2, 2007 Author Report Share Posted September 2, 2007 That sounds like the way to go. The peripheral interface is not good in my opinion. It works but I would not recommend it... Quote Link to post Share on other sites
installthis06 Posted September 3, 2007 Report Share Posted September 3, 2007 I had a guy come in the other day who decided to cut his 03 s10 harness. Well he came back today and he had to get his ecu replaced and a bcm possibly? $1500 bucks to get repaired because he didn't want to spend 100 on a harness!! Quote Link to post Share on other sites
alvarezlouie Posted September 3, 2007 Report Share Posted September 3, 2007 Although the install went extremely well and easy with the $50 harness the only issue I really had was using the correct double din install kit. The local installation shop I bought mine from sold me the wrong one so the AVIC pushes the H3 panel forward. Anyone know of a kit, where to get that will get the AVIC flush with the panel, so I can get rid of the crap the shop sold me? Quote Link to post Share on other sites
wpageabc Posted September 15, 2007 Author Report Share Posted September 15, 2007 There are other interfaces out there do a google search and check carefully. peripheral works but its expensive and unclean. Quote Link to post Share on other sites
