Just added Sirius Satelite radio to my 2004 Z71. It was an easy job until I started looking for a 12v power wire that is only hot when the ignition is on. I hooked up to the orange wire that powers the radio, but that wire is always hot. Does anyone know where I can find a 12v source that is hot only when the ignition is on? I have used the search function, but have not found anything that helps. Thanks in advance for your help.

Do you have an aftermarket radio? The wire you found was constant power for radio memory. You should be able to find a wire coming from the ignition that has power when you turn the key. Get a wiring schematic or just go through them. I have tapped off of the ignition wire to the radio a few times in the past for certain accessories like a radar detector.

The radio is the stock unit. I don't have access to a schematic. I was hoping someone had done this before and would know which wire to tap into. I suppose I will have to pull out the tester and start searching.

You're not going to find a wire at the back of the radio thats switched. The radio uses signals instead of a wire that goes high(12V) or low (0V). Try tapping into a fuse, i think the 800s still had some switched circuits.

i'd tap into the radio fuse on the left side of the dash.. it should work fine that way, radio turns on, sirius turns on with it

I used to use a part from one of those interfacing companies that would wire into the DLC connector and basically become an electronic digital relay if you will, it would read the data codes and provide a RAP ignition lead for adding after market gear. I used to use them for the Satellite radio installs, sometimes for RSE installs, and lots of times for iPod installs before I started using the actual iPod interfaces. I will do some looking again to see if I can find the part number and company name for you if your interested, it has been about 2 years since I did it everyday.

you can go right to the ignition wire in the lower dash under the steering wheel. GM typically uses the same colors for all of these wires. The 12v ignition wire is pink.

When I had my 2007 Classic I used one of those Add-a-circuit fuses and tapped into an unused fuse location for an accessory that I did not have. It was painless and worked quite well.

Goto to Pep Boys and get an "Add-a-Circuit" for a mini fuze. On the very left side of you dash is a fuze panel. Open the driver's side door and you will see it. Pop of the cover. I found only one fuze that toggle with the ignition switch (it was one that only had a 2 amp fuze). Add the "Add-a-Circuit" and you will have a 12V source that switches on and off with the ignition switch.

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ).    I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.
