I want to use the Dealer Option Connector (DOC) that is behind the glove box to power my radar detector and dash cam, rather than tapping off the mirror. Does anyone know the part number for the harness? I realize I could use connectors and go straight onto it, but if there's a reasonably-priced harness I'd rather buy it.

I found this, but I don't consider this "reasonably priced": Holden VF Accessory DOC Plug and Play Harness - Envyous Customs

I figured if it's a DEALER option thing, meant for when these vehicles are used as police cars, there should be a part directly from GM, right? I'd spend $30-40 and be okay with that.

That's about $63.00US, plus shipping from Australia. Rumor has it to be a reworked Commodore VE patch harness, GM/Holden P/N 92188778. I cannot confirm this.

Thanks for that! I'd consider paying $63. Nothing comes up for that part number on gmpartsdirect, any idea how I'd order it? I'm going to try calling the local dealer, too, but this is a good start.

Looks like a nice product listed by @jcoulter36 , at a similar price point to what you are looking at. If you'd rather the GM harness or the Envious Customs piece, check with Holden Parts USA

If you're a DIY'er, the plugs cost about $5 each and come with the pin connectors. They ship directly from China, so it takes a while to receive them. UNFORTUNATELY I cannot find where I purchased mine. Not sure if you've looked at the DOC port, but the wires supplying it are only about a 16 gauge. Plus there's not much space where the DOC is located, so it gets cramped quick.
BTW, just behind the right kick panel is a grounding hub.
Here's a pic of the one I made. Since most devices come with a fused line, I opted not go with a bulky fuse block and instead provided multiple taps.

That's pretty cool! The plug itself, or a factory harness, is what I was looking for. Do you know the part number for the plug, even if you don't know where you ordered it?

The deal mentioned above from the guy on facebook is pretty good. I don't mind paying an individual person in order to not have to make it myself, plus his pictures show nice clean work with a loom and such. I hadn't considered the space requirements of a fuse block, though.

Out of curiosity, what are you connecting?

Think OP said in post #1 he did not want to tap the mirror feed.

Radar detector and dash cam... I haven't personally checked, but I think the fuse that feeds the DOC is a 15 amp. Some of these homemade setups give the appearance you can do so much more. Mine included.

As for the yellow constant hot and the blue vehicle speed wires, they are unused at the moment.

Plus the mirror tap doesn't provide enough current to power some radar detectors. Like My Escort iX.

I really like the idea of using this harness too and have been searching Google for a few days now for the bare connector housing..... with no luck.

I finally figured out where I purchased the blanks, Aliexpress.com. However, I didn't create an account and I didn't keep the email confirmation so I don't have an easy way to find out exactly what part# it is on their website. The info on the plugs that I have don't reference the same plug on the site. It's close but not it.
The orange side is the side that inserts into the DOC. Let me know if you need more pics to assist in your search. Good luck!

Thanks for the info! I'm definitely saving it just in case, but I wound up buying a pre-made cable from Bao Nguyen as mentioned above. He had good reviews and sent pictures and sent tracking info pretty much as soon as I paid. It was definitely more money than doing it myself, but I don't mind paying for quality workmanship that will save me some time, and it was still lower cost and better quality than the ones from Australia! He even made me a custom one with fuse blocks on both constant power and accessory power, for a few extra dollars.

I had no idea the DOC harness was a thing until this post. Since then, I've been slightly obsessed with using it as a clean alternative to the add-a-fuse connector for my dashcam's Cellink NEO battery. It's also one of the few clean ways to get constant 12V under the dash, I believe (although I don't need that at the moment). Anyway, thanks to this thread I found a place stateside that had the plug with a minimum order quantity of 10. I have a package of 14 awg terminal pin connectors on the way... I'll let y'all know how it goes.

Sweet! Consider me in line for one of the other nine harnesses that you assemble. ;)
