I found a youtube video that shows the wires and what each one is on the blue connector. Did a screen shot and labeled the wires.

Keep in mind that the wires are 12v and the dashcam is 5v. I bought these adapters and wired it in with the supplied USB plug from the camera. https://www.amazon.com/dp/B07594WT6K

Everything is tucked back into the headliner and worked out perfect.

PS: what is the blue connector plugs into? or it just an extra plug hanging there ?

That's the plug for the OEM dashcam. It's tucked in with one of the wires up there.

I did not cut the wires out from the blue connector. I tapped the wires about 2 inches away from the blue connector by splitting the insulation on each wire and exposing the copper. I used a tool like this that pulls the insulation apart: https://www.amazon.com/Self-Adjusting-Stripper-Klein-Tools-11061/dp/B00CXKOEQ6

It wouldn't hurt to cut the wires if you need to. If you're against cutting the wires, you can also use a razor blade or utility knife to shave away some of the insulation or use wire taps like these: https://www.amazon.com/Connectors-Solderless-Electrical-Certificated-Stripping/dp/B0C9D6LW7Y

After I tapped the wires, I taped it up separately, with some 3M electrical tape before taping all of them together.

One more way. In the link sau gave above, the user openwide gave some details about buying a plug\parts that can fit into the blue connector.

I'll start with the parts that are needed.
Pormido Hardwire kit: LINK
Toyota F-Connector Housing: LINK
Female Pin Connector: LINK

On the blue accessory plug, there are 3 wires that goes into it with the orientation being: BLACK (12V Always On), PINK (12V Ignition), EMPTY SPACE, and then WHITE w/ BLACK STRIP (Ground).

On the Pormido hardwire kit, there are 3 wires: YELLOW (12V Always On), RED (12V Ignition), and BLACK (Ground). The yellow and red wires comes connected to fuse splicing connectors, and the ground wire has a grounding terminal. Cut off all of these things from all three wires. And then attach the Female Pin connector to each wire.

Test fit the empty F-Connector into the Blue Accessory Plug and make note of orientation of the plug. Now take the Pormido hardwires with the newly attached female pins on, and push them into the F-connector in the same orientation as how you want the wires to match up with the wires on the Blue Accessory Plug. YELLOW (hardwire) to BLACK (blue plug), RED (hardwire) to PINK (blue plug), SKIP ONE SPACE AND LEAVE EMPTY, and the BLACK (hardwire) to WHITE/BLACK STRIP (blue plug).

Plug everything in and now you're done.

Goodluck with everything. It was fairly easy and straight forward. I wish someone had written up a detailed instructions like this when I was doing it. I had to piece meal together from a bunch of different posts on the forums to figure everything out. Cheers!

From your pic, you want the bottom black wire hooked to the white\black. The bottom red to the pink\red.
