CLEAN INSTALL - Hardwire Dash Cam (Front and Rear) + Radar Detector in a 2017 Audi A4 (B9)

[@migsman222]

Finally got around to hiding the wires after hardwiring (used your video in conjunction with Google to do that - super helpful). Something I found very helpful is that when you take off the cap over the lights/mirror towards the back side there is an opening where you can easily shove any extra wiring. Mine was too long by a lot and that was a perfect place to “store” the excess. Helpful video as always - glad you’re around so I have videos for all the stuff I’m doing with my A4!

thank you for this video, i have an Audi A4 2017 also and i was going to pay someone to install my dashcam (hardwired). This saved me so much money, it was "sorta simple" and took me about 2 hours. Front and rear cam. thank you!

Same

[@nicko7238]

thank you for showing me how difficult that is, you actually just saved me from a lot of trouble! I'll just stick to the 12V cord hanging off the middle of my windshield.. lol

[@DIYDetail]

No problem! It’s not too bad if you’re willing to spend a few hours stuffing the wires (you could pull the trim but the clips break very easily so you’d have to find replacement ones haha)

[@rayhernandez4507]

Thanks for doing this. I'm about to install one and this will be helpful.

[@DIYDetail]

Glad to help!

What a great video. Solid job. Gotta learn how to use the fuse box!

[@czitowyludek]

Thank you for the vid, it's very useful!

[@hanyangxie4730]

Thank you so much, I am going to try this tomorrow with my car.

[@DIYDetail]

Good luck! Hopefully it worked out!

[@bolywoodsmile]

Thanks man, great video. Was watching this as Im prepping to hardwire my 4k VIOFO im my A4 B9 Avant. Im in the UK but this still gives me a general idea.

[@DIYDetail]

Glad to help! Wiring is pretty straightforward, hiding the wires was the biggest pain given how tight the space is

[@imthestighonest3437]

You may want to redo the wires on your drivers side a polar you have run the wires across the airbag and it will not deploy properly if needed

[@thechumpenify]

Nice job, this gas given me a few tips.

[@texasbrotherhood3930]

Thank you for making this great video

[@DIYDetail]

No problem! Glad to help

[@texasbrotherhood3930]

@@DIYDetail Are you located in the tri-state area? I just bought a Uniden R3 and I’m confident I can do most of this install except for the fuse box part. Do you know of any shops that have done this type of install on B9 A4s? Thank you

[@DIYDetail]

Yeah! I’m not 100% sure if they’ll be able to install it but I think they can. Try calling Eurotech Motorsports in Mahwah or Quattrohaus in Newark

[@texasbrotherhood3930]

@@DIYDetail I appreciate it man!

[@LA-rl1lu]

For the constant power fuse for the interior lights that you used for the dashcam, which fuse number in the middle fusebank is the correct fuse? Did you also tap a fuse for switched power for the dashcam?

[@itskendyz_4534]

What about the battery wire for the dash cam? I only see acc and ground?

[@creationsmv6201]

Why you not connected dashcam to doom light, it is easer way or not? And acc you could take from rain sensor

[@texasbrotherhood3930]

I’ve been trying to follow this video step by step, just wanted to clarify on something. You lost me a bit at 9:03. Where did you run the wire when you got to those mirror electronics in the middle? Under the top clips or under the whole housing? Thanks again

[@DIYDetail]

I ran the wire through the headliner (not through the housing). You can run it through the housing but then the wire gets crimped when you put the cover back on. You can slightly pull the headliner down and stuff the wire all around the mirror housing

[@texasbrotherhood3930]

@@DIYDetail Perfect, thank you for clarifying much appreciated 👍

[@secureajs]

Where would i put the fuse if I want constant power please

[@dhardison]

Good info. Thanks

[@DIYDetail]

No problem, glad to help!

[@sjp230]

What fuse did you use for the radar detector? I have a S5 and was trying to use the fuses up by the dash and they wouldn’t turn off with the car. It stayed on at all times.

[@DIYDetail]

Hey! I tapped into the Homelink fuse under the dead pedal. I had the same problem when using the side panel fuses. I haven’t had an issue so far with the Homelink fuse

[@sjp230]

Yessir, home link was the winner. Great vid

[@olzzzzzz5847]

Thx for sharing. What type of fuse tap did you use for this specific car (I have a 2019 Audi A4, I assume it is similar)? ATC, ATS, Mirco2 or Mini?

[@DIYDetail]

No problem! These are Mini’s I believe

[@tejapemmaraju8858]

need you to help me out with this on my car!

[@DIYDetail]

Got you, no worries!

[@toddbrewer339]

Why would you want your camera to have constant power without keys? Wouldn't it drain the battery?

[@DIYDetail]

For parking mode (it’ll record while the car is off). The camera uses very little battery when the car is off (roughly 3amps). There’s a built-in voltage detector so if the battery is less than 12v, it will automatically turn off without damaging the battery.

[@creationsmv6201]

Someone knows the model of rain sensor connector?

[@sebastiantu6212]

Why not hardwire into the mirror with wiretaps?

[@DIYDetail]

That only allows the camera to be on when the car is on. You need an active 12V source when the car is off to use parking mode

[@domigashi]

you talk way too much instead of explaining properly

[@DIYDetail]

Thanks for the feedback. Apologies the video wasn’t clear, I tried my best given how complicated this wiring job was
