Blackvue or any Dashcam hardwired on GMC sierra 1500 AT4

Yes I used a multimeter and found a always hot and a switched hot.

Ok great so this confirms there must be something wrong with my fuse box since I cannot find a single hot fuse.  I’m grounding my test pen correctly to the frame of the truck.

weird home the internal components are working though.. unless the passenger side is a redundant side and they are being powered by another fuse

[Dthissen]

I would try to use the bolt behind the large connector as your ground point. If your truck runs then I seriously doubt there is an issue with the fuse panel, it’s got to be a tool or technique issue.

I’ve tried that bolt and it goes into the plastic.

on drivers side that bolt and my tool works just fine.  So I’ve tried ground to other parts including the metal frame of truck.  No joy on passenger side

[Dthissen]

That is the bolt I used for my negative. It is’ s one of the dash hold down bolts, so I’m sure it’s going into the body. Hope you figure it out.

Thanks, I'll certainly use that bolt for the negative as soon as I have power going to the fuse box.. or at least the fuses emitting voltage like they are on the drivers side

[Sachinb]

I have this posted on another thread so I'll keep it short and sweet.  It's working as even though there is NO voltage going to my pen tester whether truck is on/off, I still hardwired the BATT and ACC cables as another user suggested and the ground wire to the frame.  Turned the truck on and it worked!

I still used a pen voltage tester and still did not illuminate!!!... but again, the drivers side fuse box does illuminate (so it's not my tool)

Anyway it's working now, I'm just inquiring with another user what they use for LTE so the dashcam is constantly connected to the cloud even when truck is off so it can send parking alerts etc.

 

Thanks for your help bud

[Dthissen]

Glad you got it working. As for connectivity, when I’m driving I use the truck’s WIFI connection ($25/month is a rip off, I know) and when I’m home it connects to my home WIFI.  So it is always connected.

I just did this on my 22 LTD LTZ

F22 and F46

Do you recall which is switched and which is constant?

[AleksanderSuave]

If you're using the Gen5DIY kit, the mirror tap has a ground and switched power (red). 

 

What are you doing for the yellow/constant power from the dashcam side hardwire kit?
