Auxiliary switch question

[3500heavy]

I have a ‘21 3500 Big Horn. I’m wanting to hardwire my dash cam to an aux switch, I kind of understand what I need to do but am unsure of something. The dash cam has an acc wire, a battery wire, and a ground. I’ve connected the under dash aux connectors and I know how to jumper one of the aux relays and the pass through under the hood. Im definitely no expert as far as wiring and the question I have is since there’s both the battery and acc wires for the dash cam, how do I connect those?

Thanks,

You can use the dash pass thru battery power and then hook the aux switch to the acc power.

The purpose of the 2 separate wires is to have parking monitoring while vehicle is off. I wasn't concerned with that feature so I wired both the acc wire and batt + wire together to switched power.

Thanks, I was kind of leaning towards doing this. I wouldn’t mind having the parking monitoring but not absolutely necessary.

I also found that the camera needed the power from the batt +. I tried to just use the acc wire hooked to switched power but couldn't get the camera to work. Wired up the batt + and voilà. This was on a Wolfbox.

Did you wire both the acc and battery to one switched power?

Yes. I twisted the batt + and acc together and used a solderstick butt connector to connect them to switched power.

Hi, I just signed up to this site. I have a unique situation. I need to be able to turn my dash cam off when I come to work, be able to turn it back on when I leave. I intent, or desire is to wire directly to one of my aux power switches. The concern I have is that the manual for the Redtiger F7NP says the power input is DC 5V - 2.5A. Will I fry my camera if I wire it directly to my 12V Aux Power?

Yes. You need to get a hardwire kit for that camera. Read the manual for that camera and I think they tell you how you can get one at no cost.

What he said.

Most dashcams come with a cig lighter plug that steps down to 5V USB type power.

The hardwire kit, often supplying separate power for both battery-standby-motion-park monitor (whatever each calls it)/ignition-active states would do the voltage drop. These also have low voltage cutoff to prevent battery depletion.

I wired my dash cam in at the dome light ...there is a constant and switched power source you can use.
