Hardwiring issues - ignition switched 12v

[Justin Hawkins]

I'll have to post a pic this evening when the Tahoe and I are back home.

Great! I am cool with the routing of wires. That's not the issue. It's all about the power!

You're just going to need to go down there and test the harness pins, it's not that hard.

Cool.

Here's what I have:

Three white connectors, go to the topmost one...

Heavy black wire is ground, small white wire to right of green wire is switched 12V+.

You got it! (With your fancy-schmancy pic labeling )

You got it! BTW, I recommend checking the wires with a DVOM to confirm they are what you need if they're different colors in your truck than they are in mine. I also don't know what 12V+ circuit that is or the ampacity of it. It's not much of a concern with just powering a radar detector, but I'd like to find out one day.

I will use my multimeter before I do the install and check those and report back.

I checked the ground with continuity (obviously) to a door hinge bolt or something like that in the area. For that switched hot, I made sure it was no voltage with the car off, battery voltage with the key "on", and 14.xx with the engine running. It's definitely not a data circuit!

Hi all I’m wiring up 2 DVD players to the headrests of my 07 Yukon Denali. I’m not sure what I should tap into for wires. I would like for them to shut off when I open the door just like the radio does. Don’t want to have to worry about my kids turning them off. Any help would be appreciated. Thank you

Under dash to left of brake pedal is a black cover there is fused, switched, acc, rap all right there..

May not look exactly the same but its there.... just use a dvm to verify

I went back through and read everything more carefully. Such a big help. Thank you again

A year old thread, I know, but......

I'm wiring up my dashcam which uses a 3 wire hardwire kit that senses the accessory power turning off to enter parking mode
- ground
- constant power
- switched accessory power

The ground and constant power is no problem. I'm guessing I should use one of these RAP (retained accessory power) locations so it won't go into parking mode until after I get out of the car?

Old thread, but the issue is still relevant. I didn't want to run a wire to under the hood and no hot wire ONLY with ignition on is available in the driver side fuse panel on my 2010 Tahoe. I ended up wiring my dashcam to an open pin next to the brake pedal.

Why the hell isn't this a sticky!?

Thank you so much for making this reply. It's exactly what I was looking for to avoid splicing into another wire/under hood route! I'm doing the exact same on my 2013 Avalanche after testing voltage this morning.

is that terminal RAP (retained accessory power)? or just acc switched

 

[gooffeyguy]

I believe there is both down there. In each of those plug recepticals there should be a ground, constant+, switched+, and RAP+

 

[j91z28d1]

interesting. I may poke around.

For perspective, rotate diagram 1/4 turn counter clockwise. Pins on the left side (top in pic) 1 starts at the inside top, then 2 inside bottom, moving outward top to bottom.
