Thread: Source of delayed-off +12V behind or around the dash

The power supply to interior lights including the glove box light are on a delayed “battery saver” timer.

Gold. 10A fused on the battery saver relay and available all over the place. Thanks!

That allowed me to narrow 200 pages of wiring diagram down to 3. Much obliged.

We’re only talking a few seconds to minutes depending on battery charge state.

Better to put the dash cam on a LVC made for them.

I was wondering if anyone knew of a "delayed switch off" source of 12V in there somewhere that stays active until the car goes to sleep?

I'm just shooting this off to see if anyone knows off the top of their head before I sit down and bust out the wiring diagrams and a meter.

Just thought it'd be nice to let the dash cam run until the car goes to sleep.

Can I bring my car over and copy you as you do it (for the same reason/s)?

That’s all I want. My second option was to put a 60 second timer on the unswitched feed. I’ll instrument this one and see what it actually does, but I’d be happy with anything > 30 seconds. 2 minutes would be cream.

I’d normally say yeah, but working around the kids I can’t guarantee any timing. I just grab 5 minutes here and there when I can. I’ll take a crapload of photos and write up whatever I end up doing if it’ll help.

On the D3 there are two types of delays. One is on the overhead interior lights which powers down after a default 60 seconds (although this can be adjusted from 10 to 240s). These are unfused and controlled by the FET’s in the CJB.

The other is the power supply to the glove box lamp, map reading lights, and mirror vanity lights which power down after 15 mins. This relay is after the fuse so would have to pick up the power feed after the relay.

Redarc makes a few timer relays, but they are not cheap. But very reliable and will get the job done. Tim05 is the part number
