Accessory fuse?

I’m trying to hardwire my radar, can someone help me with which fuse to piggy back? I’ve tried a few fuses and they have all stayed on when the car is off.

Here are some in the panel that are IG on fuses (so no power when the car is off):
10A IG1 NO.3
10A IG NO. 3
7.5A METER
7.5A IGN NO. 1
7.5A IGN NO. 2

Basically any of them that say "IG" or "IGN" in the fuse name can be used.

Best recommendation is a mirror tap. Cleanest setup so far.

I actually meant to include that suggestion as well.
Assuming it needs a 12V source, much like some dashcams, you can tap it into the mirror...therefore no wires to run all over the car.

I agree. I had mine mirror tapped and it's so much easier and cleaner.

Thanks guys I’ll try out the ones you listed.

i already have the Escort hardwire with the mute button installed in the dummy mounts. Mirror would have been nice if there was no button. The fuse box is inches away from the dummy mounts.

I have a fog light switch that I'd like to put in that is roughly the same size as one of those false inserts and would want to know if it's going to be a simple install or not.
