Hello, New guy here.

Have a 2014 Accord LX that I want to hardwire the radar detector and Garmin into the fuse box under dash.

Any input into which unused terminal is hot when the ignition is on ?

Also, in a car built mostly of plastic, any underdash metal grounds ?

 

Based on the circuit diagrams, slots B3, B4, B11, and B18 in the under-dash fuse/relay box should be empty. They may or may not have wiring connected in the back of the fuse box for those slots.

You can use an "Add-A-Circuit" in one of the unused slots in the driver's side fuse box or tap into a used fuse slot to run power.

You should be able to find some metal ground point under the driver's side dash. Many times there are already bolts or an existing hole in the metal where you can add a bolt, washer, and nut.

 

Thanks Redbull, I like the mini connector , off to Radio Shack !
