Anyone know of a good place to pick up a switched wire to use as a trip for a relay on a 2012 or up JK? Wire needs to be under the hood and hot with ignition.

 

I used a piggyback plugged in to one of the empty seat heater sockets in the fuse box. I dont have heaters. I drilled a hole the same size as the wire to come out of the lid then sealed it with some rtv. you can also tap in to this wire from below but it is some work and I dont know which wire for a '12

 

OK, thanks. I'll take a look as I don't have heaters either.
