I am hardwiring a radar detector using a "add a fuse". 2013 focus. Its the type that you take out a fuse, insert the original fuse in the new holder, then add a second fuse for the new item you are wiring in the second fuse position.
I tried fuse 69 (instrument cluster) and fuse 73 (data link connector). In these positions, my radar detector is on all the time with the car shut off. I want it to only come on when the car is on. Any idea what I am doing wrong?
Thanks
