So lets not argue about positioning for now. This post is more to post about the wire run location and what fuse #8 can do for you - see below . ..

Next I hid the wires in the trim along the door jam down to the fuse box (see the pictures). The trim just folds away and you can tuck the wire behind it for a clean look.

Then I used the "un-used" fuse slot #8 to provide power. Yes, this slot will provide power - not sure why Honda is not using it - probably for another feature I don't have (maybe the Auto dimming mirror?)

Turns out the #8 fuse slot is controlled / switched by the ignition switch, so my detector is only powered on when the key is in and the engine is on (just the way I want it) .

When you tap the #8 fuse, the lower part is the positive / power output, so your wire should tap the upper fuse slot (so your fuse, will "fuse" the detector/powered device). My detector uses little power, so I used a 7.5 Amp ATM fuse.

Also, found out the fuse slot #7 is always powered on so keep that in mind for other projects where you want constant un-switched power.

There is a Phillip's slotted bolt/screw (not pictured) that holds the fuse box to the metal frame (to the top right of the fuse box). This bolt is a perfect ground for projects like this. I used a "C" shaped quick connect for the ground wire from the detector here - works nice and is out of the way.

FYI,

Wally





is slot 8 still "un-used" fuse for 2009 Si sedan? I try to use this method to hardwire my v1
