Forum won't let me attach a MP4 file (too big) so I can't show how this looks on my Honda S2000. The S2000 is so little it almost disappears in traffic something the Expedition doesn't do.
Simple in-line splice of the module shown above. Mounting this on the trunk lid of the Honda was easy and I assume not any more difficult on an Expedition (although I don't have one there). A bunch of similar Hondas running around down here since a buddy made a plug in harness for them.
I think the module only works on LED fixtures like the 3d brake light in the Expedition (and late S2000).
PM me
your email and I may be able to send the MP4 to you that way.
