Well that was fast... Kit’s already here!
Only got 1/2 way through installation over an extended lunch break before I had to head back into work. Friggin’ interior upfitter wires are still playing hide and seek despite me opening ~8” of the harness so far.
Under hood connection was easy enough (I chose Aux 6 switch; green with orange stripe on my ‘18):
I used my own (doubled up) heat shrink, though it was included in this extremely well though out kit:
Heat shrink on, and remaining wires tempoarily zip tied out of the way:
I’ll rewrap them if I wind up not fitting lights soon.
Really having a difficult time finding the interior connection point (‘nub’ end of the upfitter wire). I’ve gone from the plug in connectors all the way up to where the wiring harness goes up behind the dashboard and no joy so far. I even took out the glove box to have better acceess. I can see the wire in the harness/loom, but so far no end piece to tie into like there is in the engine compartment. So close to finishing as the kit is laid out very clearly and the relay itself is very easy to install, but the damn wire loom installers at Ford are making it difficult.
Will take pics of that tomorrow if I get home from work in time...otherwise this weekend. For those who have installed on an ‘18, was the ‘nub’ end closer to the fuse box end or way up above the glove box?
I may need a resupply of that last tool required in the instructions!
