The 3 black dots represent the splices you'll have to make into the existing Expedition inverter harness. (If you have one from factory)
Pin 4 of C2293 is the additional Terminal needed for the Dash AC/DC outlet LED indicator.

I think I may be confused. Are you replacing the existing 150w inverter with the 400w inverter and adding the dash port? OR are you adding 400w inverter just for the dash? Sorry brain on meltdown today. Where is the stock inverter on the Expy located?






Great! Thanks!
#1 where is the inverter located in expedition?
#2 how'd you get black interface on Sync? Is that 3.4?

Exactly, I replaced my Expy’s 150W with the F150’s 400w inverter.
Replace my 150W Expedition Inverter with the F150's (400W) dual AC Outlet. The Inverter I bought on ebay came with pigtails. I made my own Harness adapter so I wouldn't have to cut into the existing Expedition harness.

The Inverter mounts behind the Dash on the driver side. Full Disclosure, this is an awkward spot to mount anything in but it can be done with some conviction. I used short self tapping screws.

The opening for the AC outlet required some sanding to enlarge it so the F150 Outlet would fit. Made an extremely big rookie mistake ... I forgot to use masking tape around the edges, now i'm left with some scuff marks. Learn from my mistakes
I used a flat wooden stick (paint stirrer) with 180 & 320-grit sand paper. The areas I focused my attention on were the top, bottom and right sides of the opening. More so the top. I ended up having to sand the bottom left corner of the AC Outlet also to make it fit.
Could've done without the scuff marks but I'm happy with the results.

@TXFRDOwner
It looks like I have this big connector, mine is green rather than gray, but is that what the inverter is getting power from?

yes, the gray one is the Expedition's original inverter connector ... I made the pug-n-play harness to piggyback off of it.

@TXFRDOwner where are you getting all these awesome wiring diagrams? I may be in for a bigger chore than I had hoped if it ends up I don’t have that inverter pigtail. I’m going to tear into it this week more thoroughly to check for sure.
I purchased a 5-Year subscription at Alldatadiy.com for the 2015 Expedition Workshop Service Manual.

even if I don’t have the pigtail I think I’m arrogant enough to try. I bought the allsatadiy subscription, figure I’ll use it for other stuff, too. My biggest question is, does the splice for the inverter coming off the main harness have the same colored wires as the main harness? I’m having trouble finding that info based on what I’ve seen thus far on the website. I’m having some difficulty navigating it, and, more often than not, stumble upon what I’m looking for rather than where I would logically think I would find it.
