Today I spent half the day looking for which wires do what on my new to me 2017 Ford Transit 150, (I also discovered that there's no pats ring on mine) and found some discrepancies from the chart posted in the wiring diagram page (Listed under 2015 I believe). I don't know if anyone else has discovered this or not but I will share what I found.
I started with a Multi-Meter but then switched to my Power Probe III, easier to understand/read in my opinion. A "Short Cut" I did while testing with the power probe is once I found one of the wires I was looking for by Probing each one with the headlight switch turned on, when I found a wire that was hot I turned the switch off to verify the correct functioning, after I verified it was the correct wire I back-fed it with the power probe with the switch off to see which side it belonged to, same thing with the parking lights.
First the BCM/Fuse panel referenced for the wires has 4 plugs on it, molded into the casing body by the connectors it has "C1 Black", "C2 Brown", "C3 Brown", & "C4 Blue" and the diagram page only has "plug B" and "Plug C" which is inaccurate and for me confusing to try and decipher.
Second the category for Headlight on it is actually the high beams (It does have the note for that by the wires but it should be on it's own line not under headlights.
The actual Headlight wires (on my application/vehicle) were C2-Blue/Green (Right side/Passengers), and C3-Brown/Blue (Left side/Drivers)
when I tested the parking lights I discovered that C2-Green/Orange was both the drivers (Left) Front AND Rear, and C3-Brown/Yellow was both Passengers (right) Front AND Rear. I didn't think to test the turn signal switch once I found those wires to see if it was the turn signal wires or the park wires, but my dad said it was the running lights when I back-fed them and he looked, but I doubt he would have mistaken that.
and as for the Wipers that was C3-White. I don't recall the operation, I think it was powered while off and grounded when activated, But don't quote me on that.
If I recall correctly the parking lights and headlights read ground until power was applied to turn them on (I know the head lights (low beams) did, I made note of it). I don't remember how the high beams acted.
I did not go and double check the whole diagram on the site for accuracy but I did for the wires I was looking for. Now that I have more of an idea of where what wires are, after I get the rest of what I need, I can go in and try to install everything at once, in-fact I'm thinking of adding a remote start kit from 12volt solutions (or Compustar CM7000) to the mix too. However If one of you guys (Musty / Kreg) want to come down to Florida and do it for me, I won't object... lol, I've about had it just trying to find the wires, I'm dreading having to go in and connect to all those TINY wires in that confined space.
I was looking at the install instructions for the Compustar CM7000 and I see in the options there's an option to turn off the security features, I'm sure it's dumb to get it and only install half of it just for remote start when I could just get the 7300 (I think, Maybe it's the 7200, Either way...)unit instead. Question on this is what all would I HAVE to hook up just to have the remote start work using the factory Keyfob (hooked to the horn wire, I forget what they call it "Trigger Input" I think), or should I just bite the bullet and do the whole alarm and starter then in the future it's just a simple option change to have the full system going? and should I get the AL Blade (Bypass, but not used as a bypass) thing for the doors and such or would this unit handle them, I'd seen a note about using PIC wires for the N.C. Wires in place of diodes and relays and such towards the end of the booklet...
