06 4.7L won't start; Please help.

So over the past few weeks I have been taking apart my 06 4.7L 2WD Limited, dash board to change the heater core and fix the broken gears on the blend door acctuator. I got everything back together, except the steering wheel. I was super proud of myself because I didn't have any left over bolts or screws!! The I realized, I have an extra plug, not plugged in. And have no idea where it goes. I have been searching for a wiring diagram, but can't find one I understand. Under the steering wheel, it's bundled together with the wires that connect to the foot light, it's the only other set of wires on that branch that exits that part of the harness. I tried to post a photo, I don't know if the black connector tab is hooked to the right place. Anyone else have this version that might be willing to look under the steering wheel and see if you can tell where this plug goes? It's a grey connector with a blue wire and a black wire with a green stripe. I see a similar one on the HVAC housing in the right rear corner of the steering wheel opening, but I don't see another spot for this one. Hubby said maybe it was never connected to anything but I don't remember a free plug here, but then I took it all apart about 3 weeks ago.

Ok, I'm an idiot. Ripped everything back out except the dashboard and gear shift box. Contorted in a million different ways with my little mirror to figure this out. Finally, looked at the connection in the back right corner, the one that looks identical to the one in trying to place. For the hell of it, I put my mirror under it. It's a 2 slot recptical. One goes in the top (the one that is there,) and one goes in the bottom, the one I couldn t figure out. I could punch myself.

Well, still chasing my tail. Not sure if I should start another thread, or continue this here.

After I got the dash back in and the steering wheel back on, I replaced the starter that was giving me problems before i did the heater core.

Whoever serviced the starter before me fixed the "yellow wire" problem by silicone-ing the connecter to the bad starter 😞

So, I made a new connector and added a little extra wire (BTW it's 12g wire not 14, I couldnt find that info anywhere and the one place i found said it was 14g, but none of the 14g items I bought would fit)

Hooked up the battery, still won't start.
Swore, pulled a little hair out, got back to working on it. Wouldn't even crank.

Problem was the neutral safety switch doing its job. in the shifter gear box area, shift indicator was reading 1st gear no matter where the knob was set. Re connected the shifter cable in the plastic nozzle thing that some how came undone (I think when we took the dash out that cable was hung up and hubby yanked too hard) got that all fixed, now shifts fine and indicator is reading correctly.

Tried to start, will crank but not start, it even started for a few second initially (probaly used up the fuel in the lines?)
Fuel pump is engaging, I checked the fuel pump relay, it's working fine. Now I'm at my limit of knowledge. I don't know what to do from here. I'm worried it's an engine issue, hubby thinks it's something to do with the anti theft or ignition stuff. Im having it towed tomorrow night to a repair shop for diagnostics and fixing on Wednsday. But the stubborn side of me wants to figure it out.

It ran ok, other than the starter issue before I did the heater core.
It does have a slight overheating issue (why I started with the heater core, I'm trying to get the whole system corrected) but it only overheated to the red once, we had it towed and compression tested and everything checked out. Needed new hoses, so the previous shop did that.

I'm bummed because I got new headlights, foglights and rear glass lifters and hubby won't let me install them untill it's running, so I can return them if this is the end of our commander 😞

Already shopping for a new one, because we want a second one anyway. They are very underrated, in my opinion. They are a great vehicle.
