ground it and then wait , that will make it a little safer,
wow your up early also,
you could pick up a supply of the wire nuts they come in multi packs for different size wires , if your out to day , but didnt Av8tor say he was sending you something, might want to wait on that as well (if you can wait ,I could not )LOL
Im in lab today so cant do much till late this afternoon or this evening. But he's going to go by lowes and get what he needs today.
and yes french, if you use the wire nuts the yellow connectors will have to be removed.
Basically slide the romex box adapter over the extension cord first (remove the round nut from it first). Slide the wires through the access plate next, and then slide the round nut over the wire. Now trim back the wires to approx 1/2" or so. We don't want too much bare wire or it will protrude past the wire nut and be unsafe.
Next, hold all the ends of the wires to be connected together with the ends even. Some will tell you to twist the wires together prior to screwing the wire nut down. I prefer not too, let the nut do the twisting.
Place the wire nut over the bare end of the wires and start twisting in a clockwise rotation until it gets good and tight.
Now, tug on each wire just to make sure they are secure, sometimes you will miss one in the process or just barely catch it. Always verify with a good tug on each, don't forget to do this.
Repeat this for each group of wires... the blacks and the whites in your case.
Also make sure there are no loose strands protruding from the nut that could short out on something.
Now, makings sure you have enough slack, slide the romex adapter down into the knock out hole and tighten it to the cable and to the access plate
Confusing I know, but it will be so clear after you do it just once...
Ill take pics tonight for ya

The gray with red swirls is probably for emergency lighting, occupancy sensor, dimmer (yes, some are dimmable now) or some other accessory. It will definitely not be a ground. But what it is I cant tell you, but if you look on the label of the ballast it goes too, it will have a schematic.
Those lights do have an emergency light connection (I THINK)... but verify, you may want to just tape that one off... I just cant tell ya without looking at the schematic.
My gut tells me you wont use it, but verify mate.
Now that you have the romex connector, does everything make more sense?
excellent, and no more scotch tape this time either k
use good electrical tape mate, I like 3M brand personally... just not dollar store stuff :P
sounds like you have it all under control now
Edit: French, one statement you made gives me the impression that the gray with red tracer was connected in with a white wire at the original yellow connector, if that is the case then just repeat that with your wire nuts.... that may be the default connection if you dont have an external emergency lighting control circuit.
hope that didnt muddy the water again :P
either way, the schematic should tell you what to do with it
Ahh Well I wish I would have read the edit before I finished, no matter though I did just that once I figured it out haha. It was actually connected with that black. I left it out at first and plugged everything in and 2 bulbs didnt light up but when I put it in with the black it worked.
I've got 3 blacks (2 from ballasts, 1 from extension cord) and 1 grey wired with a wire nut and 3 whites (2 from ballasts and 1 from extension) wired with a wire nut. The ground wire from the extension cord is attached to the access plate using the green screw on the back. Here is the finished outside look. ( I was too into what I was doing to remember to snap pics of the wiring completed before I put everything back in but if for safety it's needs to be done (double check) then no problemo it can be done.
