Is this the only way to open the roof now?

It's a TE Connectivity / AMP Micro Quadlok Interconnection System (MQS). Is there a part number on the housing?
 
Pins are MQS Quadlock, male or female:

Colored wires on this 26 pole plug are always power supply, the brown ones in the opposite row the signal lines.
 
I worked at TE Connectivity factory where we make those terminals. Was heavily involved with the stamping reeling automation of those terminals.
 
Gosh. Learn something new every day.

Why are these all different prices?

Should I just buy a bunch of these or is there a difference?

Different wire and insulation barrel sizes. It's one of the first 2 depending on your wire size (mm2)

Btw, the the connectors that Robbie previously linked to would be perfect.

I do have a concern how you removed that terminal. There is a latch on the terminal that you press down with small tool and just pull the terminal out. Yours looks like you ripped it out. There's shredded plastic all over it. Is the latch on your terminal bent back, or did you destroy the cavity in the housing? If the cavity is ruined, a new terminal won't fix it. If the retention latch on the terminal is bent, you might be able to bend it back out into position and reuse it.

Blowtorch and impact wrench. :thumbsup:

I ordered some terminals and a couple extra housings just in case. They should be here in a couple of days.
