I think this one has a bunch of connectors between the head and cabinet that need to be disconnected if you want to remove the head. Have you removed the backglass before? You'll need to do so to access the connectors in the backbox, in addition to the bolts etc for removing it as well.
You must be extra careful though, as there are 2 big connector blocks (I think they're 36 pins each) that are keyed the same way--so it's possible to reverse the plugs and do a lot of damage to the game. Take pics, write on the connectors, whatever you need to do--but be sure to note which is which. If you are unsure, match up the wire colors on each side of the connector. Just *don't mix them up*. Post here if you have any uncertainty before turning it back on. Those connectors can be a bit difficult to unplug sometimes, but don't pull on the wiring--just the housings. There's probably gonna be a total of 7-10 connectors that will need to be unplugged. Note it's not the connectors to the boards you're unplugging, but rather the rectangular-shaped connectors you'll find if you reach into the opening in the center of the backbox once you've gotten the backglass off and opened the display/lighting panel.
Also there will likely be a metal, braided ground strap that runs from the cabinet up to the backbox and gets screwed down to the ground braid (or grounded metal plate) in the backbox. Might be a screw or a wing-nut holding it down, but there should be something there. You need to remove that for transport and reconnect it once you're set up in the new spot.
And the power cord! Don't forget to pull the power cord out of the cabinet and lay it into the cut-out on the cabinet before putting the head on! I've done that more times than I'd like to admit, lol
I think that should cover everything, but again--just post here if you have any questions along the way.
Also, here's a pic of the bigger connectors i was referencing earlier--you don't want to mix these two up (they are mixed in this pic--white should have gone to white and black to black. I just wanted to give you a visual reference)
