Your not alone in here. Was meaning to respond yesterday but family stuff got in the way. If you check out this Oil filter line diagram from our Oil Filter Tech Tip you can see the forward port location is meant for the oil return line connection from the filter. It would be blocked off if yours doesn't have a filter installed. The rear port is the one where your oil pressure gauge was and needs to be connected. If you install a filter, it will need an adapter to allow for the oil filter pressure feed line to the canister in addition to a port for your pressure gauge line. Hope this helps.
BTW - I enjoyed seeing your short videoshort videos in the GTT forum!
