I can't help you with a video but here is a short write up.
For your oil pressure gauge I will assume yours is electric since the last set of glowshift gauges I installed was. Now, before we start more than likely the oil pressure sendind unit isn't going to thread into the oil filter housing, it will start to thread but will feel like dog sh*t with every turn. The reason is that the ofh is pipe thread, meaning it tappers to seal. Before you start your install you should either source out an adapter or a tap to thread the hole in the ofh.
With that out of the way... decide where you want your gauges sitting and look to see what hole are available to run wires/hose through. Your oil pressure gauge is going to need a 12v power source, any keyed source is fine to tap into. You will need to run a single wire to your oil pressure sending unit. Look on the fire wall under the dash and look for a plug or rubber grommet hat you can poke a hole through and run your wires. Just be sure there is something to protect the wire from bare metal.
For your boost/vacuum gauge it only requires you to run a hose to a vac/press source, on your throttle body where the vacuum lines are connected are 4 ports, t into the port labled P.
For your lights what I usually do is find the connector for the dash light dimmer switch and tap into it. That way your gauges dim with your dash lights.
Ah crap, you probably have the gauges that you can't see through without being lit. In that case, same 12v source as your oil gauge. Hope his helps.
