Installed my Autometer gauges this weekend. Had some questions along the way and found this article with pictures that answered all my questions.

Only PITA was I didn't realize in advance I was going to have to drill and tap my intake, so I didn't have the extra fittings around. The Autometer boost guage only comes with one '1/8" FPT to 1/8' compression" fitting which you can use on the back of the gauge... if you'll be tapping into your intake elbow be sure to buy a '1/8" MPT to 1/8" compression' fitting also.
Tapping the exhaust for the EGT was much easier than I expected. Put a bunch of grease on my drill bit to catch the shavings and it worked great. Followed up with a shop vac just to be safe.
Best of all was learning about the blue wire with red stripe to tap into for the backlight on the gauges so they all dim with your factory gauges. I'll see if I can post a pic when I get home later.
