ask and ye shall recieve...
I was prepping my car for a turbo so I installed an electric oil pressure air/fuel and water (to hold a spot for the boost gauge when ready) but Ive since decided to stay NA and just go for a motor swap. Any who yes Ive installed them and it can be a pain. The most annoying thing I ran into was having to lengthen the I/O/S wire from the oil pressure sender. Not much space to work in so it was a bitch to get at with a soldering iron. Id recommend that first you go down to Radio shack pick up the wiring and some wire loom set up your new wiring harness and then go to work on the senders. Give yourself the weekend to do it.
