Quote »yeah, basically, you T-off the pressure switch, one going to the switch, the other going to the sending unit for the gauge[/quote] I didn't T-off anything. I just removed the old pressure switch and added the electronic sending unit of the autometer oil pressure gauge kit. You now have a new responsibility and that's watching your oil pressure, instead of looking for the little silly light because once you see that light come on a with a turbo engine, you've already done some damage. And in case any of you didn't know, a performance engine seems to run its best when it's low on oil. Don't ask me how, but every engine from the SHO yamaha motor, 4G63, CA18DE, CA18DET, GA16I (just to name a few) all seem to be running harder when they were pretty low on oil. So if you notice your car running exceptionall wicked after a bit of neglect, get curious and check the oil. Just an FYI........
