Wow, SnapOn USA....
Good find. lol
LOL, yeah. Cleaned up and in with all my other bits now.
I can't see the pics where I'm at right now, but I find it hard to believe that the signal you got from an oil pressure sender would only give you enough to show if there was pressure or not. I think something is a bit messed up on that. Are you using a Defi sender and gauge (remember, can't see pics)? What pressure range does the sender detect?
I used the location that NewSouth recommended. I did use the Defi sender and gauge, it's got for up to 10bar. I get more than just a yes/no pressure read, on startup indicated pressure is 4.5bar, once the oil is warmed and the car is idling, pressure is down to 2.1bar, and whilst driving around with warm oil pressure sits at between 3-4bar. Somewhat useless to know but nice
