I run mine on a pipe .. a hard steel line..
and I route the line so it goes right where the original oil pressure
wire went ..
forward, then up alongside the bell housing ..
on the front of the left head.
  That way ..the sender is at the top front of the engine ..
away from road grime and grease coming off the CV joint there, if it
ever does.
  nice n' easy to work up ..being 'up inside the engine compartment'

I got my first one from chris corkin ...now I just make my own version .
on a 2.1 it's right next to the t-stat housing ..between that the bell
housing, works perfectly, is protected, and easy to get at to work on.
