Any help on this would be great. I dont know where to attach the end bit in the engine bay

 

The best way to attach the pressure sender is to get an oil filter block adapter. Basically you unscrew the oil filter, prefferable at your next oil change, and screw the adapter block on. You would then screw the oil filter onto it next. The block has two 1/8" npt male plugs that you unscrew and screw the pressure/temp. sensor into. Greddy makes one, the one I have, and I don't know if there are others out there. That seems to be the easiest way. I hope this helps.
