someone suggest get a t piece and fit it in along with the warning switch on the blosk but were is that?

 

Oil pressure sender is under the alternator at the front of the engine.You will haver to move the Alternator out of the way to get easy access though

 

fitted mine via a remote braided line, bought from demon tweeks, screws into the block under the alternator and has a tee on the other end to fit sender and warning switch into. two lengths available so you can fit where you like. (may need to earth sender seperately though)
