    heres the short version..

    Assuming you already know where to tap in for illumination and power (Ign or gauge wiring harness)

    A/F ratio.. Tap into oxygen sensor at exhaust manifold, its a better idea to find the wire at the ecu but you can look it up if u have a wiring diagram.. I think theres one in the haynes.

    Volt: + Black/Orange Ign switch harness, - Ground (or engine ground if u feel like runing all that wire)

    Oil Pressure, 2 kinds Mechanical and Electronic.. Mechanical you run a oil line into the cabin, Electrical you run it to a sending unit then run the wires into the cabin.
    -2 Methods
    1)You can tap into oil by removing the stock oil pressure sender to the right of the oil filter and below the alternator. The sender port on the block is 1/8 BSP.. sending unit is 1/8NPT(you see the prob here) so you have to purchase a 1/8BSP (M)-1/8NPT(F) adapter to make it work.. also then you'll lose your oil light
    2)Use a oil filter sandwhich which you can pick up on ebay, it already has ports where you can stick the sender into
