Does anyone know how to.install a oil pressure and water temp gauge thanks.in advance

If I can I'll dig out a thread, but basically for the water you'll need 38mm adaptor so you can cut the top rad hose in two add adapter put the hose back on at either end and screw in the sender to the adaptor, run the two wires up round the engine bay and trough the grommet near the master cylinder that pops out into to the footewell,

As for oil you need an extender kit, then remove the alternator and you'll see the original oil pressure sender, unscrew that, pop the extender in with a t peice adaptor,then one side of adaptor accepts the original sender and the other the new sender, then run the wires back as you did with water,
