I plan on installing an electrical oil pressure gauge soon, and wondered what parts do I need besides

Greddy Oil Adaptor
Autometer Electrical Oil Pressure Gauge
Guage Pod

That should be it right? I don't need any special adaptors, etc?

 

If you use the Greddy block adapter, you should know that the ports come with metric threads. My autometer senders are all 1/8th NPT, so I bought a 1/8th NPT tap and re-threaded the block adapter ports.

 

The oil pressure switch port is threaded with 1/8" 28 BSP threads. If you try threading a standard 1/8" NPT fitting in there, you will strip the threads. If you use this port, you will need to install an adapter and a tee.

If you are using a Greddy Sandwich Adapter, you will not need to access the oil pressure sender port. Either way, you will need a small braided line from the adapter to the pressure sender. If you don't put this in place, vibrations from the engine will eventually fatigue the fitting to the pressure sender, causing it to crack off.

I picked up my 1/8" NPT/1/8" BSP adapter at Napa (you will probably have to order it since it is usually not a stock item) and a 12" stainless braided line from Jegs.

XViper had a great writeup on this installation, but the link doesn't seem to work.

 

Be sure to remote-mount the oil pressure sender.

 

I completely removed the stock sender and tied off the wire.

I checked the wiring diagram. It is only used to turn the idiot light on and off.
