What oil pressure gauge??

[TSiAWD91]

Ok im looking to buy an oil pressure gauge.I just bought a A-pillar dual gauge pod,and i need something to compliment my boost gauge.So i decided to go with an oil pressure gauge.My question is do i go with the electric or the mechanical gauge?i would prefer the easiest to install.and where does the sender hook into(where is the oil pressure sending unit)?thanks for any help!

i am going to purchase the oil pressure autometer phantom gauge. you should also look into a EGT gauge.

check out optauto.com
they have the lowest prices on stuff and they send pretty quick.
