OKay, I dont' know much about gauges, and the truth is, a friend is installing it for me, but still, I would like to know of the best place to tap some of them.

I have 4 DEFI link guages,
EGT
BOOST
OIL pressure
Fuel Pressure.

I was already told that the best place to tap the EGT is on the 3rd runner on the manifold, or if you paranoid, you can do it on the downpipe.

I don't know where the best place to tap the other ones would be. I don't even know if there are more places to tap them at all? I mean, I donn't know if there is only one place to put a tap for the boost guage or not, hence me asking these question.

Please let me know.. Thankyou.

 

EGT - #3 runner, 1.5" form the head

BOOST - tap it to a source that has the shortest distance to the intake manifold

OIL pressure - run a tee on the back of your block, you'll run the oil press gauge and stock oil press sender

Fuel Pressure. - on top of the fuel filter, or if you have an aftermarket fuel rail and external FPR ( like paxton) you can place it on the fuel rail itself or the FPR
