More guage questions?

I am in the process of trying to install my new EGT,boost,and oil pressure guages.I have a couple of questions about my EGT gauge and my oil pressure. The oil pressure guage is mechanical so I am looking for a convenient place to take my measurement. After looking in the FSM it says that to check the oil pressure you use a mechanical gauge and use an existing location on the block beside the sender(round device threaded into the block with wire coming out?). On my 12-ht I cannot see a threaded hole beside the sender, not even a plug to remove. Has anyone installed a mech oil pressure gauge on either a 12-ht or a 2h motor and can give me a location of where to tap into. Beside the sender is a flat spot that might be used for a oil pressure port but it looks as if it was never installed.

As for the egt guage it uses 12 volts to take the temp readings and was wondering if I use a 24 volt relay tied into my ignition and 12 volts from my converter to power the type k probe will this work and give me an accurate reading.

I am going to use the 24 volt relay method as well for the lighting if I cannot find 24 volt bulbs for the gauges.

All my gauges are autometer if that makes a difference.

One last thing can I take my boost reading from the tubing that goes between the intake manifold and the boost actuator or do I have to tap into the manifold from the turbo to the intake.

Thanks guys for all the help real new at the diesel stuff.

You have to remove the sender and screw the test gauge in there

you can install a "T" and install both the mech and the elec.
tie into the converter for the 12V

Thanks for the info, I had thought that would be the way to go but wasnt sure and i definately will be putting in a tee so the factory gauge still works as well.

Isspro makes 24v gauges if you can exchange yours. It might make the install simpler and cleaner. My boost is off a "T" on the wastegate actuator.
