Looking to find out if anyone can help direct or suggest a few very good areas in a 94 k3500 6.5 turbo diesel to get accurate readings for aftermarket gauges as my stock cluster is not accurate and some of the gauges from the stock cluster dont work.
i have

water temp.
volts
oil press.
trans. temp.
egt temp.
air/fuel

i already have the boost and fuel press. bolts to make it easy to get a reading on those two

i just want to do this once and get the most accurate readings to monitor the truck without hacking it up at all

please let me know thank you
 
WT from head.
Volts from alt.
Oil psi from OPS (tee).
trans from pan or inline.
EGT from pre turbo. Under turbo on manifold is a little cast in square pad, makes a perfect spot.
 
On the transmission, 4L80E, there is a pressure test port with a plug in it on the driver side above the pan on the case. Near the shifter. The trans temp probe threads into hole for a painless install. Used that location forever and it's fairly accurate.

ok thank you leroy
for the water temp. where exactly on or by the head would be the best place to get a accurate reading

There really isn't an accurate location. There is a cold and a hot location - GM used the cooler driver side front head for temp. Hottest is rear passenger side head due to lower coolant flow in passenger side block. For some reason the rear of these engines run hotter.
 
most engines run hotter against the transmission and away from water pump. Trans body holds in the heat and water pump is the thermal exchange point so a lot of heat is lost there.
 
I got all my gauges from EGauges. They were priced fairly and had a huge selection. My main goal was to have all my gauges match.
I have a write up on here some where on my install.

From the original post, sounds like he already has boost and fuel pressure hooked up.
