73-87 Diesel Warning Lamps

[hatzie55]

I am presently working on the wiring etc to install a 6.5 NA engine in my 76 K20 Silverado.
I'm replacing the 76 mechanical oil pressure cluster with a 78 that has an electric pressure gauge and a Tach. The Tach and Speedometer each have 2 warning lamp positions at the bottom rather than the single "BRAKE" lamp in the 76 cluster...

BRAKE is a must keep... I would like to put both diesel specific lamps in the cluster and keep the 4x4 indicator.

In the 82+ 6.2l rigs where are the "water in fuel" and "wait to start" lamps located?

External to cluster--in bezel. Two 1/2in squares of red.

Are they all there or just the medium duty C40-80 trucks?

All of them. WIF is red, GP is amber.
