Tachometer unit Chevy k30

[nico1277]

Hello from Germany,
The repair of my K30 has progressed well. Many things had to be redone that were not seen at first, such as the transfer case, the free wheel hubs and the radiator.
The electrical system was redone, so now everything is controlled by relays.
Now I am thinking about installing a new digital instrument panel. Has anyone of you ever done this?
I have two questions:
1. where would you connect the tachometer on the military K30?
2. how is that with the fuel gauge must the transmitter in the tank also be converted?

Many greetings from Germany
Nico

No idea about the fuel gauge but the tach is easy enough, just attach the pickup wire to one leg in either alternator.

Most digital systems will either be programmable for empty and full values or they are set up for common sender sweeps.

Hello,
thank you for the answers.
With the connection to the alternator, it can only be the small pin where the diagnostic cable is connected. The cable between the thick black and thick red ( photo)?

That is the connection. It is alternating current output, roughly 14.2 volts. The frequency varies with engine speed which is how it drives certain tachometers. Dakota Digital makes a converter module to drive other types of tachometer inputs.
