DigiPanel Oil Pressure Sender

[ree.eric]

Installing the digipanel and I find a sender that I believe came with the kit. It is a 3 pin unit (PS140T) but I don't know what the connections are.
Couldn't find the specs online even though it is available everywhere. The stock one is 1 pin. Should I use the stock one with a T wire connector? Is
there only one place on the engine for an oil pressure sensor?

The oil pressure sender that came with my DigiPanel was a single connector. I believe it is a standard 90 ohm sender. I'm guessing a 3 pin sender
would be a 0-5 volt output.

You can't simply "T" into the existing sender as there is a load resistor in the Digipanel. You can order the Digipanel with an option to "T" into the
sensor wire. If you don't have that option, both the Digipanel and the dash gauge will not read correctly.

I understand that Applied GMC now owns Digipanel and they may have changed the circuitry so requiring the 3 terminal sender. The Digipanel manual
should show if it is one wire or 3 wire sender.
