TOPIC: Bearcat 55 wiring hookups

Good day to all, I have had my bearcat for about 5 years and never have had it running. I am attempting to do so now that I finally have it mounted on a boat I have been building for 6 years. However I am not sure I understand what the wiring hookups are and especially how the motor control box ties in. For instance I would like to hook my helm instruments and run wiring but not sure on the temp and oil press since the senders share a common wire that apparently goes to the control unit at the helm? I dont understand the connection. Any feedback or clarification would greatly be appreciated as I attempt to prepare for test running this motor.

Talked with Bill Roberts this morning and he helped me sort out the wiring and a few other questions I had. Thank you Bill. On my way to getting this old motor going.
