B&G Vulcan 7 power cable "pin-out"

I acquired a Vulcan 7 but it came without a power cable for the 4 pins on the back. The cable is available for $42 which I will purchase but was hoping to bench test it first but the B&G manual naturally does not show the "pin-out" for the plug. Does anyone have this info or have a Vulcan 7 they might be able to disconnect the power supply for and share which pin the + & - are on (red, black, yellow, blue). See image attached.

Other units that use this power cable are: Simrad B&G 4-Pin Power Cable for Go/NSS evo3 & Vulcan/Zeus3 Displays.

Thank you.

Doesn’t the drawing you attached show this?
Don, the OP is looking for the other end of the cable which the manual does not illustrate anywhere. At least, I haven't found it in my manual.

Rick, I am 700 miles from my B&G so I can't help you out.

I know. Tracing the pin out on the opposite end is as simple as doing a continuity check - pin 1 to pin ? on opposite end. Am I missing something?

I found the information late last night on another installation manual. Thanks to all who commented.
This is incorrect. Your first picture was correct pin 2 is positive and 3 is negative

He doesn't have the cable. "...came without a power cable..."
