Oil Pressure Sending Unit Plug

I was removing the rear hoist bracket to install a fast 102 and I accidentally broke the 3 pin female plug that goes into the oil pressure sending unit. I found a replacement plug at parts geek, but the wires aren't color coded like the factory three wire harness. There is a green wire, a yellow and green wire and a brown and white wire. I need to know which wire goes to the single plug that is closest to the snap connector, and also which ones go to the bottom left and right connections. Any help would be greatly appreciated as this is not covered in the shop manuals. Thanks in Advance!!

Oh this would have been so easy last week when I had the top off my engine. I'll see if I can find out.

I made my best effort. If you had asked last Thursday I could have easily told you. My FAST manifold almost covers it and I tried an inspection mirror and squeezing my hand back there. No go. Sorry.

At the plug, aren't they laid out flat left to right, 1-2-3? Can't you just match them up as they come off the plug??
