REGAL A/C Question after 330 olds swap

[Tango 20]

Swapped a 330 Olds in my 86 Regal. I think I am supposed to connect the Brown Wire and The Black Wire at the computer to make the A/C work. Positions 19 and 15. But how do i count the Positions? And Small plug or Big plug on the computer ? Thanks

Sometimes, the plugs will have pin location numbers as part of the injection molding. It might take a magnifying glass and good lighting to see them.
