Help with power seat wiring 1993-94 850

[Jimboboobob]

Hi, I am putting 850 power seats (drivers /left) in my 1966 Volvo 122wagon and could use some help with the wiring.
I was told that the seats are from U.S. 850. The date on the electric contol box under the seat is 9/19/93. They are leather and only the drivers is power.
The control has 1,2,3 and a mem button as well as 1 up, down, front ,back seat button and an up, down back rest button.

OK, My question is how to wire it. There is a 4 blade plug that sends power to the control box.I do not have the female(wiring harness) side of the plug.
My hope is that someone can tell me which of the 4 spades are positive and which are negative.
Thanks, Jimboboobob

The 850 manual posted at the top of this forum has a section on the 850 power seats, including a wiring diagram and pin-out of the connectors.

"seats power memory.pdf" looks likely.
