retrofit power seats into 65 Mustang

[mwhit69]

I need a picture with which connector is the positive and which in the negative going into the drivers side memory module for power to the seat. I am putting 2004 XC90 power seats into my 65 Mustang. I have figured out the wiring for the power passenger side seat but dont know which plug on the memory module is the positive and which is the negative. Can you please help with a picture and the + - symbols? I have the wiring diagram but am unable to decipher the information I need. Any help would be very much appreciated. Thank you.
