window motors

[kglowacky]

1978 c10.. there is a left and right window motor. I am working on my power window door assembly (bought truck in pieces so I am learning as I go) . do both motor plugs face the back of the truck??? The motors I have , the pass plug faces the back of the truck and the drivers faces the front. I cant see how I can hook up the plug to the drivers side motor at it is very close to the inside of the front door side. Going to pull the reg and motor is there a way of identifying left from right I may have a wrong side motor installed. Thanks
