1974 Scamp #2

Hey Brain, I do not have that wire harness on my 74 Scamp nor do I have that relay or what ever it is that's bolted to the fire wall. I do know that the black plug with the two connections right in the middle of the picture hooks up the drier bottle for the A/C mine hooks up on the passenger side of the car and it is located on the outside of the radiator support right between the condenser and the passenger side headlight. Do you know if your car had an after market A/C unit installed on it?
