'72 Delco radio installation question

[Stan B.]

I am in the process of placing an original Delco radio inside my '72. Under the dash I located the black, yellow, and gray power wires that connect to the radio's black female power plug (located on the side of the radio); however, they have been removed from their male power plug and are simply dangling under the dash. I located a male connector and installed spade connectors on the wires but haven't a clue as to where I should insert them or in what order I should insert them on the male connector. Any suggestions? Thanks -- Stan

Stan, the radio terminals on the L.H. (drivers side), rear is radio light, (towards front of car) blue or gray, center terminal BLACK. (ground), last, YELLOW, (ign, power source) (towards rear of car). Hope this helps. Steve
