1978 Buick LeSabre Radio Help

[MetallicAH20]

Hi

My name is Will and I own a 1978 Buick LeSabre Custom 4 Door. The previous owner of the car put in a crappy 80's tape deck in place of the stock AM/FM radio. When I bought the car it car came with the original radio but I am not sure if I am missing a connector and if the wires that are in the stock connectors are correct. What I am asking for is a wiring diagram so I can put everything back to stock. On the radio there are two connectors, one is long and rectangular and has a black wire and a blue wire in it. The second has a yellow wire and a grey wire in it and the connector has the shape of a boxy triangle. It looks as though I am missing a small rectangular connecter but I am not sure. The location for where the antenna plugs in is on the side of the radio.

The radio is a

AC Delco
Service No: 52BFPK1
Serial No: 1015004
Model No: 9343492

The car is a stated above a 1978 Buick LeSabre Custom 4 Door
Any and all help would be greatly appreciated.
