I'm by no means a radio install expert but it appears to me the plug you are holding is for the gauge pods not the radio
That is the harmonica connector that plugs into the circuit board for the gauges. Since the OP is installing a double-DIN head unit, this connector will probably not get reused.
Most new radio's of decks you need to identify the wires on all connector, cutoff and install matching wires from new unit. You need to use splicing sleeves and a tool to do this. Don't wrap together and use tape or marr connectors or trailer connectors. It is best to stagger the connectors by their length to finish with a neat job and not have a huge bundle that stops radio from going in.
that is the connector for the gauges. You likely can buy an adapter for the radio harness plug from your local car stereo store though, or if not, likely from Crutchfield.com. DON'T go hacking off the original radio plug unless you have to. I've gotten adapters for every car I've put a stereo in and didn't have to cut one single factory wire. It makes for a much neater installation.
The big challenge will be getting that double-DIN head unit, at 6.5 inches deep, installed where the motorized screen dies not crash into the A/C controls. By my estimation, the face of the head unit will have to be 2 to 3 inches rearward in order to clear the A/C duct on the dash.

Thanks do you think Crutchfield.com they have an adapter?
There could be 2 or 3 connectors on your 77.
MONO: If it was a mono radio there will be a power plug with yellow, gray and a black wire. One speaker wire connector plug to radio had 4 wires.
STEREO: Same power plug as configuration above. There will be a separate plug for each left and right speaker. Each plug will have 2 wires.
This is the wiring for my original 77 AM/FM 8 track stereo. Top plug is the power plug.
