Retrofitting 2000 radio into a 98

[Pontiac47111]

I have a 98 TS and I aquired a "WB Package complet with radio and all trim and wiring. I have a non RDS radio with the 21 pin main and 9 pin aux connector. The new radio has the 24 pin main and 12 pin aux plug installed. On the harness it is missing the radio plug from the donor vehicle.

I just dropped the van around a 2004 3.4L engine and planned to update the intereior a little bit. Is it possible to make this work?
