Hello

Been Trying to swap the Gauge Cluster from a 91 Roadmaster to my 91 Caprice. I didn't think it be that hard, but when I removed my guages. I noticed a difference the caprice cluster has one connector. While the Buick has two. Is this swap even possible? Do I just need to buy another harness?
Any advice?

Do you have a donar car that you are doing these swaps with? I would just take the harness from that.

Nope got the cluster off of ebay.
