I found a 120mph instrument cluster out of a 1993 Cougar XR-7 for my 1991 TBird LX. The thing fits and the plugs fit perfectly, but it doesn't work. The tach, speedo, and everything else doesn't work.

What do I need to do to use it. My original cluster has a speedo, fuel and temp gauge and dummy lights. The XR-7 unit has everything that an SC has except the boost gauge.

Do I need new senders, wiring harness, or will it just not work?

I'd like to know how to swap them also.

I bet TCCoA.com would be a better source of this info, actually ive read about it there before. All SC's came with the "sport" cluster with tach, so there probably wont be much swap info to be had here.

The plugs are identical, but the wires need to be removed and inserted into different locations in the plugs.
