Just wanted to share with all of you that own a CRX. This is my S2000 AP2 cluster swap write-up in my 1991 CRX SI. Hope all of my info helps you out. If you ever wanted to do the S2000 cluster swap in your 1990-1991 CRX. This info should help you out. On getting the AP2 S2000 cluster working in your CRX.

These are the items you will need to make the AP2 S2000 cluster work in a CRX. AP2 cluster, Speedohealer V4 with universal harness, Modifry ECT Module, and a VSS Electronic speed sensor from a 1992-1995 Civic.

I have listed my wiring write-up below. And all the links to websites that, I got my info/stuff from. If you need any help feel free to pm me. I will try my best to answer your questions. Only thing not working on my AP2 cluster is the coolant gauge. I should have that up and running soon. I listed three videos of my AP2 cluster at the end of this post enjoy.
