So i just got done swapping in a b16a into my 91 dx crx. Everything works fine, car runs good. But the speedo doesn't work. It seems to all be hooked up correctly. I was just wondering if i needed to change it out. Because im using the one that i used with my d16 motor. I didn't know if there was a difference in the. Or maybe you guys know how to troubleshoot it. Thanks in advanced.
