I took my car to the BAR referee station in my area, and would have passed the swap if I had a check engine light....
Since my speedometer doesn't even have a check engine light, I'm guessing the KA24E is OBD0. So if I were to swap in a dual cam speedometer, would I be able to run the diagnostic wires (that I didn't splice into the white dash clip) behind the dash and solder them onto the new speedo harness, and use my single cam harness with a dual cam speedo, or would I be better off just finding a dual cam dash harness, swapping back to the brown dash clip, and running the new harness behind my dash? S13s come to the Pick N Pulls in my area about once or twice a month, so sourcing one wouldn't be too much of a problem for me.
Any input would be helpful, since I can't seem to find anything here or on Google.
