First question is about the O2 sensors. I know the b16 came with 2 sensors right at the front of the header, but the dc header im using only has one bung for one sensor, can I splice the two sensor wires together and just extend it to reach the hole in the dc header? Second is about the speedo cable. My motor came with an electronic speedo unit connnected to the tranny but the crx only has the cable for the speedo. I took the unit off the new motor and there is the hole in which the cable plugs into, but there is nowhere to hold it in place (the stock motor had the clip to hold it) any ideas? thanks in advance for any replies
