I tried to install the Discontinued Rev/speed meter i picked up at the Apexi garage sale for like $50 in my 2001 Base lude but the wiring diagram and all were totally different. The problem is the manual says the ECU DIAGRAM i should refer to is H3. But when i get down to my ECU it doesn't look nothing like H3. It looks just like H7 - 32P (gap) 31P 16P. The H7 is for civics with B16a or D15b year 95.9~. I tried checking out the apexi-usa website and look at the wiring diagram for the NEWER rev/speed meter which might show which diagram and all i should be using for the 01 Lude but it froze my computer . I'm assuming the older manuals (one i got) isn't updated to 01 vehicles. Could someone look at the Apexi-Usa.com - Documentation - RSM meter wiring diagram and tell me if they see anything that might help me out??
