I hope I posted this in the correct place. I'm doing a b18 turbo build in my Crx and the wiring was hacked. I went the lazy/clean route of ordering a rywire tucked harness and rywire race chassis harness. Now Im in the process of trying to find what each wire does on the back of my cluster in order to get working what I need. I found every wire for the two big plugs on the back of the cluster but the blue one in the middle I have no idea what it is for. I normally don't post questions because there are a million threads on just about anything I need to know. But the couple threads I have seen for this little blue plug no one can give a definite answer on what the five wires are for. Any info on this would be great. Thank you
