Well I just put in a b16A and I went to check my codes and I am getting a code 20 Electrical Load detector. I don't really know exactly what that means. I have also put in a sir gauge cluster and the tach isn't working right when I am at idle it shows 0 revs, when I am driving the revs go up but if I put the clutch in the revs drop back down to zero. That might be part of the reason for the cel code. The is also a light on in my cluster that I can't find out what it is for. it looks like a overheating light, it's always on when the ignition is on an when i turn my park lights on it gets brigther and i can controll it with the dimmer switch for brightness. my gauge cluster lights turn on but don't have a dimmer to it. I can't find a wiring diagram for that cluster. My car is a 95 civic dx...could I just have some wires backwards on the cluster? I didn't change any of the wiring, so maybe i have to?
