Hello I have a 1991 Honda Civic Si that I changed the motor in. I dropped a d15b vtec (OBD1) in it and ever since none of my gauges have worked except my RPM. I am not very worried about most of the gauges, except the temperature gauge. My car seems to be overheating but I am not sure with out my gauge working. Anyone have any ideas how I can fix it or rig something up to monitor my temperatures? Thanks in advance!
