I have a 97 civic DX with a 99 usdm b18b. I did a obd2 to obd1 conversion using the skunk2 harness. I had a check engine light for coolant temp sensor (my moron friend put the wrong plug on it) The car was fine when I had the cel aside from low idle when cold and high idle when warm but now that I plugged the right plug in and eliminated the cel my headlights dim when I push in the throttle unless I'm above 4000 rpm's, they also dim at idle but if I rev past 4000 they will brighten back up. I've tested my alternator and battery and both are functioning properly. I have heard some other people having similar problems when using conversion harnesses I was wondering if anyone else had this problem or if they knew how to fix it.
