i just did a obd0 to obd1 conversion on my 88 hf rex with a b17(gsr) and when i had to extend the coolant temp sensor wires, for some reason i put the positive wire on the ground when i spliced. it threw a cel #6 ECT- Coolant temp. i fixed the wiring, the temp sensor reads but throws a CEL... do i have a relay out or a messed up sensor?
everything else on the obd1 swap came out alright except for the vtec spool valve solenoid CEL 21 because i use to run vtec via piggy back.

someone told me to check my main relay but idk if its good or not, or if it even has anything to do with my coolant temp sensor throwing the cel.
