Hey guys. I swapped in a 98 b18c1 engine into my 98 Civic EX Coupe. Bought a new obd2 b18c1 distributor from ebay. Used the oem Civic EX wiring harness and plugged the distributor straight to it. Using a chipped obd1 P72 with a conversion harness. Getting Code 9. Anyone have any input on what could be wrong? Please let me know what you think. Thanks!

Update: The ebay distributor plug that gets connected had pins that were not pushed in all the way. I simply pushed them back in and plugged into wiring harness and the code went away.
