i dropped a b20vtec with a b16a head into my 00 civic ex running an obd2 setup. bought a brand new obd2 distributor since the old b16a distributor was obd1. the obd2 distributor plug is fatter and it will not plug into the stock 00 civic ex harness which has a skinnier female plug. can i please get some help on this and find out how i can hook the two up without messing anything up??
