how can you tell if you have a obd1 distrubitor or obd2. i dont know what i have can someone help. i have a 98 integra would a obd 1 fit it, i know its a stupid question but i have a sloppy situation in my hand with this car it has parts from all kinds of years. 93 block converted to obd2 94 head converted to obd2. i just did a motor swap and put the original b18b engine but it didnt come with the distrupitor so im putting the old one put i want to make sure that its the right one.
