Whats the difference in looks from the OBD1 prelude single cam and dohc vtec injectors?? If I'm not mistaken.. the single cam is 240cc and dohcvtec is 345, but physically how can you tell them apart? as for obd 2 is 280? I might be wrong.

 

anybody?

 

You have it right, as for telling them apart....no clue!!

 

look at the tips, they are different colors...

345cc obd1's are green (dark green) 280cc are light brown etc.

that and the clips to tell if obd1 or obd2, an obd2 harness has blue inserts whereas obd1 has white..
