on my 1990 crx dx, there are only 2 plugs on the passenger side engine compartment. The big round one and the L shaped plug. But on the b16, there are three plugs? What the deal with that? Is that something that was added to the wiring harness for the swap? I was going through alot of the picture posted here and some have three hooked up for the b16 swap and some only have 2. Can someone tell me what to do??

 

damn you got a long way to go........SEARCH mpfi swap and you'll find out why the plugs are different. you gotta use your DX harness and extend some wires, an run some extras for vtec, knock and the mpfi dizzy. SEARCH, SEARCH, SEARCH!!!!!!!!!!!!!!!
