Ok, im swaping in a obd1 B16 into my 96 EX. Im down to the wiring and the obd2 dizzy has one plug and obd1 dizzy has two plugs (one 7 pin and one 2 pin). I am using my ex harness. My question is how do I swap the plugs over? The 7 pin off the obd1 plug has the same wires except for thew black/yellow wire which I know goes over to the 2 pin plug. Theres a dark blue wire though which isnt one the obd2 harness. How do I wire this into my ex harness? I hope I explained it good enough. Everyone on hondaswap.com says I have to get a obd2 si dizzy and that I cant wire the obd1 dizzy to my obd2 harness, but I know i have read somewhere in the past that you can, and I cant see why you couldent anyway?

 

if you hav'nt already done this, remove the pins from the plug on both dizzy's and swap them, you also need to run a few wires for vtec... for better response post ignition questions in the fuel management section, btw, im uncertain if an obd1 and 2 are interchangable, you may need to swap out the sensors and the dizzy harness complete, its a chore, but possible

 

oh yeah.. ok, the wires are.. 7 pin= 2 crank angle, 2 tdc, 2 cylinder position, and the last is a ground, the other plug is pos and neg of coil. im not 100 % because im going by memory and im color blind to boot, but the blue black should be going to the ground on or near water pump?????

 

Hey, thanks for the reply. I figured it out, the wires where a different color on the harness but not one the actual dizzy itself so I swaped them over. Im using the ex harness so I had the vtec plugs already, just lengthened them a bit. I didnt realize this was such a complicated swap! Ill have to post a "how to" on it, because alot of the research I did, did not pull up any clues about the power steering hose issue and other problems I ran into. Anyway, thanks again, ill post pictures of the swap soon, im going to start her up tomarrow! Hope it goes well. Later.
