EDIT: I forgot to add this to the diagram I drew when you connect the positive wires for the injectors to a15 you do not cut it you splice in to it by stripping back some insolation on the wire.. and also when doing the mpfi swap you must move the 2 outer wires on the throttle position sensor plug!!

Re: diy dpfi-mpfi swap made easy!!!
Yes that's one of the reasons I made this I know I'm new to this site but it gets old seeing a new post like every other day saying need help with my mpfi swap. and seeing the mess people make of there wiring and hack jobs. its really simple to do if you have a decent right up that explanes it and shows it how it is. I mean some one who never did mpfi swap can understand this right up its mad that simple. so enjoy people hope this helps some people out in the future!!!! Maybe it could be a sticky if the mods like it enough and think it will benefit a lot of people on hear? But I won't get my hopes up lol

For those not fortunate enough to find the Round SI Dizzy plug, you can also use the stock DPFI dizzy plug and use the green 2 plug from a 88-89 integra. That way you can run the C1/C2 wires separately from the square plug. Ill have to snap a pic of my Set up to clarify.

Nice.
I was reading about this for a while and didn't quite understand it.
Remember, you can re-use the injector wires from the dpfi harness... that way you don't have to run so many wires...

Re: diy dpfi-mpfi swap made easy!!!
awesome write up, only thing I think you should change is the injector numbers to match the normal cylinder numbers, so #1 would be closest to the timing belt and #4 would be closest to the dizzy. it would just save some confusion.
