i just converted my 91 dx hb to mpfi. i used everything from a 88 crx si. i want to wire the dizzy for the round plug. do i just match the wires up by the colors or what?
example....
white-white
orange-orange
white/blue stripe-white/blue stripe....etc?

exactly man...but the two new wires that are on the si dizzy blue/green blue yellow must go to the new pins in the ecu harness. i think blue green goes to c1 and blue yellow goes to c2. the two wires that were at c1 and c2 also need to be moved, the c1 goes to b10 and c2 goes to b12, make sureyou get all the wiring right, or else it wont run right

Yep, also a few sensor wires you7 need to extend and switch the TPS wires I beleive it was.

ok
i just bought my 2nd dizzy...it just turns over..
gives me a code9
that means that the dizzy i just bought is junk right?

i have been haveing probs with this car....i was just checking to make sure that i wired the dizzy right.
it did run but would not idle right..and loaded up,was running rich. but it threw no codes...so i bought a pr4 and tried that. it ran but threw the code 9...so i searched for anothe dizzy,found one,...but looks like it is junk too.

** not a valid code for V-6 engines

i got that once, but it went away after awhile, my car still ran fine when it was throwing that code too. are you running stock injectors and a pr4..right?
lets run over it again:
---Connect the yellow/black wires from the two DX injector harnesses and run it to the yellow/black wire on the injector resistor box. Connect the yellow wire from the DX injector to the #1 injector (brown wire). Connect the red wire from the DX injector and run it to the #3 injector (blue wire). you have to cut and solder a wire onto the a3 wire at the ecu plug. Connect the A3 wire to the #2 injector (red wire). do the same as the a3 to a7 and aonnect the A7 wire to the #4 injector (yellow wire). Connect the 4 red/black wires from injector resistor box
to each injector.
---cut wires c1 and c2 at the ecu plug and solder wires onto them and run them to the engine bay. c1 goes to the blue green and c2 goes to the blue yellow. run the other end of c1(orange) to the b10 spot and c2 (white) to the b12 spot
then you have to switch the two outside wires on the tps and extend them so they can reach there plugs.

and if you swapped out to the round plug make sure all the wires matched up
