im right in the process of doing the mpfi -dpfi swap. injectors are finished now im depinning the mpfi dizzy plug to put on the dpfi harness... well accordoing to Ben O's write up there is a blue/green and blue/yellow wires that you need to keep from the mpfi harness... those wires are for the crank position sensor (c1/c2 on ECU). well there is only a blue/yellow wire. No blue/green... there is a fat blue and a fat green that is not on the DPFI harness. also, the wire colors are no where NEAR the same on the from the mpfi to the dpfi.

so what i need to is where do the wires from the DPFI go to make it correct on the MPFI? there are also two black/yellow wires and two yellow/black wires (one bigger gage than the other) on the DPFI harness. Ben also says there are two Whites on the dpfi that you need to pay attention to... there is only one

 

anyone have any input on this??

 

also, i noticed that a lot of other write ups say that the dpfi dizzy plug is square... the one that came off of my car (91 dx) is circle... same exact plug as the one on the mpfi harness... just the plug wires are is different spots and different colors

 

can you take a picture of what you have?

 

X2 that doesn't sound right.

 

sounds like someone ghetto-rigged your harness or maybe had it mpfi at one time an did wat they had to do to make it run back dual point wit the parts they had, the dualpoint wires and mpfi wires shood be exactly the same colors except for the xtra 2 bl/gr, bl/yel wires

 

What he said

 

the dude that had it before me ghetto rigged it. but i got it all figured out finally
