Heres the deal...I have a 1989 Honda civic Wagovan (D15B2), and a 1993 Del Sol Si (D16Z6). The del Slo is beyond repair, and the D15 is Blown, so i ws thinking D16Z6 swap in.
I have a jumper between the ecu (p28 obd1) and the main harness. so now i haver to do DPFI to MPFI. But what is giving me real fits is the jumper between the OBD1 Dizzy and the OBD0 engine harness. What i dont have is the color code combination between plugs ie. Blu/yellow wire goes into Blue wire etc etc can you guys help me out here?

The plugs i have are an OBD1 dizzy plug male and female and
OBD0 5 wire dizzy plugs male and female (everywhere i look says it should have 7 wires but mine only has 5).......THATS MY ISSUE.........HELP

 

Just de-pin the pins from the 7-pin obd0 plug and put them into the obd1 female plug. all the wire colors should be the same besides the big white wire on the obd0 side and the yellow/green wire on the obd1 side. obviously these to go together. and for the 2 pin connector, just cut the obd0 connector off and solder the obd1 on. same wire colors.

 

Just read where you said you only have 5. how many pins are in the 0bd0 7 pin connector?

 

I dont have and cant find an obd0 7 pin dizzy connector. all of the dizzy plug i have found r 5 pin.

 

If you only have 5 pins it's because you haven't done an mpfi swap yet... Those are wires you run during the mpfi swap

 

Your absolutely right i have not done the swap yet..Mostly because i dont know how to do it.Yes i have found instructions galore on how to do it, but to be honest the instructions scare me to death, what if i mis wire something and fry my ecu?

this is my first Honda swap. only my second honda period. My first one came factory mpfi (91 si hatch) I honestly odnt know much at all about hondas let alone sitting down and tearing my wire harness apart and adding wires to it... i guess i am going to have to though IA is in 2 weeks

Well i bought my jumper harness from Boomslang but it is a OBD0 - OBD1 only not the DPFI to MPFI jumper.... and now i am out of money (i would lvoe to be able to buy a PnP harness but........
