kinda....it will only work if you have done a MPFI swap to a DX/LX/std...which it should be anyway... the DPFI plug is only like 6 pins (i think) so you would need to swap to a different plug for MPFI or OBD1 setup....


so do a MPFI swap then this should work for you... :-*

DPFI is a 5 pin square plug... with no TDC or CYP wires.. the MPFI plug is a 7 pin round plug that includes those two wires.

Damn, this thread is very informative. I just printed out like 30 pages of info and pinout diagrams.

I would like to know where to get harness pins as well. There has to be an electronics site that sells these. http://partsexpress.com/ maybe? I'm going to be adding quite a few wires. The OBD-0 pins and OBD-1 pins are not interchangeable, are they? That would be too easy.

I have an 89 dx shell that I'm putting a Z6 and my turbo kit into. I'm planning on doing a dpfi obd0 ---> mpfi obd1 swap, with Uber for fuel management/vtec.

I have the complete DX harness. I have the complete Z6 with all sensors, dizzy, 02, engine subharness. I was planning on using the Z6 engine harness unmodified, except running resistors in line to the injectors so I can use my DSM 450s. I was just going to modify the DX harness that runs from the ECU to the bigass plug in the engine bay.

I still need a obd-1 ecu, and assted plugs. Are the plugs from any 92-95 the same? I can use any OBD-1 ecu, correct? (PR4/P05/P06/p75) Just chip it? I'm heading to the yard, and want to make sure I get the right stuff. There are only a couple of EGs in there.


Sorry for the newbie questions.

I have this problem: I have a TD60U OBD1 dizzy from 92-95 prelude. I'd like to make a coversion harness from OBD1 distributor to OBD0 Si engine harness.

Here are my colors:
http://www2.arnes.si/~mjereb2/WIREcolors.JPG

Somebody once wrote:


First you have 7 wires to use. Left side is OBD-0, right side is obd-1/2. The colors give will be the factory Civic wire colors.


OBD-0 (ECU Pin) OBD-1 (ECU pin)

Wht (B12) ~ Blu/Yel (B16)
Org (B10) ~ Blu/Grn (B15)

Wht/Blue (C4) ~ Wht/Blu (B14)
Org/Blu (C3) ~ Org/Blu (B13)

Blu/Yel (C2) ~ Wht (B12)
Blu/Grn (C1) ~ Org (B11)

Wht(slightly larger, ignitor wire) ~ Goes to same wire on Dizzy side, the solo wire by itsellf
There is listed blue\green (B15) wire under OBD1. As you can see on the pic there is no wire colored like this on my dizzy. But i have green\yellow wire which is no tlisted there... now i'm confused. Do other wires match those on that list?
Any idea?

Im converting my Dual Point(PM5) to Multipoint(P28) and i have some questions in some pins locations from the PM5 ecu, anyone can help?

Heres the pins i need, tell me if are correct (the left ones).

PM5 P28 Function
A11----------TO-----------A9 IAC Valve
B15----------TO-----------A21 ICM
A13----------TO-----------A25 and splice with B1? Main relay
A15----------TO-----------B1 and splice with A25? IGP2(WHAT ITS IGP?)
