88dx

Is this only for HF/Si's?

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:


Somebody once wrote:

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(P2 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?)
B13----------TO-----------B9 Starter signal
B10----------TO-----------B11 CYP-P(WHAT ITS CYP-P?)
B12----------TO-----------B12 CYP-M(WHAT ITS CYP-M?)
C1-----------TO-----------B15 CKP-P(WHAT ITS CKP-P?)
C2-----------TO-----------B16 CKP-M(WHAT ITS CKP-M?)
? -----------TO-----------D4 Service Check Connector
C6-----------TO-----------D13 ECT sensor
C5-----------TO-----------D15 IAT sensor

heres a working diagram...

someone besides myself deserves credit for this work

im thinking in make my own converssion harness to OBD1 for my EF DOHC ZC. i know need OBD1 dizzy. well what i want to know is what kinda wire it's proper to use for arness. and if anybody has diagram for make conversion.

Ogubudiah if u have same pic but a lil big will appreciate it!
