Icon1 OBD1 <-> OBD2 (motor/distributor swapping)

okay so this last jdm swap i did for euddys was an obd2 lude w/ obd1 jdm h22 motor.
now the obd1 jdm motor comes w/ an internal coil distributor..(which are garbage) so i put an h23 obd1 distributor on instead to make it external coil.
the issue lies w/ the crank position sensor and the top dead center sensors which on an obd2 prelude are found bolted to the oil pump down by the crank gear and is not found on the oil pump of the obd1 jdm h22a motor. alot of people swap oil pumps...but, what if the last motor spun a rod or crapped out... do you really want to trust that on the new motor??? or do you feel like buying a brand new honda oil pump? if you do thats fine but i have a quick fix for all of this.

you install the h23 obd1 distributor where the h22a jdm distributor went and plug in the two wire (blue and black/yellow wire) plug because those are always the same. now the other plug an 8 wire plug has to be rewired.

hopefully your h22a jdm motor came w/ a hacked up engine harness. w/ the 8pin plug sometimes 7 pin plug already on it. cut that off and try to get as much wire as possible. im talking almost to the very end, this wire are insulated and ground shielded which is helpful. then on your old h22a4 obd2 motor cut the 4 wire plug coming from the tbelt cover from the crank position and tdc sensors. your now going to splice these to plugs together.


ckp OBD2 harness grey plug--------------------------to the obd1 distributor plug 8 wire plug
red --------------------------------------------------------------white/blue top dead center senor TDC "M"
green----------------------------------------------------------- orange/blue top dead conter sensor TDC "P"
white------------------------------------------------------------white Crank angle sensor CYP "M"
blue-------------------------------------------------------------blue/green Crank position sensor "P"


obd2 engine harness side at distributor to obd1 distributor plug 8 wire plug
black --------------------------------------------------------------blue/yellow crank position ckp "M"
yellow--------------------------------------------------------------orange Crank angle sensor cyp
yellow/green------------------------------------------------------yellow/green ignition control module
thicker green(found right next to yellow/green)------------------------green ignition control module

now the car can start LOL. hope this helps.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

hahahahah this is EXACTLYYYY what i needed to do last year to get the OBD2 F22 to run in my 95, but then i had to convert the motor BACK to OBD1 once i boosted it again.

took me like a straight day to figure out all the wiring and sensors and comprehending which sensors the ECU will be seeing, etc etc. cuz electrical is by far my least favorite to do.

can you break this down a little bit more for me sir, my question lies mostly in your second wiring paragraph, the yellow,yellow,yellow/green and thick green wires that go to black yellow yellow and green wires,
IN obd2 dizzy .....to........??
im a little lost

next ?
although im not in front of the car right now, i can remember there being a pink wire coming off the sensor(s) from the oil pickup area, or for short as blaze was explaning, with the h23 harnes on the h22, the 4 pin connector, has a pink wire.
again its obd2 h23 harness, how/if may this change anything?

Re: OBD1 <-> OBD2 (motor/distributor swapping)

sorry should have made it clearer. not pink its red trust me ..prolly faded over time. its not going to change anything... those wires are supposed to be wired in to read that the motor is spinning .... this tells top dead and crank position for the spark to be produced in the correct sequence. sorry i didn't make this clearer... i just tried to edit it.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

hopefully this will end any confusion.

i am however a little confused on what connector end to cut of which harness
not so much as not understanding what end to cut, but more along the lines of getting a better picture-schematic
of what needs to be done exactly, before cutting the first wire....
reading is all good, but im a very visual learner as im shure many out there are, we love us some pictures.
feel free to bastardize my schematic in any way nessisary to explain............ more better :)
thanks in every way-
dave

Re: OBD1 <-> OBD2 (motor/distributor swapping)

no sir, thank you you are truly an eletrical mastermind.
now let me attempt to understand the second half of this, as seen below.

moreover i guess what im asking from the pic below, is do i like you mentioned take the jdm h22 harness find the dist. plug and cut it off with as much wire as possible, and then plug the connector into the obd1 h23 dizzy. then i have a h23 obd1 dizzy pluged into a jdm h22 dizzy connector with 7-8 pigtails coming off it.

assuming thats right-
then i take the x x x x 4 wires off the jdm connector and splice them into the wires that WERE once conected to the oil pump sensors.

then (THE BIG ?) is the other 4 wires coming off the jdm h22 harnes need to be spliced into the old oem h23 obd2 harnes that was connected to the obd2 h23 dizzy before the swap. that conection, to me means cut the oem obd2 h23 harness dizzy connector, and splice togther as seen above?
let me know i would be glad to make a final schematic clarifying everything.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

ok so we got the obd1 dizzy.
this one is a re-manned autozone special.
again i stress its re-maned and i have one small problem.
it has the:
White w blue
Orange w blue
White
Blue

Yellow w green
Green
BUT instead of solid black and solid yellow, the final two wires is a
*Solid Orange
*Blue w yellow

the solid orange apears to be a slightly fatter wire, which i am going to ASSUME i will be substituting for my black wire? (or lack of)
leaving the last wire obvious....

Re: OBD1 <-> OBD2 (motor/distributor swapping)

could it be that the wires i need to be looking for in the above mentioned
LEFT side are the wires that come of the OEM jdm h22a harness?
that needs to plug into the obd1 dizzy?

Re: OBD1 <-> OBD2 (motor/distributor swapping)

well she fired right up!
i had to go back and make one modifiction to my first schematic but here it is
simplified.
chart one actual wiring diagram
chart 2 harness end to end
although im using every componet bustr described above in the tutorial, there were still wire color descrepencys but there is an easy way to nagivate through it.
i will post up pics later.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

if i do it this way instead of changing out the oil pump, do i still need to swap out the oil pan and baffle?

also, are all of the connectors on the obd2 harness being used on the jdm h22a? any other issues that may come up? so all i need to do is this modification to the wiring and it's a simple engine drop in with no other changes? correct me if im wrong. thank you and enjoy your weekend.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

NO NEED TO CHANGE PUMP for this to work. it is all wiring for the distributor to work. there are more things you have to do to get the entire swap to work properly but this is the part that isn't really posted up so i figured i would post it.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

This is the schematics that I came up with and later fixed by someone who bought a car with the conversion already done. My original schematics had two wires swapped and now is the correct order

The distributor conversion wiring is as follows:

* OBDII -----------> OBDI--------> function

* Black...............Blue/Yellow........CKP M
* Red................White/Blue..........TDC M
* White.................WHITE............CYP M
* Blue.............Blue/Green..........CKP P
* Green............Orange/Blue...........TDC P
* Yellow...............Orange..............CYP P
* Yellow/Green.....Yellow/Green..........ICM
* Green...............Green..............ICM

what distributor are you using? you need an h23 obd1 distributor.

Re: OBD1 <-> OBD2 (motor/distributor swapping)

hey guys, i'm doing this conversion right now. i just wanted to know. i'm getting CONFLICTING info online from HT and from other sites such as phearable and ffsquad trying to wire this dizzy up correctly.

For some reason my cars throwing a Code 15 (ignition output signal) and i can't figure out why. i wired up to what you guys are saying and thats the only code i throw. if i wire it up to any other sites i throw a different code etc... any help guys?

sorry to bump a old thread!

sounds like you confused your green wire w/ something else. green wire on the h23 distributor is ignition output.

does the green wire coming out of the dizzy go to the LIME GREEN wire on the obd2 harness?

also i'm running the h22 obd1 dizzy, but it should be same as the obd1 h23 dizzy correct?

Re: OBD1 <-> OBD2 (motor/distributor swapping)

okay the ignition output signal is the green wire coming out of the distributor. on your h22a4 obd2 stock engine harness the plug that usually goes down to the crank position sensor has a green wire on it also... but that one goes to the orange/blue wire at the h23 distributor. the green wire at the h23 distributor goes to the other green wire on the h22a4 obd2 engine harness were the old h22a4 distributor plugged into.
