ok i have been searching and referencing my problems to post in the archives and what i come up with is way off...

im wiring a jdm H22 in a 89 si.
the car had a obd0 b16 in it prior

I used Hasport's conversion guide and there is some things i am just like WTF!!!
maybe you guys can help.?
on the p13 harness...
D10 - ELD signal ?
A19 - intake Air control solenoid?
A17 - IAB solenoid ?
A16 - Alternator control/output signal?
I cannot figure out these wires

ON the pr3 harness, I have these wires left/unused. Do I need them?
Everywhere i have found pinout maps they wires are N/A and they dont match up with anything on the P13 harness
A6- grn/blk wire
C9 - red/white - P.S. pressure ?
B2 - Blue wire ?
B17 - ignitor - white wire ?

in the archives... i found some links/posts saying for the a16 alt C that it goes with b5 on pr3.
but looking at this hasport conversion guide, B5 is vtec oil pressure, WTF?
right now i have B14(obd0) - D9(obd1)

the only wires I have left from the Hasport guide is what i listed above for the pr3 stuff that i can't figure out.... (a6, c9, b2, b17)
Is any of this stuff different with me using a Jdm p13.

any help is appreciated, thanks guys

 

IM/PM the member YumVTEC. He just got done doing his for a B17 in his EF with OBD1

 

thanks, anyone esle?

ELD is not used for obd0 pr3 ecu or wiring, you will need to add the ELD wire to your engine harness and run it to the ECU. I don't show A19 on this list that I used which is for an OBD1 P28: http://www.boosted.org/obd0_to_1.php - however, there is IAC at A9 (OBD1 side). ALT C is not used on the obd0 pr3 ECU or wiring, you will need run it from your obd1 p13 ecu plugs to the engine bay (or wherever it is supposed to go). IAB (secondary runners on dual-stage intake manifold, only on h22's and b18c1's) is also not to be found for obd0 pr3 ecu or wiring since the b16a's have single stage intake manifolds. you have to run this wire to the engine bay to the IAB sensor/solenoid on your h22 intake manifold (unless you bought a single stage manifold).

A6 (OBD0 side) is for the EVAP purge control solenoid. C9 (OBD0 side) is unused unless you have power steering in your car. B2 (OBD0 side) I don't see anywhere on the table in the link I provided above, nor is it found here: http://tech2.hybridgarage.com/...pr3_a - B17 I couldn't find on the obd0 --&gt; obd1 conversion table, sorry.

ALT C doesn't exist for the PR3, you won't be able to run from obd0 pin to obd1 pin on this one, you'll have to run from the OBD1 pin to the engine bay as mentioned above.

 

Thanks alot.
now im stuck with this...
I dont know whyt i listed A6 above.. its supposed to be a14 which I have no idea what it goes too? Thats the only wire i have unused on the pr3 harness
And does anyone know where the Alt C wire needs to be attached inside the Engine harness i.e. (on the Alternator somewhere, which wire is it?&gt

Or anyone know what color wire the ALT C wire is at the ECU? from the Pr3/stock crx side?

Also...
Now after all this wiring... the climate control lights or on all the time and when i try to turn on the headlights everything turns off....
bullshit, i didn't even touch the light wiring..
any ideas?

This link says that A14 is for fuel pump control. Find a corresponding wire on the obd1 side and you're set.

As I mentioned above there is no ALT C wire on the PR3/CRX side. You have to run it from your obd1 ecu plugs directly through the firewall, into the engine bay and connect it up however it is supposed to be connected at your h22 alternator.

No clue on your climate control wiring. something isn't grounded right probably.

 

Ok everything is good to go except...

ON the pr3 there is 2 fuel pump relay wires...
A12 and A14
I have A12 to A7 on the p13 stuff
but nowhere have i found where A14 goes...
the p13 only has one fuel pump relay wire

Do i need to wire it directly to the fuel pump relay..
if so any know which wire it might happen to be on the fuel pump relay?
Can i splice them together?

thanks

just don't wire it up and see if you throw any codes. if you do throw codes, then worry about that wire at *THAT* time.

only thing is that its not pulsing the injectors and turning on the fuel pump..
So it wont throw any codes because it wont start

 

it should throw codes without needing the motor to run first. if it doesn't maybe the ECU isn't getting power. does the CEL come on for a brief second when you turn the key on?

also, don't you need to run an injector resistor box if you're obd1 h22?

yea the CEL comes on, I think it stays on too......
The car aleady has an injector resistor box. Didn't think i needed to convert to the new one...

How in hell am i supposed to check codes on this thing?

 

umm, you take D4 on the obd1 side and you connect it to a ground and your CEL will flash the code out. welcome to obd1.

thanks, i was searching and hearing people saying i needed to put a toggle switch on two wires...
thanks

 

However you want to do it as long as you ground the pin to get the code. I used a small switch for it too.

 

switch does make it easier, so that you don't have to physically keep the wire touching a ground while you check your codes.
