oh ok....well the only experience i have with obd2b plugs are the f20B and my 99 LX civic.

I'm glad you guys know what you're doing. Cause I sure as hell don't lol.

JDogg

pretend like ur 3 again, match the colors

NJcoupe

You match the colors; and add a wire off the ICM for the tach signal I had to do this when doing a 99 D16Y8 swap into a 98 HB.

thehatchninja

yeah, same with the F20B, except ALL the wires are different colors, but I'm pretty sure I got it figured out.

This thread is a good resource, maybe it should be added to the FAQ somewhere.

so you're saying to just splice into the ICM wire on the dizzy and my tach will respond to that?

Bense

All right cheesedicks, looks like i'm going to have to try to figure this **** out:

notes from thehatchninja:




when i get home from this godforsaken job, I'm going to have to dig through some wiring schematics for obd1 civic and obd2 civic and obd2 lude.

Bense your my hero buddy, keep helping me with good info

Bense

I spoke with blundar tonight and he was saying something about getting the rpm signal from the coil ground. I've looked in the dizzy and found a white wire with a dark blue line on it that goes from the ICM to the coil, But there's no external lead to it. I'm thinking that if we tap into this wire, we'll get our RPM signal.

Once we get this signal, does it go to the ecu and then to the tach? Where does the ECU get it's signal from?

Black wire with yellow line, I believe I tried that thanks to thehatchninja.
White wire with dark blue line is what I suspect it to be, but I think we'll have to splice into that wire and get our signal.

I'm trying to download some 98-02 F23 accord manuals but I can only find one and it's not finished downloading.


I got some pictures though lemme load them to photobucket

Bense

wires leading from ICM to Coil: (black/yellowstripe, white/navy stripe)


plug

HeikDiesel

Whats the point in the tach signal again? Does your tach in car not work?

Bense

okay I got that service manual downloaded, it has the wiring diagrams for the accord type R h22a7. Here's the dizzy wiring for this engine, which I suspect will be the same as the F20B



H22A7 Dizzy Exploded



I'm still extracting some more info so hold your horses.

Bense

Here's the wiring diagram for the 98-01 EDM accord gauge cluster. Blue wire, again.

You see that distributor plug with some late OBD2B 00-01 Civic/Integra, the blue wire coming off the ignitor has been omitted, and I ASSume the ECU provides tach feed to the cluster in those cars.

See the fourth unconnected blade coming off the ignitor? That's where the missing blue wire hooks to, homeslice. Slide a blade connector onto that and it's on like Donkey Kong.

My only speculation of that is that brax90si has the f20b as well, and he tried that

Blundar was saying to get the signal from the coil's ground, which is the black and yellow wire, but I believe we tried that and got nothing.

Joseph Davis

The tach feed is a synthesized output from the ignitor itself, it should work.

I'd check to see if that particular ignitor had a different OEM part number than all of the other Honduh ignitors. If it does, try an earlier ignitor. Or since you probably have D-swill laying about just go ahead and try and earlier ignitor.

HeikDiesel

I must be retarded cuz Im lost. Am I gonna run into this problem when doing my f20b too? Is the problem just you simply cant find the tach output?

Bense

Oh yeah, i forgot to reply to what the fix was, run the tach signal from the negative terminal on the coil

atlplayer4life90

ok im lost as well i have a obd1 h22 going into a obd2b civic and i have the obd1 dist. does someone have simple rewire or can i just buy a dist. that would plug right in thanks

UrVtecIsLoud

im doing the F2b swap into an eg can't i just use an obd1 jdm dizzy? instead doing all of this confusing wiring.

jr_deleon

iTrader: (1)

if you use the h22a jdm obd1 yes you can

if you got one, use it

but if spending $170 is easier than reading a page for about 20 minutes, then go ahead.

O i got one, for 40 bucks.

I'm doing f20b swap in 1997 Honda Accord right now.

The F22b1 Accord OBD2a Distributor has 5 wires and is internal coil

The F20b SiR-T distributor has 8 wires and is internal coil

I need to run 4 wires from my crankshaft sensor plug (CKP and TDC) into the plug that plugs into the F20b distributor right?

This is really confusing me. None of the pictures you guys posted are good anymore.

PSPEC

This diagram for H22a7 is the same as for 97+ USDM prelude. This distributor does not have CKP and TDC inside the distributor. They must be on the oil pump in the Accord Type R.

F20B has TDC and CKP inside the distributor, not on the oil pump
