Yeah you're better off with buying a USDM harness... Also, be sure to pick up a OBD2a harness, not 2b..

It will work, but you'll have to run an extra wire for the tach signal since that changed up.

CODDINGTOWN

How do I tell the difference when buying between the 2A vs 2B? A few that say OBD2 on Ebay/Craigslist, just want to make sure I get the correct one.


Thanks for the help. Learning as a go.

I'd check out acuraautomtoiveparts and see what the part #'s are -- usually the ebay people still at least have the OEM label w/the part # on it still.

But adding one extra wire isn't that big of a deal, if you can only find an 98+ harness then just do that.


***Sidenote: I actually have an OBD2b GSR engine harness off my old motor, nothing is cut/modified on it. Let me know if you want it, also still have those ABS sensors if you want those.

CODDINGTOWN

Ok cool. I'll look around for an Obd2a harness, or I'll hit you up for that one.


Been a busy last week or so since I got the motor in. I have been getting a trickle of small parts, and this Sunday I should be able to take care of most everything w/ exception to the harness.

Got a DC header because I needed one w/ the 2.5" outlet, and here are some of the things I've been getting from my local dealer, using AcuraOemParts for PN's to save the local guy time.

ITR engine wiring harness.

Your random plug appears to be the vehicle speed sensor plug. Looking at the shape and pin count that what comes to mind.

CODDINGTOWN

Cool. Thanks!


And no real updates from the weekend except some more parts showing up FedEx, and from the Honda dealer on Friday. An Illness in the family has slowed progress.

CODDINGTOWN

Finally had some time to get stuff done yesterday. Harness, downpipe, exhaust, shift linkage, axles, clutch hose, bled clutch, bled brakes, and a few other small things.


I do need some input/HELP though.

I have a connector that I don't know where they go. One is a 3rd plug where one goes to the Vtec solenoid, and the other looks like it goes to the reverse switch on the bottom of the transmission. just don't know about that last one.

Another connector I have is for the Crank Sensor, that I will have to make the jumper for. (not sure if related to next question)

The other is about it not wanting to turn over. When you turn the key the starter relay clicks, and it has power to the main wire at the starter. But the small (trigger) wire doesn't get power when the relay clicks. Is the an immobilizer or something? Battery is a little low, but should still get power to it. If I jump the connection it will kick the starter. Fuel pump runs too. So it's something between relay and starter.

Should only be 2 plugs on USDM Vtec solenoid. Green capped plug, and a gray 1 wire plug.

The reverse switch runs to the bottom of the transmission. All it does it trun on your reverse lights when in reverse. Nothing other than that. That plug is on the same main loom coming off the harness as the vtec solenoid plugs. That may be your extra plug. I believe it is a 2 wire plug and is gray. I can send you a pic of mine later tonight if you want.

you really just need to get a usdm harness and it should solve your problems.

CODDINGTOWN

Oh sorry.. Have the USDM harness in there now. It is a OBD2B harness though. Using the P73 ECU from the JDM swap I got. So it has the extra wire for that crank sensor.

And yah, quick recap. Fuel pump works, relay clicks under hood, has power on the main wire at the starter, just doesn't have power to small wire at starter.

Other thing I just thought of. Since car came from dismantler, I had no key, so put another ITR ignition into it. Did the 97' have an immobilizer, or is that only on the 00-01'?

John M

pretty sure the immobilizer is in the ecu on usdm. you dont need the crank sensor for the jdm computer if i remember correctly. is your thermostat ground grounded on the tstat housing and the 2 wires with 8mm bolts in the fusebox and not reversed?

CODDINGTOWN

Wire is grounded to T-stat housing, and other two wires are correct in fuse box because the one closest to the middle only goes in one way because of the offset in the eyelet.

Don't worry about the crank position sensor.. jdm ecu isn't looking for it. Immobilizer is on later year ITR's so you can rule that out too.

Have you checked the ignition switch?

CODDINGTOWN

I will have to check that. But would it send signal to starter relay, but not starter?


Thanks for all the help everyone!

CODDINGTOWN

a few more bits of info, and a picture of missing plugs in question. One is for crank sensor. other? And two wires coming from fuse box are in correct place. Just double checked. One has the tab so can only be located in the furthest inner spot.

ECU number is -- 37820-P73-023

Also, the stereo has never turned on since I've had it w/ no ECU/Harness. Just flashes the red light.

Been following this thread. Keep up the good work man. I love when people restore '97 R's. Finding one to restore nowadays is just so rare. Here's my buddy Blake's '97 R restoration thread if you wanna check it out...tucked ABS! http://www.k20a.org/forum/showthread.php?t=72354

Might help to post what color wires the plugs in question are using -- that way you/someone can look it up in the helms.

Have you pushed the button to turn on the radio after you got everything hooked up? Should ask for the radio code when you do.

Black plug looks like the EVAP plug. Is that in the same loom as the injectors? Looks just like an injector clip but its a little bit different.

The gray plug im not too sure on. What color are 2 wires coming out of it and where in the bay does it lay?

DC2-ProdUcTiOnS

Here is a view of that plug and the sensor on my '01 NHBP

CODDINGTOWN

Awesome, thanks! I'm missing that sensor, so need to get it. I have the other one on the back of the manifold that I thought replaced it since a JDM motor. And that plug on the transmission I realized is for the Vtec (CKF?)solenoid that I only have (1) plug on.


So now I just need to figure this no cranking/signal to starter issue. I'll be out of town from tomorrow til sunday, so not much will get done tonight.

DC2-ProdUcTiOnS

iTrader: (2)

not too sure on that being the CKF switch.

The CKF switch is behind the crank pulley. The plug runs along the oil pump. I just did that whole swap with the CKF sensor.

If its on the trans side i would guess its the reverse switch. I'll look lat my reverse switch later and see if the plug is the same as the one you show.

The part number for that sensor is PN # 36162-P73-A11



#3 on the diagram

DC2-ProdUcTiOnS

The CKF sensor is #14 in this picture.

CODDINGTOWN

Sorry, not CKF, but the plug that comes out sideways below the plug on the Vtec solenoid. I have the early one, that only has (1) plug.

And I'll get that solenoid.

Out of curiosity, what does this one do on the back of the manifold?
