I don’t even know where to start…. Ok and yes I did search but all other forums don’t have the answer I’m looking for.


1st car is a 2000 ITR that was super charge and now I want it completely stock because its a clean title low miles ITR and I want to keep it that way.

2nd car is a 1998 ITR with a rebuilt engine top to bottom and where the 2000 ITR supercharger is going to be installed.

So I swap the complete Jackson super charger into the 98 including the extended 2000 ITR engine harness into the 1998 everything plug in. since the 2000 ITR was using a p06 Ecu chip with hondata sc300 and it was tune already I swap it over to the 1998. I went and bought a step down harness for a obd2a into a obd 1 ecu everything plug and play.
So I started the car today car turn over no check engine light. But my only problem now is that my RPM don’t work ! I don’t know if the speed works because I’m waiting for some suspension parts to come in. But for now the RPM’s don’t work and I cant figure it out.
When I did a research between the differences in the obd2a and obd2b engine harness I didn’t find anything only thing was the plugs into the ecu. And that the 00-01 had immobilizer on the ecu So my question is do I have to re weird any of the speedometer cables so it can work correctly? Or what should I check to see if there something not install correctly?


I forgot to mention... when i first try to start the car it wouldnt crank over the gauges went crazy and made like a buzz noise and the started just click. So i went and clean out all the ground holes to bare metal and try again and the car started right away. so i know the ground wasnt good because the engine was repainted. can it be it cause the guage cluster to go bad?

 

Since your "engine was repainted", check, scrape away the new paint or clean the grounding surface where the long ground screw of the VSS connect to. The other two screws is to hold the VSS in place. Make sure you clean/brush the long ground screw before you screw it back in. While you in there, clean all the grounding points.

If this doesn't works, you might need to swap out the underdash wiring for a 2000 ITR one and swap out the cluster's green circuit film for a 2000 one. GL my friend.

 

yeah I did that already and the engine started up but the rpm's is the only thing not working.. I put the car in 1st gear and the speed works but not the rpms

Check the fuses if you havnt already. My 97 civic blew the alt./vss fuse once and the speedo worked but the rpm gauge didnt.

 

hmmm going to give it a try tomorrow..

 

very simple, theres a blue wire plugged off and tapped on the driver side strut mount. that has rpm signal. wire however you want though

 

so i check the fuse and nothing still the same proble

 

does any one know of a good shop i can take my car in the CT or NY area? where i dont have to live the car over night i dont mind been there all day waiting for the car to get fix.

 

Take a look at this http://www.htarchive.com/showthread.php?t=2538296 . That looks to be the simplist thing to do in ur situation.

 

As stated, run a wire from the blue wire on teh shock tower to the rpm signal wire on the back of the cluster. If it works you have a electrical issue somewhere, and if it doesnt work then you need todo more research.


Good luck.

 

this is one thing I hate electrical problems i thought it was all going to be plug and play and thats it..

 

I've been here before and done it. You need to tap into the blue wire on the driver side shock tower, run that wire to the blue wire on the distributor. If you took the harness from the 2000 it does not have a blue wire on the harness and you will need to run it. I added the pin to the 2000 ITR harness @ the distributor right next to the big black wire since it didn't have it.

I'm running a 2000 ITR harness in my 97 ITR and had to do this to make it work. If you still have further issues let me know I can snap of pictures of what I did.

 

thanks for the help just sent you a PM

 

^^^^thats what I say LOL
