I have a 91 civic hatch with a b20 swap, I picked it up with a jdm cluster, my EF has cable drive, so there is the first thing I need to tackle because it is missing it i think thats the reason the speed tach dont work. I did a search and found the wiring info, but i'm kinda confuse which is the speed sensor on it, and i am a noob to this honda scene so correct me on the parts im wrong.

Do the two clusters have interchangeable parts, meaning can I take the mph cable drive speed assembly apart and place it in the other housing utilizing the electronic vss in the jdm cluster?

Second question, what is the best way to change from cable drive to electronic vss if its possible with my swap?

Any help would be appreciated, I was unable to find an answer using the search function, but I'm sure I cant be the first to attempt this

 

The crx faq on the top of this forum is where I would start...




And probably finish, all of this has been covered before on this site and numerous others.

 

Did you even search?

FYI I'm working on a proper write up and should be done with it in the next week or so.

I currently have other more pressing items i.e. finals and the 25 hours of Thunderhill.

 

yeah i have searched.
n i am looking foward to seeing your write up so pm me when you have it up please

 

Will do! I'm working on the sub-board when I have time... looks like they're only feeding power... never mind I just figured it out while typing this. I need more sleep!!!!!

I'll try to finish it by next weekend as I need to add a few items to my cabin harness and would like to have that done first.

Just so happens I'm working on the cluster / dash harness out of the car so I can do near simultaneous work. ;-)

 

ok n yeah same here since the last owner must have did the wiring wrong since the speed tach aint working n do you need to have the speed cable in the car cuz if so so i can go get one asap

 

I'm going to recommend you buy a vehicle speed sensor (VSS). I like the idea of it a bit more than running the cable to a modified gauge - I saw that here on HT a week or so ago.

 

well im guessing the jdm cluster i have is running of a vss cuz i dont have the cable but where do i look to see if i have VSS

 

is there a way to find out if the cluster is not working cuz everything works but the speed cluster

 

You know, I don't think we can get away with saying that with the new "backwards" search engine. We used to be able to clearly pull up the search terms VSS as a thread title, now you have to sift through any POST titled VSS.

God it's annoying.

 

Look on the transmission near the firewall under the intake manifold.
(If you need EXACT location then do a search for a picture on the net)
This is where the gear for the cable drive is mounted.
To swap to VSS you replace the gear with the electric VSS and then run a wire to the cluster.

 

thanks for the help bro but i found out i have the electric vss. but the thing is idk if it is the vss in my tranny that aint working or the speed tach in the cluster itself that aint working.

 

My guess is that something is wrong with the wiring.

Make sure you are getting 12V in to the VSS with the ignition on.
Make sure the ground wire on the VSS is really grounded.

You can bench test the VSS by taking it out of the tranny and hooking the 12V directly to battery and running the ground wire direct to ground.
That will make SURE you have the proper voltage.
Hook the 3rd wire (the one that goes to your tach) to a multimeter and look for a 5 volt pulse while you rotate the wheel on the VSS.

 

You should have a 3 pin plug on the top of the VSS sending unit on the trans, you may want to check for ignition and ground with a VOM (meter) at this plug. The 3rd wire is the VSS wire connected to the cluster, this wire is a AC signal and pulses +/- when the vehicle/axles are moving.

ok so which wire
starting from the fire wall is the pwer wire then the middle wire is the signal wire n last close to the engine is the ground wire correct??

 

Got colors?

 

no since the vss i put in came with the plug but no wires so i had to take apart another plug take the pins out n put em into the vss plug

 

Black - ground (outer)
Yellow/Blue - Ignition + (center wire)
Yellow/White - VSS (outer)

Not sure where they sit in reguards to the firewall w/o going out in the cold

Kirk R

 

but let me see wat colors are on the pin

 

well where is a good place to connect the power wire

 

For testing? Straight to + on the battery.
For permanent install you will need to find a switched power wire - meaning a wire that provides 12 volts only when the ingition is on.

 

Use this pic and the colors I gave you to compare

 

ok i will test out the vss first thing tomorrow when im off work cuz im at work right now lol
