Thank you, Dale! But where do those wires go? I'm reading the JDM cluster thread now but hate when a photo tutorial no longer has photos. Grrrr!

 

No resistance measurements yet, i asked what wires should i test, and posted pics of my connectors, cause in some thread said that who erver did it (cant remember who) was not sure about the colors and which plug was it.
I have a 94 cluster with 99 tach and speedometer.
Those wires to the back of the cluster belong to 99 spec cluster, which i am not using. And they go here.
But again , i am not using the 99 cluster.
My 94 cluster is so much different, that those wires dont exist on my 94 cluster.
Thanks

 

Red,

Copy, you are using a 94 USDM cluster with 99 JDM tach & speedometers.

When it comes to reading wires, the Body Electrical Manual is the Bible. Do you have a copy of it?

Look at the Instrument Cluster Circuit, Pg C1-3 (PDF Pg 5). It will tell you many things: connectors, connector shapes (very important for the cluster), wire color codes, and component locations. You can print out the page(s) to take notes on it and trace over lines with colored pencils. That would ensure all wires associated with the speedo board/instrument cluster are checked.

Does that help?
George

 

Thank you sir,.
I dont have a copy, but i can look for it.
Thanks again

 

Red,

Consider a copy of the body electrical manual as a basic tool for any electrical work on the FD. It is like using a 10mm socket or a Phillips screwdriver on the car.

If you have any problems finding a manual then let me know.

Cheers,
George

 

Hmmm, I wonder what that little circuit board is all about! What does it control?

 

I was trying to understand that too, but i have no idea. ts connected there.

 

Red,

Could you slide that small circuit card out and take some photos of it? Maybe close enough at different angles to read part numbers on the comonents?

Cheers,
George

 

 

Red,

Thanks for taking the photos of the board. Could I bother you to take some closer photos or perhaps fill in these blanks?

Cheers,
George

Sure, i can. It might take me sime time,though. I have been super busy, but i will put the most info i can for those components.
Thanks
