I have an 89 DX hatch that I bought 2 weeks ago. I installed a 91 CRX Si dash and I need to change the wiring so it will work with the 91 cluster. Can someone get me the wiring diagram for the 89 Civic dash gauges. I have a Helms from when I did the motor swap in my 91 CRX but I don't want to buy one for an 89 for such a small part that I need.

 

the wire colors are the same for all CRX's.
The location on the pins is different. So, you need the clips from a 90-91 CRX to get the wire locations correctly.
then just repin the 88 clips like the 91 clips and you are done.
I wired my JDM SiR cluster that way. Even the SiR in japan uses the exact same wire colors, just on different pin locations.
you can get the pins at just about any junk yard in your town.

 

I never even thought of that I guess all I need to do is compare the wiring in my 91 CRX to my 89 DX and then make the changes.

 

I have an 88si... and 90 is when they started making the different gauge clusters right? How difficult would it be to install a new SiR cluster? Or mabye even a ZC one?

 

beware of the yellow w/ red stripe!!! there's three of em

if you run into problems, email me. i have the diagrams at home.

 

hey i was qurious if you had a wiring diagram for the blue clip that plugs into the center of the gauge cluster it has 5 wires. ty

 

there is? oil pressure is yel/red, vss back to the ecu is yel/red, but whats the 3rd one..

 

Thought a quick bump...I was wanting to know what the 3rd yel/red wire did also....

 

since were on the ef8/9 jdm cluster...

ive had one sitting at home just waiting to be installed.
but it didnt come with pigtail, except the green one. are there other similar pigtails that would fit into the plug holes/slots?

 

What is that 5 pin plug for?!

 

I was told that it is for Cruise control. I don't have it so I didn't have to worry about wiring it...
