So I have been looking around and I'm getting confused. I just bought a 99 si gauge cluster that I'm putting in my 89 CRX. I have a B16 in it but I used my cable speedo. I know that I have to do the electric speedo conversion to make the speedometer work but I'm confused. Where would I buy the electric speedo? Could some one better explain this whole process to me?
Thanks

 

i wonder if its similar to the ef si-r cluster. i have one up for sale.

 

you can use am electronic vss from a 92-95 civic. it hooks up like so..



you will splice the signal wire from the vss into the orange wire at the cluster, and then also into the yellow/white wire so that the ecu will know the speed.

this will also prove helpful for you i imagine

Thanks. That helps a lot. Is my ecu confused now because I am using the old cable speedo and its not getting a signal?

 

shouldn't be a problem. the cable speedo signal is converted at the cluster into a digital pulse that is then sent along to the ecu.
