Speedo on S14 with RB25DET? How to?

[underground]

Hey Guys,

I got a car that I'm working on...It's a RB25DET S14 which has a tach and speedo that dont work...I'm not sure they are even hooked up..

I know I can get the tach reworked from LS Auto, but what about the speedo?

HELP!

The main question is if they used the RB lower harness or the KA lower harness. If the RB lower harness was used, you will have to run a wire from the speedo sensor to the cluster (maybe the ECU, I can't remember). If they did use the KA lower harness, see if everything is hooked up correctly or not.....
