thanks i have been looking for this too.. I am geting ready to turbo my 94 gsr. I saw that you are suposted to de-pin a22 ignition control module. How come you de-pin this one with the ems? Thanks for your time.

 

thats very useful thanks

 

needed this, THANKS

 

anyone know where the pin for the tach signal goes?? or does it go straight from the ignitor on the dizzy to the gauge cluster?

 

wtf i still dont see the rpm signal

 

OBD1 and OBD2A civics and Integras get their tach signal from the igniter in the distrbutor and from there it goes to the cluster, the ECU isn't involved. Its only OBD2B civics and integras that get their tach signal from the ECU.

 

i have (obd1) 94 civic and hooking up an apexi vafc i found everything else but not where the rpm signal go ... so will i have to run this all the way under the hood to the blue wire at the fire wall ?

 

You can either do that or tap into the wire behind the cluster inside the car, your choice.
