hey im nearing the end of my obd2b ex harness converion on my obd2b b18c1 and had to splice in the integra connector for the dizzy.. the blue wire coming out of the b18c1 dizzy stops at the plug.. it dosnt go into the part i spliced in.. do i need to pin it in in order for my tach to work?

if so what plug do i need to wire it to? does it go all the way to the tach?

if there is an easier way to do it please bring it up

thanks a lot in advance i want this car donee

 

and if anyone knows where i can findnd the pin out for the dash harness that may help also

 

For OBD2b, the tach signal comes directly from the ECU (A19) to the cluster.

 

sorry forgot to specify that i was using a 96 p72 ecu with conversion harness will it still be run by that?

 

anybody kno? really wanna finish the car
