I just swapped a 2000 b18c1 in my 95 ls and the tachs not working, anyone know whatto do? someone told me i had to splice into a wire on the dissy, but wasn't sure what color wires to what color wire and haven't found anything in my helms manuals yet or from searching on here.

 

was it working before?

 

it worked in the gsr, i think its obd1/obd2b difference

 

its an aftermarket tach or factory one?

 

make shure the speed sensor is hook back up.

 

its the factory tach. does the speed sensor have anythign to do with the tach in a 00 teg or 95 teg, i know it does in one year of b16, but i thought it was jsut one year of jdm b16, and i had it off but i'm pretty sure its back on right and in the helms i can only find wiring diagrams for obd1 and obd2a and hte updates i have for 00 itr doesn't have any updates for the wiring diagrams so does the blu wire coming fro mthe dissy still go straight to the tach and run it or does another wire control the tach in 00

 

OBD2b do not have the the blue wire for the tach coming out of the dizzy's plug, only going in so there is an empty slot on the opposirte side from the dissy, just put a pin in the place and ran the wire to the driver side harness and there was a blue wire on the fire wall side and an empty slot on the OBD2b engine harness, tach works now, think I'll post some pics incase anyone else runs into this.
