Tach signal wire?
 

I have no continuity on my tach signal wire from the engine bay to the dash. Can anyone confirm if the black/violet wire in an SC goes directly to the tach without any plugs along the way or if there is a plug where is it located?

Thanks - Chris

I'm searching for this too I believe 1980 and up SCs have the wire going to a TD box under the dash
Then to the tach
Maybe someone can chime in more info

There also is a 14-pin connector towards the front of the relay board and the black/purple goes through that connector to the chassis wiring harness. Check both sides.

T14/12………
 

Chris,

The tachometer wire (black/violet) from CDI to tachometer goes to 14-pin connector @ pin #12 for all SC’s. Do the continuity test for both sides of the 14-pin connector (male & female sides).
