Alright, so I just bought a 90 Hatch and I'm having trouble identifying where these connections go. They're both male ends. From the diagrams I've read, I believe the larger of the two is part of the main harness. The under the driver's side, left hand drive, Ka24e. (Side note, my tach and spedo don't work- could this be part of the issue? Haven't checked to see if the sensors are hooked up).
