This is a good working cluster. He is installing it in his originally tachless ga16 b13. He brought it to me with a hacked up bunch of wires where he tried doing it himself and had the speedo working and the display lights (door ajar etc). I got the temp and gas going for him, but not the tach. The plug for the tach had two extra wires on the original pigtail that his harness did not. I pinned in the wire and tried the blue/white and both blue/black wires from his ecu with no luck. The other missing wire appears to be for cruise control light so not worried about that.
