LS Tacho Fixed

[RexCars]

The tachometer has been nonfunctional on my LS for quite some time. I printed out all the wiring info from the manual and went to Jeff Greenfield's shop in Lenox, where we discovered that the problem was in the wire from the Bosch ECU to the connector under the hood behind the false firewall.

Because the tacho signal wire goes through the firewall not just once but twice to get to the instrument cluster, it seemed simpler to just run the new signal wire from the ECU to the tachometer inside the car behind the dash.

Anyway, now it works again. Its odd that this wire would break in this fashion, given that it runs in a big bundle that is not subject to flex, but there you have it.
