Putting the finishing touches on a 72 SS Chevelle. We have all of the gauges in the dash working with the exception of the tach. The only reason that it isn't working is because I can't find the wire at the firewall. I have identified the brown wire at the PCB but I am not sure where it exits the harness and/or where it passes through the firewall. Can someone shed some light on this for me. Thanks, Dan "It is a mistake to allow any mechanical object to realize you are in a hurry." http://www.freewebs.com/chevelles1970/
