Hey all, installing a Sun Pro (it will work for now) tach in my 79' Malibu. Right now I'm replacing the speedometer cable and thought well I might as well run the wires for the tach. Would it be a problem if I ran the tach signal wire (green) next to the speedometer cable through the firewall grommet and into the engine compartment? If not it's no big deal but if it will save me some time and not have to drill the firewall for a tiny wire, that would be awesome.

Alright cool thanks for the response. I figured it would be okay since all the wires have insulation around them but I just wasn't sure.
