I've got MSD ignition on my 85 Gt and im going to just be installing an autometer tach. I have to run that green wire to the tach input, but there is no wire coming out of the box right now. It looks like there should be a wire that fits snug into the box, do i need this, or can i still hook the wire up? I dont mind gettin this wire, but whre would i get it, just the MSD site? Thanks.
