That is super interesting Ed - thanks for sharing that. All the factory tach transmitters I have ever seen were screwed to the firewall next to the fuse block or mounted to the drivers side inner fender next to the firewall, and in one case screwed to the firewall vertically adjacent to the master cylinder. Never heard of one being mounted out front so far from power and the distributor, but I guess you could certainly do that. just have wires all the way up the inner fender that way is all - if you have window washers you could strap the transmitter wiring to the fluid hoses I guess.
