New Tic Toc Tac will not work. "HELP"

[race57]

This has probably been answered somewhere before but I am new so please excuse me.
Following the limited instruction on the tic toc tac, I did as it says "blue wire to fuse panel grey wire to neg side of coil" No instructions on how to wire the clock. So the way it sets , the clock only works when the key is on and tach does not work at all. Are there more wires that need to be hooked up ? and if so where? This is on a 1968 dodge charger.

Found this on another site hope it helps

I don't have an OEM tach so I can't say for sure. Mine originally only had a clock like yours, which I replaced with a charger specialties tic-toc-tach and a tach harness from Evans wiring. Give him a ring and order the correct one. The harness I got only has two wires. The original clock connection plugs straight into the tic-toc-tach clock plug (white). The two wire tach harness has one wire (blue) which draws power from a keyed 12v power source (I chose radio spade on fuse box) and a (gray) wire which connects to coil negative.

The hardest part was drilling the hole in the firewall for the gromet (it's quite a large hole). There is a dimple where the hole needs to be drilled so you can't really mess it up.

Surely someone else will chime in that has replaced a clock with an OEM tic-toc-tach.

Ok it's working now. the tic toc tac wiring harness has two wires one blue and one grey, the tic toc tac has three post that have a "G" printed below them. (ground which hooks up when the dash is installed) there is a long post marked with a "B" below it, this is where the blue tac wire goes from the harness, then there is a post with a "8" below that, this is where the grey wire goes, that goes to the coil. There is also a grey wire pigtail conector coming out of the side of the tach, this is where the power for the clock goes. Where I got confused was at the coil post, I had to use the wire clip from the old clock so I could hook up the coil wire.
