Hi
I have a series 2 E- type, 1969. Installed 123 electronic ignition in the summer of 2011this caused the rev counter to misbehave above 3000rpm. I sent the rev counter off to Speedy Cables to have a conversion done and a month and ?100+ later just received the unit back.
In the original unit there was just one green wire to spade connector which I presume is the (+)? In the new unit it also has a yellow wire with an instruction note to connect "to signal input points side of ignition coil or tacho output of ECU". Presuming it's the former please could I have some advice on how best to make this connection? Will I need to run a wire all the day over to the coil near the rad' or can I connect in to this somewhere under the dashboard?
Any help on how to best do this and what to watch out for would be most appreciated.
Many thanks
