Does anyone know how accurate they are appossed to an Autometer 2 5/8 tacho?have a funny feeling the original one is slightly out, im gonna put the autometer one back in as well for a bit and see how good they both are.
Thankyou for all who helped me out with the info for this....... :-)

Stuey,
On Aussie models it's Black/Blue tracer.

Hey there, in regards to this post of wiring up the tacho, does anyone know
what colour the wires are behind the dash, ie this piggy back wire wrapped
in tape, and also the colour of the possitive coil wire from the loom on the
positive side of the coil...... thankyou.....
