                Hi all,
 Just want to know if someone could help with the wiring for a hk tacho.
 I know the green wire goes on the negative side of the coil but where does the other wire go to and what colour is the wire ?
 
 Some one before me as wired it like this, green to negative side of coil, white wire to positive side of coil but my guess is that this wrong ? White has been joined under console and this wire should go to 12v ignition source ?

                When I put mine (186S HK gts) in there were 4 wires from the back of the tacho Black - earth Brown - through firewall to negative side of coil Pink - up under dash to rear of fuse panel #5 I think. Grey - up under dash to rear of fuse panel #10 I think. If you have access to the supplementary shop manual for HK there is a diagram there.  Would post copy of mine but many thousands of miles away at the moment. I saw some images on the web of replica tachos with brown, pink, grey and green wires.

                Ok thanks.
 #5 is a tell tale I think, so would be ignition source ?
 
 Thanks
