ok i got a new smiths tacho
yes i ok green to green , black to black, red/white to red white.

"Red/blue Tacho output from ECU or contact breaker or to alternator 'w' terminal."
or the white/black.

"brown/slate Pull up for open collector ECU out put "


and it looks like I need to switch from 2 to 4 fuses, and the pervious owner was creative with the wire colours spliced in.
