Phase 2 Tacho Wiring

[jimmer 0]

after removing some of my wiring loom that was redundant i appear to have lost my tacho. Does anybody know what 2 wires on the instrument panel are needed to run this? Any help much appreciated

The tacho should have three wires going to a four pin blue plug which fitsinto the back of the clocks, power (white wire iirc), signal (blue wire 112) & earth (green & yellow) iirc.
