SLW42 Posted April 16, 2009 Report Share Posted April 16, 2009 the black wire should go to the negitive of the ignition(to tell what revs it's doing) and then red goes to ignition power(so when you turn the key on the tacho turns on and then you have the power wire for the lights which is self explanitory run it to a park light wire what brand of tacho do you have if it is autometer there wil be two wires that come out the back of the tacho and you will have to cut a 1 wire for a 6 cylinder and both for a 4 banger and leave them alone for a v8 speco meter i think there is just a switch at the back of the tacho for how many cylinders it has Quote Link to comment Share on other sites More sharing options...

Jason Posted April 17, 2009 Report Share Posted April 17, 2009 I though 4agze ecu's have a tach out? Quote Link to comment Share on other sites More sharing options...

Kebin[RL] Posted April 21, 2009 Report Share Posted April 21, 2009 Build this circuit and wire it to each of the two coil packs to have an accurate tacho output. Quote Link to comment Share on other sites More sharing options...

the witzl Posted August 17, 2009 Report Share Posted August 17, 2009 (edited) They don't. Incorrect.... mostly. You can use the IGf signal as a low level (5V) tacho signal. I'm also quite certain that the ignitor has a dedicated tacho output as well. If you have an old style tacho that used to connect to the coil negative terminal, you might need a tacho booster to get the tacho to work from the low-level tacho signal.
