I don't know too much about this stuff - except I have had issues trying to drive too much electronics off the TD circuit. I contacted a guy that makes a tach adapt unit - for using a 4cyl tach in a 6 cyl engine etc. Basically his unit takes the 'relatively weak' TD tach signal and converts it to a more solid signal and I think a slightly different shape - but basically more robust. It is possible there is nothing wrong with what you have been doing, except the stock TD signal is not enough to drive what you are trying to utilise. In which case inserting a Tach Adapt into the TD loop may be a solution.
