this is how we are thinking of wiring up the igniters

hi am having trouble with the igniter wiring on a bmw e30 m20 2.3 6 cyl we plan to use three of the original siemens 1705 607 single channel igniters with three dual post coils in a wasted spark configuration and also are using an m50 crank angle sensor as opposed to the original system with distributor another problem is there are more wires than shown in the bmw wiring diagram ? these are marked on the igniter as t.d and s we are assuming td is tacho drive. i cannot find any information as to where these extra wires go as all igniter pin outs only list what is drawn in the pic i have attached a pic of the original bmw setup any help appreciated. ThanksÂ
