Those should be the # on the ecu, the connector # should be t1-9,t2-10, t3-21. these line up with your numbers.
color codes should be
t1-blk/yl
t2-blk/wt
t3-blk
couple of quick things to try first.
compare omh readings from blk at ecu end back to coil connector with the other two.
In other words ,check resistance of the wire from coil back to ecu for each coil at both ends for resistance.. and also check each to ground.
A scope would be nice , but I would also go into the pin 8 of the diagnostic box with a code tool and see if you have a code 21 .
Can you build this tool ?
