where the HELL do you get a tach signal for the dyno on one of these engines short of removing the IDI & puttin plug wires on it? I talked to Kevin @ PAS and he says he needs either a plug wire or a individual coil feed wire to get a signal. any help would be appriciated, i am trying to avoid ghetto rigging it just to put it on the dyno.

Pink wire that comes out of the IDI wire harness. Put the clip on it, just as if you were putting it around a spark plug wire. Then you'll have to calibrate it for number of cylinders to get it to read the same as your in dash tach.

yep ^^ pink wire on the idi harness. the signal will only be 1/2 the tech, just set the dyno appropriately.

14.82 @ 97 mph

As said the pink wire is tach signal. When I have been on the dyno they always put the clip around the whole wirinf harness going into the IDI cover and it works.
