95 Pathfinder tach wire hookup

I installed a bulldog remote starter in a 1995 Pathfinder.  It works but it is hard starting.  The diagram I have shows the tach wire to be hooked to the white wire at the ECCS.  I can't fid the white wire.  An alternative is to hook the tach wire to the negative side of the coil.  I did this and programmed the remote for tach mode but the vehicle still has a hard time starting .  It takes about 6 attempts before it will sputter and finally start.  Can anyone tell me a better location for the the tach wire hookup or where to find the white wire at the ECCS.  The distributer cover says ECCS but there is no wire there.  Please help a guy out.

The astrochart shows the tach as being a blue wire at the coil....?  MAYBE  ?
