Help! (BEFORE THE WEEKEND)

[jbonina@nectech.com]

     I'm installing the ingnitor electronic ignition tomorrow. 
     ('73 tr6)
     
     2 things:
     
     directions state you must use a coil w/ a min. of 1.5 Ohms. I don't 
     own an Ohmmeter (?). How important is this?
     
     and, the directions state 'for installs that use a ballast resistor,  
     it is preferable to connect the red wire to the ignition side of the 
     resistor rather than the positive (+) terminal of the coil'. 
      How do I know if my TR has a ballast resistor?
     
     I'm leaving the office in 30 minutes. Any input is appreciated.
