I have 74.5 tr6; going to swap out petronix igntor coil for standard lucas; I 
also have ignitor ignition; coil has a ballast resistor- I had originaly left 
attached between block and one of 2(+) posts on the coil-had spliced the 
ignition between the resistor and one of the coil(+)-no problem 6 months ago; 
question now with replacement- coil only has 1 post for pos.vs. 2 and how 
should I handle this resistor issue & its placement with splicing etc and now 
one post?? new coil is 1.5 olm made for resistor system.
