In finalizing some winter work on 1989 Invader, I'm considering converting from the points/condesor setup. To order the correct coil/module combo from Pertronix, I'm asked if there is a ballast resistor - the VP owners manual doesn't show one, only 40A fuse and Relay. Can anyone help me answer this question and/or locate the resistor? Is it a separate piece or integrated with a relay? Attached photo shows what I believe to be 40A fuse (A) and Relay (B). Thanks!
