A few years ago we installed a complete MSD ign system in the 64 polara..512 cid ...has run fine but we kept the ballast resistor..I'm sure I read the instructions and would have by passed it if I was told to..but now I'm hearing not to use the resistor..so do I just connect the 3 wires together.. It's a 2 prong resistor ,but one side has 2 wires..
