FRPP wires solid or spiral core???
 

MSD suggests not to use a solid core wire with the msd6a box, and after I put it on my radar detector is picking up something from the ignition and won't work right. I have frpp 9mm wires that are about a year old. If the frpp wires are solid core then thats probably the problem. Are the msd spiral core wires any good?
