I called Pertronics and explained what I had and asked if I used the pink resistor wire to my yellow top, would it hurt my coil. His answer was no harm to the coil. If you do send 12 volts to the 5-9 volt yellow top, it will most likely fry it as Bob Gaines and couple others have mentioned So I pulled the dizzy points plate and installed the 1281 Pertronics plate and pickup on my 65 GT350. Rotor was really nice as was cap contacts so they went back on. Mechanical advance was set to the 13L stop on the relucter giving me something like 26 degrees mechanical advance. Hit ignition switch and it fired right up. Set initial timing to just under 13 degrees giving me 39 degrees total advance. Haven't yet checked to see how close it is to the 39 degrees as I don't have that type light. Throttle response was immediate as was idle. Much more crisp than the points setup. Getting ignition upgraded and installing the 715 Drew P at Air, Fuel and Spark rebuilt has really changed the attitude of the engine. Although haven't taken it on road, it sounds like it really has an attitude now...Hardest part of the conversion was getting screwdriver on the plate screws without hitting (scratching) the fender to fender brace. Haven't yet reconnected the 65 tach as I will be installing a 2A inline fuse to help from frying it (thanks Bo).
Anyway, hope this helps.
