Ok so I have a 1973 23' executive with a 455 Olds, I bought a HEI distributor from a 75' cutlass because the old distributor died on me on the water and a boat mechanic out there told me to upgrade to HEI(there was oil inside the petronix electronics) Question #1 do I put the wires back on the cap just the way they came out?(looks like the 75+ engines have the #1 plug more towards 1 o' clock instead of the 5 o' clock on the 73, also there is power (green wire) and ground (brown wire) on the factory harness with a yellow wire that was not connected also, do I just wire it up green to red, brown to black, and yellow to white(assuming the yellow wire is a tach signal) I have been told to add a ballast resistor but I have no idea what that is. Please help me get it wired up so I can take it out this weekend. Also the distributor I got came with a vacume advance, my old didnt have that, do I just cap the vacume port on the distributor or should I add a vacume line to my carb?
