False, the small red wire is just a remote on signal, and works perfectly with the ballast source originally made for the stock coil wiring setup. Its on owner choose keep it or not. Old MSD instructions sheets said the need to remove and splice wires together ( or whichever method you preffer to use to bypass ballast ), but laters instruction sheets were updated and specifically says the coil + lead wire can be used for that signal even with the balast still on firewall.

Where the ballast needs to be removed is on RTR distributors, because they don't have the power source separated like the modules get [/quote]

I know exactly what the small red wire does.

Do what you want.................

I'm done with my input.
