So I'm doing the 3g swap and I was wondering what happens to the plug for the regulator from the 2g that is in it now? Do the wires get cut or what do they plug into, because it doesn't seem there is anywhere to plug that into?
Everything you could ever want to know about a 3G swap is in this thread in the "Useful Technical Thread Index" sticky at the top of the 5.0 Tech forum.
Follow jrichkers advice and read the Sticky. When I install mine I think I am going to use the Plug Harness from Fordfuelinjection.com along with my 4 Gauge Power Wire.
