Anybody know what amperage the big yellow key-on ignition switch wire coming right off the ignition switch carries? It's the one that provides key-on power to the fuel pump relay and ICM. I'd test it with my multimeter, but the multimeter is only rated for 10 amps and I know for a fact that yellow wire carries more than 10 through it. I just don't know how MUCH more.

Thanks for the help in advance!
