Cole, The yellow should be for the "dash" light. You can take the back off and see where it goes, or touch it to a 12V hot wire and see if the lamp lights.
My guess any shift light would have to operate off the green wire, since it picks up the signal for the rpms.
Lucky me, mine has the dial on it and I set it for 4000 rpms, and only run it to that range in second. aint got enough hair on my butt to go there in third.
