I only have a few wires left, the 12V for the fuel pump is the grey wire on the Fuel pump relay correct?? Also Which wire on the fuel pump relay harness is 12V switched and has 12V constant while cranking??

Which wires under the dash do I need to cut to wire in the speedometer wire and the check engine light off my new harness??

Thanks in advance, all that's left after these wires is fuel lines, pump in the tank changed and exhaust and I'll have the swap 99% done, I can't wait to drive it!
