Hey guys,

This is my first overhaul i've done, just have a couple quicks questions, any pointers greatly appreciated!

Whats the difference between grey plug vs yellow plug engine wiring?
I'm reusing a hks mhg, going to remove all existing viton and apply copper spray, but how exactly do i apply it?
What is this additional sensor on the thermostat housing?
