Firing order:
1234
Each cylinder has its own coil, hard to foul that part up.
Do your self a favor, buy an OEM service manual for your motor and use the seloc for a mouse pad or something

On the inside lower ends of the cylinder heads there are two larger hoses leading to the thermostat housing. The thermostats are in there. The diagrams for the exhaust housing show the parts. The Seloc does cover the thermostat replacement fairly well. You should consider buying the kit rather than just the thermostats.
