I have a grey and green coolant plug leftover from the Accord wiring harness. I'm putting a H22a in a 95 Accord for reference. Just wanted to confirm which goes where. There's a temp sensor on the cylinder head and a temp sensor on the water neck fitting where the upper radiator hose routes to.

Here's a pic for reference:

 

Not sure, but I know that on my 97 Accord the green plug goes to the thermostat inline w/ the lower radiator hose.

 

the green one plugs in where show....the grey one just look for another connection not connected on the trans possibly
