I did this yesterday simply for maintenance purposes. I didn't have a light.
I have to say it's almost too easy. I did not see any debris come out other than oil that looks curdled, maybe from the throttle body cleaner causing it to look a little gelatinized?
I didn't mark which harness went to which solenoid. I just connected them to where I thought it came from. So I plugged in the longer wire coming from the top of the engine to the bottom solenoid and one coming from the bottom to thje top solenoid. I believe that's the correct order. Can anyone double check to make sure I connected them back the right way? LOL that's what happens when you do things with a mild hangover
