Hopefully someone can explain how this relay works?

Do you have a scan tool? If you do, are there any DTCs?
Will the engine light off an aux fuel source?
Please don't spray anything into the air filter.
Just a little wd directly into the throttle bore.
A little!

Have scan tool, obd2 port is dead. Has power and ground. From what I have been reading if the CAN has no signal the scanner will not work.
Sorry, but how can I tell anything from those pictures.
They show up on my phone just fine. After dinner I will print them and take a picture of them with my phone and post them.
