I have a few questions about this. I removed the ball underneith my hood, Nothing was connected to it but i removed it and the check engine light turned on. I didnt care then like 1 mile later it was fine again. What is this box?
I plan to remove my hood squiters, And i see if you unplug the washing fluid sensor it clicks the check engine light on, Can i just go get this light cleared and call it good? Same with the intake. Thanks!
Also, How can i check these codes

The ball makes the heater switch quicker, you might notice it changes where it blows under full throttle. Make sure you capped all of the vac lines that went to the ball.

Without knowing what year your truck is it is imposible to tell you how to pull the codes. If you have obd 1 you can do it with a paper clip. If you have obd 1.5 or 2 then you would need a code reader.

Its a 96, And their was actually no wires or anything running to the ball, I will look for them next time i work on my truck.
Also, can you answer my qestion about clearing the codes? Thanks!
