EGR light is on?

ok, so this new(old) truck i just got has the EGR light on, im thinking i need to clean it? or get a new one? someone help that knows the motors? its been years since i had my last b22, so i have forgotten ALL about them lol

PS, and point me to the right location to look for it! HA(i told you i forgot about them)

When I used to have the EGR system installed I would just clean it if it needed it (as the EGR light comes on at set mileage intervals not related to actual state of the EGR), and then go under the dash and unplug the black wire from the brown and white wire and plug it in the the to Green wire that is next to it, and then the next time do the opposite.
