SES light stays on when first start

hey guys i just got done putting in new UVCH and gaskets in my truck because they were bad. well i put on the valve covers and plugged everything in and started it. well you know how the SES light comes on right as you turn the key on but then i usually goes off. well mine didn't. it stays on even if i don't start the truck it is on. and even after i start the truck it stays on. its not all way together yet i still need to put on the intake and intercooler pipes and i didn't plug in the A/C plugs onto the compressor. just basicly the engine harness above the drivers side valve cover and the plugs that go into the injectors.

it runs great so i don't think it is anything under the cover. but i didn't keep puting it back together just in case i need to tear it back apart. any help would be great

You need to get everything plugged back in before you can say something is bad.
