Blue Wire/ABS

Thank You for taking the time to help me out with this!

 

The T800 is a B, i thought the B was just a different nose.

 

When i purchased the W900L back about 5 years or so i asked the salesman from Coopersburg KW about the difference between a T 800 and a T 800 B and he said there was no difference, but when i purchased the T 800 B the inside of the cab is different but the only difference is the dash board which i thought was different because it was a flat windshield versus the W 900L which has a curved windshield which has a deeper top to the dashboard.
After owning the T 800 B i noticed the nose is shaped different then a regular T 800,plus the headlight box area is molded into the side of the nose, a regular T 800 has a gap between the side of the nose and the molded headlight area, i also looked at other T 800's on truck paper which verified the nose difference, i never noticed any difference other then that, except i replaced the HVAC control box and harness on the W 900 and lost the tape markings i put on the W 900 where each air line goes and opened up the T800 to copy the line locations and noticed they weren't marked like the W 900 is.
