What is this?

Looked in the tm last night but couldn't find it in the first 400 pages. Figured I'd ask before looking again tonight. Is it associated with the chemical detector, or does the detector mount on top?

It's mounted in top of the air breather.

I thought I took a more clear picture, but here are 2.

ABS module

Awesome, thank you. Does anyone know if it's been mounted elsewhere on other vehicles? I'm switching out air breathers and am assuming I can mount it above the tranny on a rail. (along with the hydraulic to air module)

M43 chemical detector?

I think the ABS controller is mounted there on all trucks.

Only A1 trucks have ABS. Chem detector mounts above it or above the air hyd box.
