Default Missing ABS Control Module

The bus is in the shop and the techs cannot locate the ABS Control Module. So, it's not really missing - just hidden. Any BMC Woggers out there with suggestions?
Thanks in advance.

The only "main brain" I have seen is the brain mounted on the bulkhead just above the front axle forward of the fuel tank. Have not been under there since last annual service last September but I think it is there. If memory serves all the wheel sensor wire cables lead to it there.

Thanks Brad; I'll relay the info. Makes sense that all sensor wiring would lead to it.

Default '97 BMC ABS

Found, fixed, and functional. I was tracking down another problem (more on that in another thread) when I found the Midland-Grau 'control box' and the related valve control unit. Thanks Brad W, it was exactly as you described. Pic 1 shows the location: the inside of the FR tire and the FR airbag are visible. Pic2 is the problem: the molded female connector was dry rotted and broken. Pic3 shows the repair: I tracked down a short ABS connector cable and cannibalized the female end. Now the ABS goes thru its start up sequence and the light goes out as it should!
I know some (older-experienced-crusty?) 'Birders don't care about ABS. But hey, if the technology gives me just a slight edge when it come to keeping my 42K+ lbs under control and upright, I'll take it. It was also fun to find and fix it! The adventure continues!

Dan, thanks for your efforts on figuring out the abs brake problem. And the bodywork and lights look great.
See you soon at WOG.
