Hey guys,

Looks like an earlier year anitlock brake control unit. My 90 nor my 95 have that, my ABS is a box mounted lower on firewall.

Thanks.... And my truck is 1990 GMC Safari cargo... so that's weird.. My mom's 1990 astro doesn't have this... or did her older 1989 astro have it

Is that where it is mounted?

Mine is way down in the belly of the compartment.

Mine quit working 10+ years ago and has been unplugged ever since.

That black box is actually the RWAL (rear wheel anti-lock) brake module.

Like James from BC said, it's the rear wheel anti-lock brake module; my '89 has its module located in the same place as does your van. Well, to be honest, it's not there anymore because it didn't work, so I yanked it.
