Throttle Control Module Guts

Has anyone ever taken apart a Throttle control module that might have failed in your Suburban - Yukon from 2003 ?

I'm not gonna be able to resist taking this thing apart to see what is in the magical black box.

I fixed two trouble codes by replacing 1) packrat chewed wire and 2) Throttle sensor but now have the 'its your throttle control module dummy' message so I'm thinking I'm taking this apart while I look for its replacement for less tha 120 bucks (tmd1-160a1)
