Which vehicle / OS to use for instrument cluster

Full-size vans built with a Gen III engine could have been equipped with a cable activated throttle body (DBC) from 2003 to 2006. Only in the final year for the Gen III engine in full-size vans (2007) was the DBC option no longer available.

On the vans, it depends on whether they had ESC or not. Vans with ESC (starting in 2004 on passenger vans only, due to numerous rollover lawsuits from parents of school children who got transported in those vans regularly, and teacher who dont know how to handle a top-heavy van in an emergency evasive maneuver, GM put ESC on passenger vans starting way back in 04) had drive by wire obviously, since ESC/TCS needs to have authority over throttle control....but non-ESC-equipped vans (cargo vans) had cable throttle up to the electrical system redesign in 2008, when they moved to GMLAN architecture and thus moved to the E38 controller and Gen IV engines.

So if you're looking at vins, "JL4" is stabilitrak (ESC)...if the van you're pulling an ECM or engine out of has JL4 on the RPO sticker, its going to be drive by wire. I think "KUP" is another electronic throttle control RPO.

Thanks for the explanation Ben, makes sense as the E38/Vettes couldnt do Class 2 and therefore relied on the BCM. Interesting how the "crossover years" worked...
