I think it's the ...ECU? or whatever they called it for the electronically-controlled Quadrajets they had in 1985 and '86. My '86 C-10 had one that looked damn similar, but it was in yellow plastic rather than white and not on a big bracket like that. It was mounted on the passenger side where GM later mounted the TBI ECU's.
