The only things with wires upstream of the manifold are the TPS and IAV. As I described, there's the snorkel, air cleaner box (lots of hoses, no wires, only the air filter and a crankcase vent mesh thing inside), 2 separate tubes snaking to the twin bore throttle body. ********.com doesn't list a MAF for this car/van/truck. I'm not surprised because our '97 Caravan 3.3 doesn't have a MAF either.
