Throttle body has connectors (in addition to central huge input and output): Bottom: 1. Anti-freeze hose from thermostat 2. Anti-freeze hose to liquid cooler (water) pump 4. Air hose to metal commuter (mini manifold rear of intake manifold) 5. Air hose to control valve on steering rack Top: 3. thick hose to vacuum switching valves (pair), with intermediate round gas filter 9. thin hose from charcoal canister adsorber - intake of gas air petrol mix (since 1991-05 in SERA03 with gas filter, before - direct plastic pipe) 9.1. For SERA03 one more VSV added to adsorber canister hose /90910-12121, SERA01 has direct thin plastic pipe from throttle to adsorber charcoal canister Intake manifold has extra pipes: 8. out to MAP (manifold air pressure) sensor with gas filter on pipe d=4mm 10. splitted with 11. rear middle dual input from VSV (both) 12. input from fuel bypass valve (petrol return and pressure regulator) to cylinder one bypass 13. crankcase ventilation middle hose (with valve on cam cover) to intake manifold (managed by PCV=positive crankcase ventilation valve) 15. rear vacuum hose to brakes 16. right side outlet to electric idle valve, hose goes to metal commuter pipe Air bypass way for cam ventilation: 14 . hose from cam cover left side to filtered air flexible huge hose before throttle , used to take clean air into cam |

Air bypass way for cam ventilation: 14 . hose from cam cover left side to filtered air flexible huge hose before throttle , used to output extra gas from cam to intake (similar to PCV nearby)
