Here it goes:1.Presure Differential switch on firewall 1/4 vac. line goes to Thermo Switch (blue) outer nipple- Inner nipple from Thermo Switch goes to intake lower nipple 1/4 vac.line. 2. Pressure Switch (Blue) on firewall goes to back center of manifold and tee's off to Turbo Gauge and Over Pres.Switch. 3.Vac. Resevoir (Black Can under Brake Master Cylinder) goes to center back of manifold. 4.Charcoal Filter under front driverside fender (under battery) small vac. line and larger vac. line from char. filter goes to 2 nipples on intake manifold behind throtle body. One of the larger lines T's off to Distributor. As far as I know this is the way the vac. lines go.Hope I didn't leave anything out. If so someone will add to this. GOOD LUCK, Charlie
