[. . . ] These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement. IMportant saFetY InForMatIon 1. Install only on 12 VDC, negative ground vehicles. Make sure that bracket and posts are unbent before connecting. [. . . ] Use holes in Gauge Set Frame to mount the Set on dash. Follow the specific instructions listed below for installing each Gauge. 4. Remove oil light sender from the side of the engine block and disconnect the wire from the indicating light on the dashboard. Connect the coiled end of the tubing to the engine block (where the oil light sender was removed) and the other end to the Oil Pressure Gauge. Use plumber's putty (not included) to prevent any high pressure leaks. See Figure 1, below. Adaptor 1/8" To lighting circuit Tubing Dash Panel 2. 8. 15. Union Nut 1/8" Tube to 1/8" Male NPT Connector 1/4" NPT to 1/8" NPT Reducer (Used on engines with 1/4" Oil Tap) 1/8 Tube to NPT Connector 1/8" Union Nut 1/8" Oil Gauge Engine Block "T" Piece Figure 1 SKU 65210 For technical questions, please call 1-800-444-3353. Page 2 3. When required, use adaptor bushings on all cars that have larger oil gallery taps. See chart below for typical gallery tap sizes. Ford GM Chrysler Independent (Rambler, Willys) 1/4" 1/8" (Most) 1/8" and 1/4" 1/8" A. ) Mount Ammeter where desired and route the wires from Ammeter through the fire wall and to the magnetic starter switch. B. ) At the large solenoid terminal, disconnect all wiring EXCEPT for the heavy battery cable. C. ) Gather all disconnected wires and group together using a nut and bolt. D. ) Connect one Ammeter wire to the group of wires and insulate to prevent wires from touching chassis, body or engine of car. E. ) Connect other Ammeter lead wire to magnetic starter switch terminal, where the heavy battery cable connects. (This is the same terminal where wires were removed in step "b"). F. ) Keeping the engine off, turn headlights on and observe the direction of the Ammeter needle movement. It should point to the left or "-" (discharge). If it points to the right or "+" (charge), reverse the position of wires at rear of Ammeter. G. ) Once proper indication is achieved on Gauge, securely tighten all connections. Make sure no parts of any exposed wire conductors touch any grounded part of the car. In cars with a separate mounted junction terminal or a horn relay (such as GM) refer to Figure 3 (below) during the following steps: To Starter Mounted Solenoid Ammeter Horn Relay 4. To install Oil Pressure Gauge with functioning indicator light, insert bushing, nipple and "T" fitting (not included) in place of present oil light sending unit on side of the engine block. Connect the tubing to one side of the "T" fitting and the other end to the Oil Pressure Gauge. Then connect oil light sender to the other side of the "T" fitting. 5. ammeter gauge 1. note: To install Ammeter correctly, make sure that all added wiring is the same gauge (or larger) as the wiring found on the car (typically #12 or #10 AWG). [. . . ] D. ) Connect the other Ammeter lead to the solenoid battery terminal post. E. ) Follow Steps F and G, on previous page. To have Gauge Set lights operate off the same switch as the dashboard light, splice the wire from the lamp bulb socket into any wire presently used for lighting instrument panel. Be sure that mounting panel is electrically grounded to chassis of car to ensure steady gauge indications and light intensity. [. . . ]
