As a safety precaution, the +12V wire attached to the positive I (+) terminal of the gauge should be fused before connecting to the positive (+) output side of the ignition switch. We recommend using a 4 Amp, 3 AG fast-acting type cartridge fuse (Littlefuse® # 312 004 or an equivalent) inline between the power supply source and the I (+) terminal on the gauge.
NOTE: Some late model vehicles use electronic sensors in their pressure and temperature senders for engine control functions. Before removing the original sender, we recommend that you contact your automotive dealer to be sure no critical functions will be disrupted. With pressure gauges it is beneficial to add a T-fitting to install your new gauge and to keep the warning light operational. This allows you to monitor the pressure and still have a warning light to indicate emergency conditions.
NOTE:: Disconnect negative (-) battery cable before installation.
CAUTION: Do not touch ignition wire to the sender (S) terminal on back of gauge or the sender may be damaged.
Replace light bulb with the same number bulb as the one removed.
