Toyota / Lexus customers...your need for higher voltage is here and it's 100% plug and play. High-quality Toyota/Lexus spec OEM 4pin connectors, weather pack sealed and epoxied for off road, daily driving fit duties. No water, no corrosion, no electrical problems! Unplug your OEM harness, connect the Mechman voltage booster harness to vehicle plug and then plug into your OEM or Mechman alternator. DONE! Results may vary slightly on non-Mechman brand alternators.
Great for some higher end 12 volt-based AGM batteries and some lithium chemistries where charging voltage is maximized near 15 to 15.5 volts. Be sure to check your battery manufacturer's charging parameters before ordering! Also ensure your added equipment is able to operate at low to mid 15-volt ranges.
