Description
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!
Why would you need this booster harness?
You're a car audio enthusiast with LOTS of added car audio components and you have deleted the OEM under hood battery and have a dedicated Lithium chemistry-based battery that needs to be charged higher than standard AGM batteries. A well-known battery type for this higher charging is the CMAX type. Please consult your battery manufacturer for proper charging ranges BEFORE purchasing. This version of Toyota/Lexus 4pin booster harness will yield a 15.5 to 15.9 voltage range. Please note that this range is dependent on factors such as alternator brand, type, installation quality, current electrical integrity and operating temperature. Voltage is not a SET number, it reactive based on those factors.
*** MECHMAN DOES NOT RECOMMEND RUNNING 12 VOLT AGM BATTERIES WITH THIS HARNESS, THEY WILL KILL THE BATTERY AND POSSIBLE COMPONENTS CONNECTED TO IT! ***
Quick Example:
Say you have 5,000 watts of amplifier power. You're currently charging in the high 13's-low 14's voltage. While being somewhat generic on numbers for this situation, say that amplifier(s) will need around 360-370 amps of output to fully support making that 5,000 watts. Plug in our booster harness for 14.5-14.9 volts and now you only need around 330-335 amps of output to make the same power. Thats a nice 350-450 wattage bump from a simple plug and play harness!
Vehicle Applications: (these are just popular fitments, please ensure your current alternator has the 4pin style alternator plug and NOT the oval 3pin. If you do not see your vehicle listed and cannot confirm fitment, please email us BEFORE ordering!
