BATT+

The DC-DC will not power on or operate until the D+ ignition cable is connected to the ignition

circuit where it will detect a 12V source to operate ON. The purpose is to toggle the DC-DC

switch on when the vehicle is running with the alternator to prevent the DC-DC from operating

incorrectly with just the starter battery leaving you with a drained starter battery. Use

18-16AWG copper cable. You may need a multi-meter to test your connections to verify

placement of the D+ wire.

Could be labeled as “B”, “Bat”, or “Pos”. This will connect directly to the

battery and typically be heavy gauge for high current applications.

BATT-

Could be labeled as “Neg”, “Field” or “F”. This will connect to ground. Some

alternators may not have this as they will be directly grounded to the engine.

IGN

Could be labeled “IGN” or “L” and will likely be the smaller terminal. This

connects to the ignition circuit or dashboard warnings signs. This is where

you will want to splice the D+ ignition cable.

Check your alternator and identify the number of terminals. Most alternators will have 3 wires

connected (BATT+, BATT-, IGN). The following is an example and may not match your applica-

tion. Refer to your vehicle’s documentation and part for actual wiring
