Look at batteries, you’ll see there all connected. Simply add another in the chain, as close as possible. Positive to positive, negative to negative. You’ll need 2 new cables. If there’s room in the battery box, good, If not, you’ll need cables long enough to reach the others. Good time to clean up all the batteries connections, and coat them with dielectric grease, or some permatex ( or similar) battery terminal protection spray.

One or two batteries won't have much of an effect. Four or six more, like for an electric APU , then you need more alternator capacity.

No offence but adding an extra battery for extra lights is not a smart move. Let me explain:
Batteries are for starting the truck, acting as a "shock absorber" for voltage spikes from the alternator and as a temporary backup supply when electrical loads exceed alternator output (ie alternator fails).
So do yourself a favour and upgrade to a higher amperage output alternator because if you run your current alternator at full capacity for extended periods you WILL cook it.Ffx95, God prefers Diesels, Tb0n3 and 6 others Thank this.
