Aux outputs
There are three aux outputs.
Aux 1a low-side output, i.e. it switches to ground. Maximum current 3A.Aux 2a low-side output, i.e. it switches to ground. Maximum current 3A.Aux 3a high-side output, i.e. it switches to positive. Maximum current 6A.
The Aux 3 output can directly drive reverse-light bulbs, without any additional relay.
The source for the Aux 1 and Aux 2 outputs is the ground on pin B8 GROUND. Under a higher load on these outputs, the ground wire running to pin B8 GROUND must have a sufficiently large cross-section, 1.5 mm² (16 AWG) recommended.
The source for the Aux 3 output is the positive on pin C8 +12V CONST. Under a higher load on this output, the positive wire running to pin C8 +12V CONST must have a sufficiently large cross-section, 1.5 mm² (16 AWG) recommended.
