Figure 7 on page 24 shows the connectors for the 10 A relay cable assembly on
the back of the amplifier/relay module. The relays are fused on top of the module
with 10 A mini-blade fuses. Extend wiring with 18 AWG leads or thicker. Insulate
spliced leads with twist-on wire connectors. Fold and seal unused leads.
