Wiring and mounting checks before ordering

Verify that your circuit operates at or below 32 V and that the current draw stays within the 0 to 20 A range. Confirm the fuse you plan to use matches one of the listed series and the 1 1/4 in by 1/4 in form factor. Ensure 14 AWG wire leads are suitable for your harness and that the inline mounting style fits your available space.
