2. Diagram 2. Installation of the switching module on a dual headlight system where all load is removed from the headlight

switch and direct battery power is supplied to both the high and low relays. A typical GM style headlight switch, such as

that used in all American Autowire kits, includes an internal 28 amp circuit breaker. This kit modifies the typical stock con-

figuration by operating the high and low beam relays with direct battery power. This bypasses the internal circuit breaker in

the headlight switch. Therefore, a separate circuit breaker is required to protect the relay power input. The power input can

be a separate lead from a battery circuit on the fuse panel or tied into the original battery power input to the headlight switch.

It is important to know the amperage draw requirements of your headlight system as a low capacity headlight switch may

be a weak link in this chain. This configuration eliminates a headlight switch capacity problem.

3. Diagram 3. Installation of the switching module on a typical quad headlight system. This is the same situation as ex-

plained in Diagrams 1A and 1B except that there are four headlights as opposed to two. The explanation is the same as in

Diagram 2 concerning the power input to the relays.

4. Diagram 4. Installation of the switching module on a quad headlight system where all load is removed from the headlight

switch and direct battery power is supplied to both the high and low relays. The explanation is the same as in Diagram 2

concerning the power handling capability of the headlight switch being used. Keep in mind that you are still limited to the

maximum 30 amp draw of all the headlight high beams and the maximum 30 amp draw of the low beams as dictated by the

relays. While it is unlikely that the headlight circuits will require this much amperage, bear in mind that this module could

not be used in such a situation where the relay capacity was exceeded.
