Hello Group members,

I got a pair of PIAA 130/110 input headlights which give an output of
200/150W. Since this is high wattage and I dont want to burn out my car's harness, so I also got a Bosch relay system which can support a max of 600W.

The relay system has 2 female socket connectors to connect to the headlight bulb and each connector has a ground wire. It also has one male socket connector to connect to any one car's original headlight socket.

There are 2 wires which go to the 2 fuses of this relay system. The place where I am confused is the instruction manual says that I should connect the main wire to the positive terminal of the battery but there are 2 wires instead of one. Do I need to connect both the wires to the positive terminal? Where does the relay systems get the negative from battery.

I would appreciate an early response.

Thanks.

By the way I got this entire kit for $80

 

Its probably one for high beam and one for low beam. In that case, then you would connect both of them to the positive terminal. You should check the instructions.

 

Thanks.
