Plug-and-Play HID Fogs Not Turning On
#6
T-Dogg.. Use a temporary ground and power wire and run direct to the battery - just to test - and make sure your ballasts and ignitors are working ok. If the stuff works fine, then it's probably the voltage or power going to the fog lights, in which case you would need a relay
Basic Relay setup; the relay should have the following wire/connections:
Ground
Constant Power
Activation Switch
Switched Power
The setup would be something like:
Ground to chasis ground
Constant power can go direct to battery [in-line fuse might be a good idea]
Activation switch would goto power wire for stock fog wiring
Switched power would goto power wire for ballast/ignitor pack
Since we know what the ground does i'll spare the details, but the rest should work as follows
Turn the fog lights on, the stock power wire which you have hooked to the relay 'activation' lead gets power and throws an internal switch, filling the gap between the constant +12 (which goes no where until switched) and the power output wire, aka your ballast power wire, providing +12 to your ballasts and lighting the gas.
