i have a set of oem fogs but i'm missing parts of the wiring kit (ie relay and a few plugs). can someone tell me how to make my own wiring kit from scratch and how to wire it?

 

I don't have the OEM kit.. but this will work for pretty much any foglighs... I'm assuming you don't want to shell out the money for the OEM wiring kit for the full OEM look...anyway.. you can buy generic fog light wiring kits which come w/ a fuse for the battery/power sours, relay, wire, switch, and some crimp on terminals..

or I guess you can buy those separately yourself...

fused power to battery
might as well buy a reel/spool of black and red wire
a good relay like Bosch
a switch.. you can buy a lighted one heh..
solder and soldering iron if you don't already have one, and some connectors and insulation..
some wiring conduit and zip ties or electrical tape to clean it up..

relay:
I think its
30 to fused power
85 to ground
86 to switch power (switch)
87 to fog lights

first make a plan/route on where your wiring everything...
wire fused wire from battery (don't put in fuse yet.. do this LAST when everythings connected) to relay terminal, and get a clean ground to relay and fogs, you can make a "Y" split wire to the 2 fogs if you want, then wire the relay to the switch, a ground for the switch, and a 12 volt "switched" power for the switch so that it only activates when your ignition/car is on.. and that way if you forget to turn off the switch.. the lights go off when ignition is off so you don't "forget" to turn it off and drain your battery... after everything is connected and all your connections are secure and insulated (battery, relay, grounds, fogs, switch, etc... )then plug in the fuse, turn ignition to on and flick switch to ON and see if they light up...

good luck..
