    guys i recently bought new OEM JDM amber/yellow fog lights but have been having a hard time putting them on. My question is, the relay box that you have to screw somewhere...what is the best spot for it? If anynody has pics of the wiring in the motor can you please post them so i can get an idea?

    assuming you bought that crappy set from ebay.. which BTW are NOT OEM.. and hell nah.. not even remotely anything that should be called JDM either... considering there are NO JDM PARTS FOR THE tC..

    follow this diy i put together:

    FYI, yes, this will be connected to your parking lights (they will only turn on if the parking lights are turned on), and will also not turn off when you turn on your highbeams.. you can always turn off with the switch.

    let's take a look at the main wiring harness first..

    what you do is cut the relay off the main harness (cut the blue and black wire leaving some extra on the relay itself... you'll need the slack)

    also with that stupid extra ground wire with the connector on the relay... cut that completely off.. you'll have enough black wire on the relay from what you cut off already.

    done?
    reconnect the black wire that you cut off with the connector onto the main harness, use a butt connector or something.. this'll be the ground for the fogs themselves. connect it to this.. sure..

    for the remaining blue wire on the fog harness, tap that into the stock optional fog connector located inside your driver fender.

    tap the blue wire into that pink wire. install fogs, connect to fogs.. and you're done with the front.

    now you still have the relay and the switch in your hands.. we go inside into the car.

    inside there will be the optional oem fog connector... from there, there are 6 wires in the connector.. we will be only using 4 of them and tapping the relay into it as such.

    now at this point you still have the inline fuse connected to the relay.. cut that off and leave the remaining red wire hanging out. the oem fog circuit is already fused, you don't need the one they gave you.

    now cut the white wire from the relay short so you're able to just connect it directly to the switch's white wire. no need for that extraneously long extra wire...

    so let's see what we have now..
    two red wires (one from the switch, one from the relay),
    the white wire from the relay should be connected to the switch's white wire...
    you have a black wire from the relay hanging out, and a black wire from the switch
    and then the blue wire from the relay hanging out.

    connect the two black wires and tap them into the orange wire in pin 5 of the connector.
    the red wire for the switch goes to pin 7.. light green wire.
    red wire on relay, taps into orange wire in pin 1
    and finally the blue wire, taps into the pink wire in pin 2

    why'd i do this?
    running wires thru the firewall.. SUCKS
