DIY (08' USDM Liftback): ESUSE Fog Light Install v2.0

[Creeper]

Ill try and clarify alittle more. Fogs are going to ground and pin 1. switch is wired up just like tk's picture with ground going to ground spot on kicker panel. it is a base 2007 (maybe the problem?) the switch lights up and turns off like its supposed to. relay clicks. but the fogs dont light up. also i had to cut the connector on the wire to pin 1. as it was the wrong ytype of connector. would the fact that the wire is kinda pushed in there effect it? im gonna try and get the right end peice before i head to work.

Make sure you have a good connection on Pin 1 before trying to turn the fogs on, as they draw a decent amount of current.

TK's picture is just showing the connection for the switch lighting wires. You still have to make the connections to the headlight stalk connector.

ok so i have to make the stalk connections even if i dont want the dash to light up with the symbols? what wires do i use for thouse i only have the ground pink and white on the switches and they go to the relay i don hae he 2 wires like the one in this kit. also would it be easier to just run he fogs through and connect them through the switch? im just at a loss seems like everyone has more wires on their kits then i do

Scott,

I got my headlight/foglight kit from Ebay installed everything (including the relay) but the switch that came with the foglight kit was unbelievably low quality. I bought another switch off of ebay and still waiting for it. Anyways, When i opened the D4 connector on the headlight stalk, the yellow wire that we are supposed to cut-off and connect two wires from the switch does not lead to anything apart from supply ground to the relay right? I dont know why we split that wire and connect the other wires from the switch to the D4 yellow wire that is open on the stalk side.

Can you please draw a diagram as how the switch (with led light) works related to the yellow wire (no 3 i assume?). All i know it that the switch bridges the ground to the relay.


Thanks!

This is how I interpret the way the modified install kit works. Please tell me if I got it right:

1) I install the Toyota factory Fog Light relay in the D46 slot on the top right of the Relay block, and a 15 amp fuse in position 12.

2) I disassemble the wiring harness and wire one side of the switch to D4 pin 3 (Yellow wire into the Headlight switch connector)

3) I wire the other side of the switch to D4 pin 4 (Orange wire). This takes the place of the fancy headlight switch and grounds the coil side of the relay through the dimmer switch.

4) I wire the illumination from the switch to the green wire in the console (Instrument lights).

5) I attach the hot wire from the fog lights to either pin 1 or 2 of B13 in the engine room fuse box.

6) I connect the ground wires from the switch harness and the Foglight harness to ground.

6) Did I miss anything?

That's correct and all of it.

I installed a set on my 09 as above, except I didn't like the included switch or the console location for it, so I installed an LED lighted rocker switch next to the dimmer rheostat. I grabbed the illumination feed right off of the rheostat output (Brown wire in Pin 5 is +, Green wire in pin 2 is -).

Thanks for the feedback. I ordered a relay and 09 bezels. (I hand carved the old ones but am not happy with the results. It isn't easy to carve a good elipse.) I will let you know how it comes out.

OK. I am not sure about part numbers for aftermarket fog light switches, but you may have to make some wiring changes to support a two light switch. When I installed my MicroImage fogs, I used the OEM wiring method and then installed my own lighted switch:
