Hi all,
This guide won't be relevant to corolla owners with foglights (sportivo/levin owners and prewired corollas).
I've found an easy way to install OEM foglights to my corolla which was NOT prewired for foglights.
I basically added the missing foglight wiring in the engine compartment and connect it to the foglight wiring present in the cabin.
This works with the sportivo/levin headlight dimmer stalk with foglight switch.
THIS IS A GUIDE ONLY I AM NOT RESPONSIBLE FOR ANY ISSUES THAT MAY ARISE FROM THIS.
materials:
*headlight dimmer with foglight switch
*OEM foglights
*15A auto fuse blade type (this might already be in the car)
*narva micro relay 68062BL
*custom made foglight harness with appropriate plugs (H11 female plugs for facelift zze corolla) below is a diagram of one. parts can be bought on ebay to make one
Method:
First remove the negative battery terminal.
install the foglights and foglight harness by removing the front bumper. Below is how I routed the wiring:
ground the negative to the chassis and route the positive through the firewall into the cabin.
in the cabin remove the glovebox to access the fuse box. install/check that a 15A fuse is in the "FR FOG" slot:
in the driver side remove the mini storage box to access the relay block. plug in the micro relay in the middle slot:
route the +ve wire from the firewall, the driver side and behind the foglight relay block. from behind the relay block there are 4 wires plugged to the relay, tap the +ve wire to the RED wire:
Finally install the headlight dimmer stalk. No need to remove the steering wheel, just remove the steering column cover (3 screws).
reinstall the negative battery terminal and you're DONE!
Area for improvement:
I tried to find where the red wire (from the relay) terminates in the engine compartment but had no luck. That would ease installation and save on wiring.
I hope this was useful
