Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello. Please allow me to assist you.
Please describe the wires that you need to have hooked up...how many are there?
On most aftermarket systems, you have the following: A main power wire, a ground, a signal wire, a relay, and a switch.
The wire that goes to the switch attachs to your Low Beam power wire.
The power wire goes from the battery to the relay.
The wire from the relay goes to the switch, and back to the relay.
The power to the foglights goes from the relay to the lights
To describe the system, it runs as follows: Turning the fog light switch on, with the headlamps on, sends the power "borrowed" from the Low beam wire, and activates the fog light relay. The battery power is always present in the relay, but is doing noting until the relay is activated, via the switch. Once the relay contacts close, the battery power is then sent thru the relay contacts to the foglights. The relay is used to keep the switch from arcing when the foglights are activated.
Constant Battery power to Pin 30 of the fog light relay
Tap into the Low beam wire, then into an inline fuse (for circuit protection), then into the fog light switch, and then attach the other side of the switch to the relay, Pin 86
From the relay, Pin 87, route to both foglights.
From the relay, Ground Pin 85
On the other side of the foglight wire, ground both remaining wires that are not attached to the relay via pin 87
You took too long to answer. My brother and I installed the fog lights without incident and they work fine
I am sorry about that; I never saw your question on my screen. The only way that I was aware that you had a question posted here was via an e-mail to me; I was contacted by a Moderator from this site, who asked me if I would please assist you with your dilemma. In any case, glad to see you got it fixed up. Thanks for considering Just Answer for assistance. I am sure the next time you require assistance, the response time will be much shorter. Have a great day.
