Hello and thank you for using JustAnswer.com
What I would recommend you do, is if your using the factory fog lights, but wiring it with a aftermarket harness and switch, just cut the factory connectors off for the fog lights, and hard wire them in to your after market fog light harrness.
Thanks for the response but you did not anwer my question. The car does not have fog lights but does have the wiring for them. I would like to use the factory wiring with after market light and which. is this possible and how
No it's not possible. The wiring for the fog lights goings into the IPDM, then to the BCM, then to where the factory switch would be. Since you do not have fog lights, the IPDM and BCM will not support the circuit, so you can't just put lights in. You will need to run your own wires to install after market fog lights.
If i buy the factory fog light and switch will they work with the car
Ps thanks for your help with this i know this is not related were is the best please to install an amp in the 2010 altima in thinking of attaching the amp to the back seat in the trunk have you ever seen this before.
No, factory lights and switch will not just work. It will require a new BCM. The BCM has to be able to support fog lights for them to work. What I did on my uncles truck is brought the factory fog lights, then cut the fog light harness connector, so they can plug into the factory light, and wired them seprately to a toggle switch for them to work.
what is a BCM
The BCM is the Body Control Module
It has programs to help other controls to work, such as lighting, the alarm, and the keyless entry and more.
Why does the dealer sell the fog light kit for the car if it will not work.
That is not a fog lamp kit, that is just selling you the two fog lights.
Salesmen are the worst when it comes to adding fog lights. They have no idea it's not a easy thing to do. You just can't put lights and a switch in these cars
So they tell customers it can be added, when it can't
Let me say it another way. It can be added, but it's much more expensive to have it installed
Yeah, I know about these kits. You still need to have the BCM replaced. The BCM lets say has 4 program slots. When you add fog lights, you need to get a BCM that has 5 program slots. This is misleading
how much is BCM
when you did you uncles truck did you have to run all new wiring or were you able to use park of the factory wiring which was already their?
His truck is a 05
I got a fog light harness kit, with relay and a switch and I ran my own wires
thanks for all of your help have a good weekend
This fog light setup with the BCM has been around since 2003
