I have 1998 Accord Sedan and I'm trying to put in fog light in the front.
But how do I do the wiring for it?
Please help me as soon as an expert read this!! Please!

 

just crimp the wire to a switch then connect that to the hot wire which connects to the parking lights, some internet sites have the wire colors, and connect the ground to some nut by the steering column. or u can just connect it to a switch then directly to your "daylight" headlights fuse, and that is much easier, no crimping nothing, just wrap the wire around the fuse. and ground it.

 

By law in most areas if you install fog lamps you must your interlock your fog lamps so they cannot be on at the same time as your hi beams. For obvious safety reasons. Ignorance of the law will not save you from a ticket either.
I looked thru a manual for a 98 Accord and the wiring diagrams show a schematic for the headlight system. It also shows fusing, relays, switches, and interlock cctry for your fog lamps as well. If your car didn't come with fog lamps then I bet the fuses and relays needed didn't come with your car, however, the wiring and relay bases and maybe the switches DID come with your car. The reason being that any car maker can add or take away accessories from a standard design that has provision for options. So they build in for options. Standard wiring harnesses, standard electrical fuse panels, standard relay enclosures. Standard fuse enclosures. You get the idea. This is also a cheaper way to build a car.
To you this means that all the work and base components may already exist for your fog lamps.
All of your base control wiring probably already exists in your car. You have just never used it. You may just have to buy and 'plug in" a factory Honda relay or 2 for your fog lamp cct. These relays being plugged into existing Honda receptcles wired to standard harnesses. The headlight switch on the steering column shows a seperate contact for the fog light cct. This contact is probably in your "existing" headlight switch on your steering column and is wired to somewhere under the dash thru a standard harness. What's the cost of an extra contact when you make a million units? The location of the fuse for your fog lamps is unclear in this manual though but I'll bet you can find a prewired spare fuse location somewhere else.
Buy a manual and read. Everything may alreday be there.
