Thumbs up wanting to replace fog light bulbs on 2010 jk

ok so i read all the forums and finally figured out what bulb i need its the H16 and i finally got it. Now here is my problem..... the bulb fits the housing but the harness adapter on the other hand is a lil to big. Now i understand the new 2010 has 24w jap bulbs (witch Suck ) now i want HID in there and like i said the new bulbs fit perfect. So what to do about the harness ????? I was thinking of cliping both ends and hard wiring them in. Dose anyone belive this will cause a problem? the gauge wire from stock harness to new one is not much different so im curios if it could hold the load. would changing the fog light fuse to a bigger amp perhaps help make sure nuttin goes wron ( wire Melt ) Thanks in advance for the help

The Ballast for my HID are rated at a 18 to 22 w constiant output power. so tech if the new psx24w bulbs run at 24w than hardwireing into the harness should be fine yes ? cause if the ballest omits 18 - 22 w than 24 going in should be no issue .. im thinking please someone with a lil more knowlege of electric componets help me out with a lil info

If the wattage for the new system is similar to the old system then there shouldn't be a need for any fancy wiring. Putting in a larger fuse is always a no-no especially if the fuse size was determined by the manufacturer. They do this considering the draw and some room for additional load. Increasing the size of the fuse may allow too much current to flow and, over time cause overheating. If a larger fuse is needed because the fuse keeps blowing in the case of headlights or fog lights then put in a relay and put the coil on the circuit that used to supply the lights and wire the contacts of the relay in a switching configuration directly to the battery and then to the lights. The wiring to the battery should be sufficient to carry the load of the lights as well as the contacts of the relay and should be fused appropriately. Remember, the aim is to produce the desired effect without causing a fire in the vehicle.

I wouldn't oversize on anything on the JK as everything seems to go through the computer. I would rewire with a relay unless someone here has tried it with success.

Use the stock wiring to trip a relay; use the correct connectors to your rebased HID capsule and connect them to the hot lead from your relay --- which will be powered via fused link from your battery. Use 12 gauge stranded wire.
Although HIDs have a relatively low power draw, they have a very high amperage draw at ignition and will degrade stock wiring.

Do not ever run your HIDs with oncoming traffic; they are not intended for those reflectors and will blind other drivers.
I'm assuming that you realize they're illegal for street use, right?

Of course we'd like to know what you did.
