I got just the thing for your relays. You can get 5 relays and all relays and the relay coils are fuse protected. It comes fully wired with different color wire leads. It's also more water proof than the stock fuse box. Best part is they are only $105 with relays and fuses included shipped and comes in 3 different wiring configurations. Your over have that cost if you just went out and bought the standard relays and harness and fuses and holders. WagonGear
sells them, at the bottom of the page "Universal Auxiliary Relay Box". Here
is a thread post with a detailed description of them and the configurations are on post #11.
Config A: In this configuration, the relays are turned on by switching the relay control wire to ground. This is the simplest configuration. There is no need to locate and tap into any vehicle wires for this configuration. However, if you wish to use switches with indicator LEDs in them, or if you wish for the relays to be disabled when the ignition switch is off, you should consider Config B or C.
Config B: In this configuration, the top three relays are switched on by 12 Volts that comes from the battery or ignition. The obvious advantage for an ignition activated/de-activated relay is that you won't run your battery dead if you accidentally leave something on. Any switches with an LED indicator will require this option. The bottom two relays are configured with switched ground just like all the relays in Config A.
Config C: All the relays in this configuration are 12 Volt switched. For Config B and C, I provide a 15 amp fused non-switched wire coming out of the relay module that you can use as a 12 volt source for the switches or whatever else you would like.
There is also another way. Check in your stock fuse box. You most likely have a few empty relay spots and fuse spots. Not sure if other year TJ's have it but my 03 non-Rubicon still has an empty slot for the extra relays for the lockers. I picked up an extra relay block from the junk yard that will fit in the empty slot that takes 4 of the narrow relays. I'm going to use that to run my off-road lights, rock lights, compressor, and whatever else I might add. Won't be easy but will look stock and I don't have to find any extra room.
