My FJs 10th birthday mod-a-thon is still going! I've done, and still have to do, a lot of cosmetic and mechanical upgrades and additions. Today's addition is auxiliary lighting in the light ports of my Expo1 front bumper (I will be putting lights in the rear one as well, and adding a roof mounted light bar later).

I'm pretty ignorant when it comes to electrical wiring and did a fair amount of research and watching how-to videos. Over the course of the day (and several trips to O'Reilly), I was able to get everything hooked up and working. However, after stumbling across this writeup and doing some more reading, I feel like I may have made a mistake somewhere.

I purchased these lights to go in the bumper.

And to use this switch in my center console button cluster thing (the 2 rows of 4 buttons under the radio)

My concerns mainly center around that push-switch. I grounded the ground wire (black), I took the red2 (red wire next to black) and plugged that into an add-a-fuse in the box under the steering wheel that provides power to the button when the key is in the ignition), then took red1 (next to green) and sent that to my Relay.

I was working off this picture

I didn't quite understand where green was supposed to go. After some vain searches and trial and error, I found that the only way for the push-switch to work properly (light up when turned on and actually turn the lights on as well) is to tie green directly into the + terminal on the car battery.

That's the part that makes me nervous now. There is no fuse or breaker between the push switch and my vehicle battery.

My other thought at the time, which makes more sense to me now, was to splice green into red1 (the one that goes to the relay, which has a fuse on the power line from the relay to the battery).

Any advice is greatly appreciated.

Red 2 is only for the lights on the switch which turn on when the ignition is on if you wired it as you say to an add a fuse to the fuse block (Assuming it's one of the ignition on fuse spots)

Green should go directly the + post on your battery. You should use and in line fuse at the recommended amp rating for the switch.

You can pick those up at O'Rielly too, it's best to solder them in, but butt connectors will work too.



So, from your diagram
GREEN = Source (From the positive battery or a HOT fuse slot on the box)
RED1= Power to your Relay (Which you wired correctly)
RED2 = power from an ignition tied fuse (To light the switch)
BLACK = to Ground

From the wire harness I received with the lights I have a direct line with a fuse built in between my battery + terminal and my relay.

CAR BATTERY --------FUSE-----------RELAY

Should I solder the green wire in between my FUSE and RELAY that goes to the battery?

CAR BATTERY ----------FUSE-------green splice------RELAY
