Total retard! (light harness help PLEASE!)

Ok, I have the Lightforce harness.
instructions are crystal clear, save for one part: brown wire goes from one side of switch to "active high beam switching wire" on the back of the headlight.
my problems.
1: how do I determine which wire is the "active high beam switching wire" ? Is it always hot? hot only when key is on? hot when key on and high beams on?
2: if it is only when key and high beams are on, does that mean my lights will only work when key, and high beams are on?
3: can I bypass that shit, and wire that side of the switch to the + side of the battery, so that if I want to use the lights, I just flip the switch?

I normally am not so retarded, I know how to solder, can use a multimeter, but this has just ruined my noggin.

For reference: https://www.jkowners.com/forum/showth...lightforce+170

With this set-up your Lightforce lights will only turn on if your brights are on. Technically, you should be able to run the wire back t the positive post for independant control ...I did it with a pair of PIAAs I used to have.

Would it be a safer bet to run it off the cig lighter(tap into the power lead of the socket)? I would assume less amps there, and as it is relay driven, it wouldn't be much of an issue. I don't want to let any magic smoke out of the harness,

Yes it would be safer to run it to an "accessory power supply"

It should be relay driven. It also "Should" have an in-line fuse.

It has at least one inline fuse, but I don't believe that there is one on the switch power wire, or the one leading to the relay. I am at work so can't check.

Ehh, worst case= I build a heavier duty harness if I smoke this one.

Does it come with a relay? If so, use the cig/aux power to actuate the relay and ground in dash, and then take power direct from the + and - for the relay to light.

Yeap. That is my current plan. Comes with a 30A relay, 30A inline fuse (+batt to relay I believe) and a 30A switch, that I am going to replace with something...cooler.

Should be a fuse for the lights. ( probably 30 amps or so ). And there should be 1 fuse for the switch ( probably 4 amps or so ). THOSE LITTLE FUSES PROTECT A LOT MORE THAN THE HARNESS!
