got a test light? just test the plug out of the back of the headlight, first with low-beams on, then highbeam. (the one that didnt light up the first time but did the second time BINGO highbeam

)

and from memory i think its the top wire of the three (but dont hold that to me)

Just checked it on my Gt Foz for you. Top terminal (Yellow/red strip)

Also run the negative wire from body, install relays with spotlight. Also install thicker wire for negative battery to body..

Hey mate, copied from one of my posts elsewhere:

When I wired in mine on my gen 1 lib, the wire colours were completely different to what the FSM said they would be, so I went about it the 'hard' way...

I presume you have a multimeter? If so then I did the following:

With lights off:
Put LH indicator ON and probe around the harness connections on the steering column - I'm pretty sure there is about 4 of them.
When you find the indicator plug (easy to tell as its voltage will be going up down up down up down) then you're on the right harness plug to find your highbeam wire.
Record the colour/location of wire for that indicator and then find the RH indicator and record wire colour/location
Turn your indicators off and turn your headlights on (low beam)

Headlights on (low beam)
Find light wire and record colour/location

Headlights on (high beam)
You should now only have one wire left, if not probe for the wire that has 12v or similar with the highbeams ON but 0v with highbeams OFF.
This should be the wire you are splicing your switch into. Legally, you need to have your spotties on a remote switch so that you can have highbeam without spotties. I connected in at the lights side of the connector just to keep the steering column clean.

Hope shed some light on your quandary!

Cheers,
Owen.

Its probably the long way about it but it hasn't proven me wrong yet after several installs.

What spotties did you get?

thanks a lot for your prompt response guys!!!
i have a full ready made wiring kit that is just almost plug and plug, with switch, relay, all wires, etc,
just needed that high beam wire, haha

got it all wired up, and it still aint work,
i wired it up as per instrustions as if it was a "positive switching headlamp system"
as opposed to a "negative swithcing headlamp system"
could this be it?
if so, it means connected one red wire to the existing red/yel high beam wire, and the black, that was earthed to the body, to the negative wire on the headlamp system?
any ideas fellas?
do i try this?
and if so, will it be connecting to the blue/white wire, the the red wire?

Subarus have everything earth (negative) switched. The red/yellow on the back of the headlight goes to one side of the spotlight relay coil (pin 85 or 86). Find a wire that has +12V when ignition is on and connect that to the other side of the relay coil. Whack a switch in one of those wires to the relay so you can turn the spots off.

Have a look in guyph's recent thread on this topic, El_Freddo posted a wiring diagram which might help.

GOD... High Beam and Low Beam wiring... infact every light on the Forester is POSITIVE switched except the interior light and dash lights. I actually went out to the car and tested this before i posted.

I think (i used the word THINK cos im not sure), the MY and L series Headlight wiring is negative triggered like u have said.

GOD no offence intended but try not to give out information thats not correct and if your guessing then let people know what your saying is a guess.

The way you have told him to wire it up would make the spotlights come on when your Ignition is On and the Highbeam is Off OR come on when the key is Off and highbeam On. Im SURE this is not the desired result he is after.

I don't know what your trade is mate but i sure as hell hope your not an auto electrician.
