Try this out, fairly confident you shouldnt fry anything.
56a and 56b connect to brown and green wires that go to headlights, they are for low and high beam
56 is from the headlight switch - dont remember what colour it is. Turn the headlight switch on and see which wire gets 12V, possibly light blue.
31b should be the white?(or black) wire that earths the relay via the indicator stalk, can test by seeing if the wire connects to earth when the stalk is pulled back.
15 is from the ignition. No memory on what colour it should be, turn ign on it should have 12V on it, or be the only wire left to connect.
If high beam indicator comes on with low beam, swap green and brown terminals, cant remember who is a and b.
Let us know how you go.

The Devil and I worked this out once before on the old forum.
The problem is one book shows the colour connections (Gregory's).
The other shows the relay terminal relationship but no numbers or colours (Max Ellery's).
But no book shows colour vs terminal number.
White to term 31 ------dimmer switch
Pink to term 15 -------power from fuse box
light blue to term56 ------Power feed from light switch in dash.
light green 56a ------high beam
light blue to term 56b ----low beam
I suggest those with LX's record this information as it's a bitch to find. I suggest you mark up a diagram in a manual. I have.
P.S. If you cut any wire apart from the red one, it will explode.

typo.....56b ought to be light brown.
'dipper' not 'dimmer'

It has been a long day in the hot sun painting the x member and stuff.
Found this great stuff that contains 98% zink and is a satin black. Looks very original with the benefit of corrosion protection.

Just a point I made that is perhaps superfluous. Connection of 56a and 56b to either green or brown wont matter in terms of operation of the high beam indicator as the indicator would have to be connected to the actual high beam wires.
It does matter though that high beam is connected to 56a though in terms of the flasher, as it is high beam that is meant to be flashed.

White = 31b (bottom right corner)
Pink = 15 (centre horizontal)
Blue = 56 top (left corner)
Green = 56a (bottom left corner)
Brown = 56b (centre vertical)

Low current 12v supply = Pink = 15 (centre horizontal)
High current/light switch 12v supply = Blue = 56 top (left corner)
High beam = Green = 56a (bottom left corner)
Low beam = Brown = 56b (centre vertical)

If no one on the forum wants to offload one it sounds like a plan.
I have also sent a message to bosch - be interesting to see if they still have anything - or equivalent

Hi all. An old thread but thought best for continuity. I can't seem to find my headlight relay for LX and found one on EBay. Unfortunately I can't copy the link (can someone direct me to where/how to) but it looks exactly as per pics and diagrams provided above (seller Prestige Auto part listed as: genuine Bosch step-by-step relay 0332515009). Only thing that has thrown me off is that when I check the compatibility list LX torana doesn't satisfy but this maybe just because they don't know. I realise the LX relay is different due to the hi/low beam on the indicator arm so any thoughts would be appreciated. Cheers Ron

Thanks Brad. That was my thought. I'll keep digging around for my original one but may be an option if need be. Cheers Ron

Yes just put the part number into ebay - heaps of choices. The one that I got (that works fine) did not have Torana listed either. Figuring that their list of cars did not go back that far..

Thanks Mike. Issue is the cost if they aren't right, but regardless of whether or not I find the original I am contemplating buying a new one. Cheers Ron

Hi all .... not sure if my high beam is working or not ... well the dimmer does not seem to be.
Recently had some work done to tidy up under the bonnet and in the process the painter ommitted to re-connect the blinkers which I found out straight away when driving it home. But recently about 8 months after having the under bonnet work doen had the need to drive it home in the dark after a wedding and low and behold the headlgihts did not work. Had to drive home with my hand on the blinker switch holding the high beam on.
Anyway, next day while checking the relay noticed one of the wires was off so put it on ... did not seem to fix the lights. Mucked about a bit, got the parkers working and now have either high or low beam working but when I flip the dimmer nothing happens.
Pretty sure I have the wires on correctly but can someone please confirm (second pic).
If they are on right ... what is my next step to get the dimmer working!
First pic is an amalgamation of the pics in the thread above .... I needed to put a few tpgether so i could work out the wiring all in one pic
The second pic is my current relay set up.
