I put a thread up the other day asking about dual high beam didn't get a lot of help so i worked it out and thought i would post a how to.
5meters of 7x1.5 multi-core cable(As long as the multi-core has at least 4 wires it should be OK. All the cores will be of different colours)
*2 x 5A fuses and fuse holders
*2 x 4or5 pin 12v 30A relays and relay holders if you can get them
*8 x Insulated female blade crimps
*4 x Insulated lugs with 6mm hole
*4 x In line cable joiners
*Black cable ties
1. Firstly disconnect the plug from the back of the right hand side headlamp. You need to join one of the cores to the high beam wire and one to the low beam wire. You'll find there are 3 wires, one being the high beam, one being the low beam and the other the ground or negative.
2. Join the wires in a way so as there is a good connection and are as neat as possible. you run the multi-core along in front of the radiator where some of the original cables run, have a look to see and you should be able to hide it quite well. Then cable tie the cable in place.
3. The cable should then run past the left hand side head light where you put a hole in the outer sheath of the multi-core and managed to pull two cores out (this is a little bit tricky, see below for tip) so as you could join to the right hand side head light in the same way. Run the end of the cable around to the fuse box or where ever your going to mount the relays and fuses.
4. Firstly connect the two wires from the right hand side headlight to the first relay. Connect the High beam wire to terminal 86 on the relay and connect the low beam wire to terminal 87.
5. Then do exactly the same on the second relay.
6. Run two separate wires from a good ground or negative to terminal 85 on each relay.
7. Then run a hard active straight to the fuse (fuse holders), do this on both relays.
8. Then from the fuse run a wire to terminal 30 on the relay, do this on both relays.
This probably could be done using only one relay, This is just for one side so just duplicate on the other side.
Tip: Gently make a hole in the outer sheath on the multi-core cable. Try pulling two wires through the hole. Just don’t pull the two wires used on the left hand side headlamp. When pulling them through you’ll need to wiggle the cable quite a bit. you end up pulling them through a bit from the end that goes towards the fuse box then cutting them. You only need about 50mm.
