Thread: Where to pick up high-beam circuit for driving light relay

Have you already fitted headlight relays? If you have you can pick up the circuit from the relay.

When I did mine I took the headlight out , passenger side , picked up high beam wire , and spliced into that , back to relay never had a problem !!.. Jim

One of the high beam fuses.

I found a pretty good way:

I took the dash cover off and found the wire running from behind the indicator stick. It wasn't too hard to find with a multi meter.

It means that the spotlights come on whenever you operate the main beams (either flash or permanent on the light stick).

Hi,

Just make sure you put a switch and a fuse (probably 1 amp would do) in the line from your pick-up point to the relay.

It is a legal requirement to have the switch.

I picked up the high-beam feed from the existing driving lights, it is unfortunately tapped into the headlight loom at the back of the left-hand headlamp. I consider this a dodgy way to get a high-beam switching feed, sadly every accessory that the original owner of this vehicle had fitted was done in a dodgy fashion. At least the wire was soldered into the loom and not done with a scotch clip. I've shifted the existing lights to the roof and added a pair of bull lights that have been in my shed for years, had to do it in a big hurry in preparation for an outback trip. Would have preferred to find the feed behind the dash but will have to tidy it up properly at a later date, including using one of the original switch locations. Might use the rear fog light switch, sure as heck never gets used for anything else, will have to alter the wiring so it is only powered on high beam.

I did mine behind the headlight (blue/red from memory is high beam). Went this way rather than spicing into the dash loom as this minimises the wires going through the firewall doing the same thing and imo makes trouble shooting easier ( no additional fuses to hide etc). It is faster and easier to remove a headlight than the dash and keeps all the additional wiring as short as possible. You can get female h4 sockets if want to be able to easily remove it (ie not cut any wires).

Behind a headlight is the easiest to get at both to install and repeir if ever needed to. And do a proper job, no bloody hillbilly wiretaps!! Use a small oring pick to unclip the fitting from the headlight plug and solder the takeoff onto it. That way you reduce moisture wicking along the cable and causing problems later.
