Wiring up a set of spotlights or an led light bar has traditionally been a nightmare
and it's something that many people traditionally shy away from but i'm going to show you just how
easy it is to wire up your new led driving lights or light bar using an Adventure King's plug and
play smart harness in fact it's so easy that there is no cutting and there is no soldering required
all you need is your new driving lights or your light bar the Adventure King's plug and
play smart harness you need a couple of spanners to undo your battery terminals
some cable ties to neaten up the wiring at the end and if you've got a bit of electrical tape
and a wire coat hanger well i'll show you a great trick that you'll absolutely love
if you need to skip ahead here are the starting points for specific sections of this video
first we'll talk about the plug and play harness and what each component of it does then we'll
start by mounting the harness in your engine bay next we'll connect the harness to your headlights
after that we'll run the cables down to your spot lights or your light bar then it's a case
of running the switch into the dash and finally we'll do a light check and finish off the install
first let me go through what's in the box and what every component does now when you first open the
box it might look a bit daunting but bear with me because once we delve into it it's very easy to
understand in the box you'll have this main bundle of wiring that's cable tied together this smaller
bundle of wiring these two nearly identical pieces here and one of these black boxes with a metal tab
called relays with 24v marked on it undo the cable ties off the main harness and lay it out like this
you can see the very top of the harness has this relay and the relay holder now the relay that's
fitted to the harness when it comes out of the box has a 14 vdc marking on it that means that
it runs on 12 volt systems for most cars and 4 wheel drives utes vans that sort of thing
the only time you will need this other relay is if you're installing it into a 24 volt
truck or machinery but for most of us we can put that aside we won't need it
so next what we've got here is our positive and negative power cable so they go directly
to your battery if you follow the red cabling down you'll see there's an inline fuse holding
now of course because we're working on electrical cabling we need to remove the fuse and set it
aside somewhere safe until we're ready to install it again right at the end and just as a bit of
an aside if you ever do need to replace that fuse every car part store or most service stations have
replacement ones however that's a 25 amp fuse and it must be replaced with an identical 25 amp fuse
next we've got the wiring that goes down to the in-dash switch now we've designed this harness
to ensure that your driving lights or light bar remain completely legal when this is installed
and for that to happen a couple of things must happen first of all your light bar or your driving
lights have to only be able to be turned on with your high beam stalk and cancelled when you turn
your high beams off but as well they need to be able to be separately switched so that even if
you have your high beams on you can still turn them off and just use your normal high beams
and for that in a moment we're going to run this switch wiring into the dash
so the next length of cabling is this one here with the white t-shaped plug it connects
to one of those two supplied headlight piggyback adapters that plug into the back of your headlight
and this final length of wiring that goes down to the grey plug with the orange seal on it
that goes to your spotlights or to your light bar if you're just running a light bar then it
goes directly into that if you're running a set of spotlights you use the included two-way splitter
to plug into both lights see i told you there's nothing to it installing this wiring harness is
no more difficult than putting an awning on your roof rack okay let's get into it
so the first thing we're going to do is mount the relay into the engine bay a couple of things you
want to do here first of all is mount it as close to the battery as possible that's because you need
to run these cables to the positive and negative of the battery and they're only relatively short
so you need to mount it quite close to the battery the second thing we're going to do is make sure
that when we install it there's plenty of room for this wiring to drop away underneath what you don't
want is this wiring to come out at an acute angle because in a worst case scenario you can actually
pull the wiring out the back of the relay holder so ideally what you want is somewhere you can
mount the relay it has about three or four inches of room underneath it for the wiring to fall away
before it starts to curve okay so now double check that you have removed that fuse from the fuse
holder and we can connect the positive and the negative to the battery one of the big benefits of
these forked terminals is that you don't actually have to remove the bolt the whole way you can just
undo it just slip it in tighten it back up now the next step is to connect that white t-shaped plug
to one of the two supplied headlight adapters in the box you get two of the most common headlight
adapters to suit the most common types of headlight bulbs so connect those two white t-plugs
together and push them in place until they firmly click in then you're left with these two black
plugs unplug one of your headlights and these are going to run in between so you connect that
into the plug you just removed and that goes into the back of the headlight globe let's get into it
how you do this may vary depending on vehicle model but you'll likely need to remove a dust
cover like this gently but firmly wiggle the connector off the back of the headlight
and connect the piggyback adapter to the back of the headlight and to the plug you just removed
now neatly feed this white t-plug down through your engine bay to the headlight
so you can connect it to the corresponding white plug on the end of the piggyback adapter
take your time to tuck it all away neatly so it doesn't hang loose
push the two white connectors together until they click into place but don't cable
tie or tape it into position just yet we'll neaten up all the wiring together at the end
so the next step is going to take this grey plug with the orange seal i'm going to run
it down to connect to the light bar or to the spotlights now do yourself a favour at this stage
take a moment to make access down to the lights as easy as possible often that might mean removing
the grille but in this case what i'm going to do is just pop out these plastic clips
remove this top access cover so take a moment and have a look at the best way to run the wiring down
through past the radiator support panel you typically find there's usually some sort of
access hole often where the air conditioning pipes run out through the front of the engine bay there
just make sure that you keep the wiring away from any sort of engine fans
so if you're installing a light bar then this goes straight into the back of the light bar plug but
if you're installing spot lights then you use that included two-way splitter push the connector into
the light until it clicks firmly into place leave the grille or the access panel off for the moment
how easy is that we are cruising through this installation now all that's left to do is put
the switch into the dash now this is a tiny little bit fiddly but as i mentioned before i've got a
trick that can help here so what you need just a little bit of tape and a wire coat hanger let
me show you how to do it so we're going to take these three wires off the back of the switch then
what we're going to do is we're going to tape the wires to the end of that straightened out
coat hanger and that way we've got a perfect tool to help run through the grommet on the firewall
so before you do that here's a great little trick take a couple of photos on your phone
of how each of these three wires sit in relation to each other and also to which end of the switch
the led light is on that way when it comes time to put them back on super easy to figure out
which wires go to which terminals and a word of warning here when you're wheeling these wires
off the back of these terminals don't pull them by the wire because you can risk pulling the wire out
the back of the connector grab them around the metal connector just give them a little wiggle
and they'll pop straight off grab your wire coat hanger and untwist it then use your tape to firmly
tape the ends of the three wires to the end of the coat hanger like this wrap the tape firmly
up the coat hanger and the wiring about six inches so the wiring can't come free now you've got the
perfect tool to feed the wiring through your firewall locate a rubber grommet that factory
wiring passes through and feed the end of the coat hanger through it alongside the other wires
don't poke a new hole in the grommet as this risks letting water run inside your vehicle
if the engine bay gets wet it might take a bit of wiggling and a few attempts but eventually you'll
be able to find the end of the coat hanger up under the dash so i spent a little bit
of time and i've neatly run the wiring up into the centre console here now every vehicle is different
you need to decide where you want to mount your switch could be up on the dash here down the
centre console generally anywhere you can just easily access it while you're driving so look out
for one of these blanking plugs you can usually just pop them straight out with a thin bladed
screwdriver and just replace them directly with that included switch so i'm going to go ahead and
use those photos that i took earlier to make sure that i connect the correct cables to the correct
pins on the back of the switch here just one final note once you've connected them just make sure
that these little rubber insulation sheaths are firmly in place now you can return to the engine
bay and refit the fuse into the fuse holder make sure it's pushed in until it's completely snug
your lights are now fully connected and it's time to give them a test start your car turn
your lights on and hit the high beams the driving lights should turn on and off with the in-car
switch and should also cancel when you dip back to low beams so once you're all done in there
just push that switch firmly back in place and that's all the wiring done the final step just
to go through all the wiring a couple of cable ties just to neaten it all up make sure that it
can't move anywhere and how easy was that i told you it was a piece of cake an led driving light or
light bar installation can be that easy if you use an Adventure King's plug and play smart harness
