Does anyone know if there are any points on the firewall of the 2017/18 Santa Fe where a cable can be passed through between the engine bay and the cabin? I want to fit a CB radio aerial from the nudge bar through to the radio.

I am from 'downunder ' so I've assumed that for LHD vehicles the situation is a mirror image of what I do on my own vehicle... So for a LHD vehicle, dislodge the RHS door seal rubber beside the passenger seat, remove the door sill trim and the kick panel. Depending on where you want to route the coax cable, you can undo 4 screws and drop the glove compartment assembly to give better access.....Put a jack under the kerbside front and remove the front wheel. CHOCK THE VEHICLE SAFELY ON AXLE STANDS. Remove the covers in the wheel well and find the main vehicle harness. You can poke a wire through the large grommet hole through the front door jam and into the cabin. Then run your coax cable wherever...

ALTERNATIVELY:
I installed a 600mm 6dB antenna with a magnetic mount onto a 3mm steel plate (75mm x 75mm or 3"x 3") plate attached to the roof bar and ran the coax into the door rubber, down to the floor, under the floor mats and into the cubby between the front seats where the radio lives. There is more than sufficient 'give' in the generous sized rubber door seal to withstand the 'crush' on the cable when the door closes. I have a UHF radio (GME) with all controls on the microphone. When not in use the whole thing fits snugly in the cubby out of sight.
While there can be clearance issues with the 6dB antenna in "shopping mall" carparks (!! only happened ONCE!)... Generally I have a made do with a 'mini' antenna on a magnetic mount which is approx 100mm (4") tall unless I'm headed bush on a trip. Even the mini antenna is ok for communicating with "road trains" in the outback.
I found that a roof height mount offers superior reception to the nudge bar which suffers from shielding by the bulk of the vehicle. hope this helps...
Good luck!

I'm also from "down Under" so I'm assuming that you did all that on the passenger side.

G'day Boots!
Yes ..passenger's side. I contacted Hyundai Australia to find out how to install the cabling for some driving lights on a nudge bar. They kindly sent me the instructions for cabling the integrated L.E.D. light bar in the "Hyundai "Black Ace" nudge bar (Part Number S1A85APH00). The instructions route the cabling through the front LH ( passenger) door grommet beside the main vehicle harness, into the cabin, up behind the glove box and across to the steering column trim. The directions also contain a template for cutting a small hole in the steering column trim to accommodate the relay switch. If you want the directions, I can email them to you :- )
cheers.

That would be good if you could - email is [email protected]

Hi LHthread,
I’m interested in your post with instructions supplied by Hyundai with wiring details through firewall,would you be so kind to share diagram details to help me wire up my light bar.
This would be a great help as I can find any easy way to do this.

On the 2013-2018 models you can easily wire up a light bar without a separate switch in the cabin. I did this on my previous DM model. The overall approach is to wire the light bar to the battery through a relay which is activated by a feed from the high beam circuit. Each time the high beam is on the light bar is illuminated. To prevent this a switch is normally mounted in the cabin to enable the light bar to be used "at will"so to speak.
Instead of a cabin switch, I tapped the fog light circuit to power a second relay to power the light bar relay. Thus, when you want to switch on the light bar, you turn on the high beam as usual, and then activate the fog lights. This activates the second relay which powers the light bar relay and then you have high beam, light bar and fogs all switched on!

Above the engine bay, on the LHS (passenger side in Aus.) there's an access hatch to the windscreen wiper mechanism. You can screw the relays to the back of the hatch cover and house them in the windscreen wiper void. Make a cut-out on the bottom edge of the cover to allow space for the wires (suitably taped together) to be fed into the engine bay.
I used Narva "easy tap" wire connectors to tap the respective high beam and fog light wire feeds on the LHS.
NOT SHOWN ON THE CIRCUIT IS A 25 AMP FUSE HOLDER BETWEEN THE POSITIVE TERMINAL OF THE BATTERY AND
TERMINAL #30 OF RELAY 1

The factory harness to fog lights is a blue wire and a black wire
"Splice" represents where I used the Narva "easy tap" which I wound with a silicone self annealing tape (?Rescue tape) afterwards to stop them coming loose from vibration ("belt and braces"approach!). There no problems thereafter including 1000km on heavily corrugated outback roads.
The high beam lights have a G(green) and Black with a white stripe (B/W)
I bought 25 amp wire from Jaycar for the battery to relay to light bar and light bar to earth connections. The rest of it was light gauge multicore 8 amp automotive cable from Repco/Autobarn. The relays were Narva
diode protected.
MAKE SURE YOU DISCONNECT THE POSITIVE AND NEGATIVE TERMINALS FROM THE BATTERY BEFORE YOU START THE INSTALL. REMOVE THE FUSE FROM THE 25 AMP FUSE HOLDER BEFORE INSTALL.

A sequel to the above, when I got the Dec 2019 model (TM.2) 8sp diesel, I was going to repeat the above.... no such luck! The headlight fittings are very different requiring me to remove the front bumper assembly and "tap" the (8 pin) multi-plug to the headlight assembly to find the high beam wire. This I did with a home made LED probe (see YouTube vids on how to make one of these very handy gadgets!) I then had to mount a switch in the cabin as mentioned a couple of posts ago. I still believe the utilisation of the fog and high-beam switches without adding a cabin switch is a more "elegant" solution!;)
