Under dash UHF radio install

[AnD3rew]

If you take off the trim, you can see there is a control box mounted under the steering wheel.this is held in place by a steel bracket that has cut outs to reduce weight. I just cut a small plate that covered some of the cutouts allowing me to screw the radio bracket to that plate through the cut out areas. You could maybe use big washers to bridge the cut outs and bolt through them if you weren't confident with making a plate.

Ahh, I get it now. Thank you, thats simple, yes could use a nut and bolt and a washer, I see. Excellent

This is a short description of my install of my UHF radio under my steering wheel with the antenna (temporarily) attached to the grab rails. I'm still waiting for my roof rack. My vehicle is RHD with aux power. I used the grommet for my power outlets, under the grab bars. Removed the grab bar and fed the antenna through the grommet, along the roof inside, you'll see where to go once you take the grab bar off. Along the roof down the b pillar. Need to make sure you go behind the curtain airbag above the passenger door or you'll have a problem if you need it... To remove the B pillar trim, start at the bottom, remove the front door and rear door sill trim. Unscrew the bolts and lift the bottom piece off. There are two screws at the bottom of the next piece of trim which need to be removed and the top piece just clips in. You need a trim removal tool and be gentle. I have the removable hose out floor so lifted that in the front and rear. Once I got the cable to the ground, went under the middle of the chair as it was too tight where the wiring loom was. From there along rhs wiring loom on the floor on the RHS. I used the drivers side footwell power and the unit is a concealed one under my steering wheel behind the dash trim. Hardest part was getting the cable under the seat takes a bit of juggling... Sorry I didn't take pictures of the b pillar routing.

Did you remove the roof lining or was it easy enough to feed through to the b pillar once you removed the grab handle?

No need to remove roof liner. Can gain enough access by dropping door seal. Careful not to interfere with air bag. B pillar plastics will need to be removed. Use same rubber grommet as power outlet if you have this feature.

Hi All
I'm trying to run a UFH radio antenna cable from my roof down via the b pillar into the cabin. Having searched the forum this seems to have been done by others but I'm missing some details on routing the cable into the b pillar. Where does it need to be routed to get down the interior of the b pillar? I'm assuming the idea is to have the cable emerge from the pillar in the hole circled in yellow in the photo. I've seen some reference to dropping the door seal to assist in routing the cable but this isn't clear to me.

I could see a more straightforward route in through the big hole (number 3) then down under the roof liner to the door seal along the orange dotted route then run the cable between the pillar and the trim where the seatbelt goes. But this seems to conflict with the airbag above the rear passenger seat.

Any advice appreciated.

Just found this post. Similar situation.I removed the tie down roof bar and composite panel and chose the large hole #2 from where I could see inside through the attachment point for the cargo barrier. I actually used a step drill to make a 8-10mm hole in the composite panel and inserted a gromet which was sealed in place with liquid insulating tape "goo" to feed in the coax. rather than through the existing electrical box. I noted the airbag is wrapped in a tube like arrangement similar to a roller blind. I passed the cable behind the airbag...i.e. between it and the external wall of the B pillar, fixing the cable to the the wall with a patch of Gorilla tape so that it will not impede the action of the airbag. I then fed the cable behind the B pillar trim to exit at the base. I plan to access the centre console cubby and mount the UHF radio (GME 330C) in there with the handset, and use the 12v power outlet already in place. Just need to find a suitable position to drill a small hole in the cubby to feed in the coax. from behind the outer trim panel....

Update on the above

because of clearance constraints from the garage door, the antenna is positioned to hinge across the roof instead of parallel with the rain gutter. Note antenna cable penetrates the roof cover through a tight fitting sealed grommet behind the tie down bar
