Fitting is easy, shouldnt take more than an hour tops.
I'll try and do a bullit point guide to help u along
The main unit needs to be placed underneath the numberplate, so u can screw the holding bracket into the bumper itself
The unit needs to be angled so it is 100% level to the ground, so it's
useful to park the car on a level ground, and line up the unit so its
true.
U will need to yank out the R32's lower black meshing's to get the unit
mounted so it doesnt stick out too far.. sorry should have said that 2 lines earlier! They are
only clipped in place with lots of metal clips. Becareful
not to loose the clips as they are very fiddley.
Run the power cable alongside the bonnet release cable, which goes
along the grille, then up along the engine bay, then underneath the
windscreen scuttle. Use Zip ties to make everything nice and tidy.
U need to take off the windscreen scuttle panel - Need to undo
both wiper arms completely - each one is held on by one nut under the
black caps.
The arms themselves might be quite tricky to pull off, depending how
rusted on they are. Take ur time, use some penetrating oil to
free the arm from the shaft. It will come off, it's just a
matter of patience..
Now u need to run the cable into the cabin. U will need to prod a
screwdriver threw one of the rubber grommets on the firewall.
This will allow u to feed the powercable into the cabin and directly
under the dashboard to the right of the steering wheel area.
Get inside the car and u will need to remove the lower dashboard panels from around the steering wheel.
To do this, take off the dashboard end plastic (the one where the fuse
box cover is). Yank it off, it's tight, but it's only clipped in.
Then u need to undo the two large lower panels under the steering
wheel. These are screwed in by about 3 or 4 torx screws (go buy a
torx screwdriver set!) Also an electric screwdriver is so much
more useful to have to hand now!
Basically remove all the lower dash area under the steering
wheel, enough to allow u to see the whole u've just made, and so
that u can reach up and pull the power cable through.
Now it's time to wire up your switch, led and buzzer.
Where u put the power switch is up to u. I suggest u put it
somewhere out of sight, but somewhere where u reach it quickly if u
need to switch it off....
The buzzer can stay under the dash out of sight, as they are normally very loud indeed.
U can take power supply from the relay section under the steering
column. If my memory serves me well, there are 3 to which u
can undo the nuts and take one of each:
Power
Earth
Ignition
All will be obvious when u get down and have a look.
Once it's all wired up, fit everything back the way it came off.
Note:
Use some rubber sealent (or bathroom silicon sealent) around the
grommet where u pushed the power cable through the engine bay to cabin.
This will prevent dampness reaching inside the car..
Refit the scuttle and wiper arms, paying attention to fitting the
wipers back at the same 'rest' position. It might be handy to
have made a marker point by using some masking tape along the
wiperblade edge on the windscreen..
Hope that all makes some sense!
