You need a Land Rover discovery 1 bonnet release cable ALR7062 @ £6.99, a 100mm length of 5/8" fuel hose, a 20mm worm drive hose clip, a wire rope grip clamp (5mm) a small piece of aluminium angle about 1" x1" x11/2" and a little patience.
If the cable in the boot goes, you are in trouble so I decided to fit a bonnet pull inside the car behind the fuse box flap.
I made a bracket by drilling the aluminiumsection.
The bracket is drilled 12mm high on one face and the 8mm hole low on the other so there is clearance for the bolt when the cable is fitted and fitted it to the left hand side of the steering column mounting after removing the fusebox panel by slackening the Posidriv screw on each side about a turn then pulling it towards me.
Here is the bonnet release bolted to the column mounting on the left hand side. Simply remove the 10mm headed bolt and pass it through the 8mm hole in the bracket. The speedo cable grommet was a little perished so ideal to push the cable through,
routing it under the rearmost horn connector and the ABS loom
before parallelling it with the cable from the bootlid past the right hand headlight and onto the latch.
Remove the screws holding the slam panel to the body and the bumper and the two bolts holding the security cover which may be retained or discarded according to your choice. Clamp the two cables together as there is nothing to retain the new outer cable. To do this, take the fuel hose and slit it lengthwise before placing it over the two cables, fitting the hose clip over the middle of it
and tightening it securely.
The free end of the cable is now pushed through the loop on the end of the original cable, pulled tight and doubled back before clamping it with the cable clamp.
Reassemble with a minimum number of bolts while you test it as it will need to be stripped if anything isn't tight enough and expect that the handle will need a firm pull to release the bonnet. Once all is well, replace all the hardware.
