Well the FJ40 never came from Japan with a revcounter fitted as standard, so my options were either to fit an after market VDO type gauge, that is marked to 8,000rpm and only use half the dial, or to try and source something more stock - Toyota-ish.
Now the BJ42LX did come with a nice little gauge, fitted just to the right of the gauge cluster in RHD markets, so the 1st step was to source one of these.
Via a contact on Mud we located a spare and collection was made by Keith during a business trip to Australia. Thank you Rob and Keith.
Problem is the tach in the BJ works via a magnet in the flywheel and a hall-effect sensor in the bell housing, kind of like an over grown bicycle computer. Well after receiving and testing the gauge on a friends BJ, I was in 2 minds whether to go to all the hassle to continue with the project...
Funny how ideas come to you at odd times, I am not sure what I was doing when my thoughts returned to the tach, and I remembered that my FJ60 had a small round tach in the centre of the gauge cluster, maybe it would work! After a few weeks we managed to source one locally and the project was back on track.
1st off get some snacks, can be hungry work

BJ - ignore pen, it is wrong

These pins had to be removed with the Dremel in order to rotate the circuit board.
And the case modified slightly so it would all fit in its new home.
Nearly there
All done, bar a lick of paint on surround.
Just need to test it before I cut the hole in the dash, would hate to do that if it does not work, watch this space.
