Many TD5 drivers already asked how to install a rev counter. In fact it's quite easy as this report by from LandiePhil at www.viermalvier.de shows. Thanks Andy for the german text and pictures.
I used a rev counter especially for the TD5 by VDO.
The counter isn't cheap but I wanted an gauge that looks exactly like the other instruments.
To fit the gauge I had to clean things up first. I removed the clock- after all I have one at the wrist. I moved the coolant and the tank gauges to the left. Now I had a free mounting space immediately beside the speedometer. After setting it in it's new place there was a new question: How to wire it up on a TD5?
The gauge has 5 contacts: 2 for the light, one to connect to a switched line with power on when contact (don't use the + from the clock here), one earth (here you can use the - from the clock) and one for the signals. This last one was wired to the ECU box under the passenger seat. On the silver box (ECU) you see 2 large connectors on the front and 2 on the rear. Use the rear black one (C0658).
The rear connector C0658 has 3 rows of connectors: Upper, middle and lower row. The sixth switch in the middle row, labeled #19 is the signal output to use.
On mine (a 2000 model) it was connected to a white/grey cable but on a 1999 model there was no cable out on the back side. In the pic below the new yellow cable is already mounted.
Now put a needle in that hole and connect a rev counter with crocodile clips to it. Start the engine and see if the rev counter works. If it does (and why shouldn't it?) make a permanent connection. If there's no cable simply inset the correct cable shoe and new cable. Else solder a cable to the white/grey line and put self-vulcanising tape around it.
It this does work with every rev counter? No idea but for us it worked with the genuine Land Rover rev counter.
