OK here goes,
First of all buy yourself an Omex Shift Light ‘Sequential’ It’s the one with 4 LEDs in a nice easy to fit self contained block, Should cost around �135, you can also buy them from Demon Tweaks. There is also a Shift light Pro, which has one big LED, but this is designed for put through a hole and you don’t want to go drilling your Lotus.
By the way, everything you do while fitting this shift light is reversible, so you can take it off and use it on your next car, you also won’t be causing any damage.
The Shift light only has 3 wires Red (Coil Positive) Blue (Coil Negative) and Black (Earth). Then of course there is the wire that goes to the LED block.
Remove the bottom part of your steering column surround. If you then look up at your dash board at the bottom of the Stack dials, you should see a big’ish bolt on either side of the dials, this attaches the bracket which holds the Stack dials to the bulk head. Undo both of these bolts and the dials should lift up and fall forward, the wires are not very long though.
You will see at the back of the dials there is one big connector, you need to unplug this connector, mine was quite stiff (giggle), so I used a big screw driver to CAREFULLY tweak the connector off.
The connector has two rows of connectors, A and B, you should find these little letters embossed on either the connector or the back of the stack dials (I can�t remember which, but I spotted them so it can�t be that difficult.) You need to locate the wires that go into A3 and A4 connectors, simply see which end has a 1 embossed on it and then count on from there.
On the instructions I used, the colour of the wires were indicated with a G for A3 and WB for A4. Locate these wires and check that the colours are right (Please note, I can�t remember if G is for Green or Grey so don�t ask, and I really don�t want to have to remove my dials again to find out 
.
You will be mounting the main control unit inside the dash, to the right of the dials behind the light switches on the aluminum bulkhead. Cut the red and blue wires to the appropriate length between this and the A3 and A4 wires.
The wires that go into the connector block are protected by a sleeve. You will need to slit this so you can get a scotch lock onto the wires.
Scotch lock the Red Shift Light wire to A3 and the Blue to A4. Then connect the Black wire to any suitable earthing point. All aluminum and even the steel bracket can be used as earthing points.
Set up the Shift light following the instructions that come with the Shift light. Once you are happy with the settings, peel off the backing to the sticky pad on the main controller and locate it inside the bulkhead behind the light switches.
You can now re-connect the big connector to the dials.
The wire that goes to the LEDs should now be routed round the left of the dials and the LEDs should be stuck in place at the top of the dials (see picture).
Shove the excess wire into the bulkhead and refit dials and surround.
You�re done. If you don�t feel like doing it yourself let me know and i’ll fit it for the cost of a pint, providing you come to Castle Donington because that’s where I live .
Good luck.
John.
