pics and explanation
I bought two items, from Tandy - a microswitch ($3) rated for 12 volts and a flashing LED ($5) set up for 12volts. The LED was designed to imitate a security system LED, so it came ready to mount with it's own wiring.
1. Remove centre console completely - this forum has details.
2. Connect 600mm wiring to microswitch (solder it) 2 wires
2. install micro switch onto a flat plate approx 70mm x 20mm
3. install flat plate as in picture labelled "microswitch" This pic show the lever in the D position, pulling it back from there immeditately activates the LED. The switch needs to be very precisely placed and I found that making the holes in the flat plate larger than I needed and using very short big headed self tappers gave me all the adjustment I needed. However - there is a hole in the lever which the actuating arm of the microswitch can drop into, so I had to put washers under one end to raise it to avoid this.
4. run one of the wires to earth - there are a couple of convenient screws when you pull down the fuse panel cover
6. Mount the flasher unit - I put mine on top of the steering column using an old Ford Headlight switch. The upper part of the cover can be removed by carefully squeezing it up MAKE SURE nothing is going to stick into the wiring below when you put it back.
7. run the red wire to the power at the fuse box.
8. connect the remiaing wire (white) to the other one from the microswitch.
It took me a bit over half a day to do it.
Couple of refinements
I did find that the raw LED was too much at night so as you can see in the pic I've put a "plate" over it (bit of interior light cover). Found that made it too faint in daylight especially when the sun was directly on it so it now has a bit of plastic tube over it to prevent direct access by the sun. I have to say, I am very pleased with the result. It works a treat.
