Just made up a twin LED boot light using 2 LED's in the scrap box (LEDs bought as sidelight conversion but weren't bright enough).
Note: This system uses the spring alarm switch next to the lock plate. My B alarm doesn't use this. If you have the old type original alarm then this conversion isn't for you...
Look at the plastic plate over the boot look. It has 4 screw holes. The outer 2 are exactly right for fitting a recessed pair of sidelight LEDs and the plate works just fine screwed with inner bolts only.
Take the plate off and make up a pair of bus bars: Parallel +/- feeds to the lamps. You need to work out the terminals on the LED's first as they only work with the power the right way around. You also need a 1k ohm resistor in series with LED (the sidelight bulb units have this built in) or the unit will quickly burn out. Be careful when doing this...LED's take small amps and are easily destroyed.
Take a + feed from the red/white wire that feeds the power aerial and a negative from the chassis. I used a spade connector clamped under the right hand lock mounting bolt. Tape the + feed off until you are ready to use it as it will certainly short circuit somewhere in the boot and blow the fuse...
Disconnect the snap plugs from the boot alarm switch next to the lock. Wire the + feed to one side of the switch, add a quick acting low amp fuse in the circuit and connect the other switch terminal to the + bus bar.
Take the negative feed and connect it to the negative bus bar. The LED’s should now light. Test that they go off when you push the boot switch...i.e. boot closed. Tape off all connections and insulate the back of the LED’s to stop them shorting against the body panels. Refit the lock plate with the inner 2 bolts and ensure the new wires are tucked down out of the way of the lock / cable.
Job done and a pair of neat, recessed lights in the boot.
I was trying to add an excel circuit diagram but apparently this forum doesn't accept it?
