Sorry, this has to be done inside the nacelle.the way *I* would do this is:1. remove the speedometer assembly2. modify the wiring between the connector and the display unit.specifically:cut the black with white stripe wire, connect anode side of diode to connector side of wire, connect cathode side of diode to display wire.cut the black with green stripe wire, connect the anode side of diode number 2 to connector side of wire.cut the black wire. reconnect the black wire along with the remaining black with green wire end.reinstall the speedometer, and, you should be good to go !
I got the same kit from a different manufacturer. I am waiting to learn to solder before installing this. Mine came with written instructions and will post it here later today.
Thanks Gremlin, Which is the Anode side and which is the Cathode side?. I am assuming one is probably longer than the other. Do I need 2 of these Diode Units?. I only ordered ONE. Damn I knew this was not going to be easy
.......................I'm not sure why all of this should be necessary because all that is really being done is to have the incandescent light bulbs replaced with a much lower wattage LED bulb................
Hmm... time for me to break out the old schematic.
this is how the factory wired it up ......
