Step 1- The connection cable from the de Garmin GPS12XL to power supply

You can buy these cables in the shop, or on the internet (see links). With a little bit of patience itīs nice to make this cable yourself.

The housing of the GPS12XL has been made of plastic (ABS?) just a few materials will stick on. You can use this point.

1. Take a cotton bud, and put some paste on the contactpoints and the walls of the Garming-connector side. This paste should not interfere with ABS and should be cleaned with water. Example of a good paste is silicone-grease, or toothpaste (which I used).
2. Take a plastic bag (sandwich bag) and push it well into the opening, so the pins will pierce through the plastic bag. Now the wall of the GPS-unit is protected against sticky materials.
3. Put on the four pins a connector ment for circuits-boards. Solder the wires to the connectors. (real dimensions approx. 15*2mm)
4. Take an empty case of a 25-pole D-connector and drill a hole in it with the size of the connectorhole in the GPS
5. Put one half of the D-connector case (the one whith the hole) on the GPS-unit and fill everything well with a 2-component paste. You can obtain this paste in a hobby-market.
6. Put the screws on the second half of the D-connector and let it all become hard.

The result you get, will look like this:

Now you have to connect the new connector with the DB9- connector, according to the table below.

Note: Use shielded cables only. Connect one side of the DB9-connector with pin 5 (Ground) and the case of the connector. This is to reduce the chance of (electrical) disturbances caused by the motorbike.
