At the risk of diverging further off topic...
If you're going to go this route, Cumulus Soaring has a slick cable to allow a Garmin GPS antenna to be powered through the ACK ELT. I have this setup in my no-electrical system J3. Works great and has an LED that blinks to show when the ELT is getting good GPS data.
The p/n is "Cable-E04-DB9m-LED-12V-0.3". Google that and it should come up. Not cheap at $75, but it was completely plug n play.

Cable, 0.3 m (11.8 inches), Cable for GPS data and 12V power for ACK E-04 ELT, By Goddard
The ACK E-04 can accept GPS data though its mini-DIN connector. It can also accept 12V power through the same connector. However, since the E-04 has no user-interface, the manual recommends using an external LED to verify that the E-04 is receiving GPS data. This cable is designed to allow the connection of GPS data and 12V power to the E-04 and it also includes a "GPS Status" LED built into the DB-9m connector. It has a female Mini-DIN connector for connection to the E-04's GPS/power connector. It also has a DB-9m connector for connection to a cable to go to a GPS. The pin connections on the DB-9m GPS connector are the same as the GPS side of a Goddard PS-5a power converter. The cable also has 12V power leads for providing power to the E-04 and also providing 12V power to pins on the DB-9m connector for powering the GPS (if necessary).
If you don't already have a GPS to connect to the E-04, the Garmin GPS 16x-HVS would work great with the E-04 and this cable. This cable would power the GPS 16x-HVS with 12V. Be sure to order the Garmin GPS 16x-HVS with a DB-9f connector.
