I'm useless with electronics.
I built an adapter yesterday. This time, I thought I'd try the "cheap headphones" route.
I soldered my power wire to pin #1.
I soldered one headphone wire to pin #4, and the other headphone wire to #5.
I took the dash apart -- again. I crimped a connector on the end of the adapter power wire, and used another wire, also with a crimped-on connector, to pull off the 12V power in the dash. I ran both wires through a swith.
So, I plug the adapter into the back of my headunit. I turn the key to activate power. I turn the headunit on. I throw the switch, and . . .
AUX comes up! Huzzah! It works! Fucking A!
I immediately plug the power wire, antenna wire and now the headphone plug into my satellite radio.
Nothing. No sound.
I turn the volume to max. Nothing.
Fuck.
Well, I'm getting there. I know it works. I wired power through a switch without frying my headunit.
Shit. Maybe I better just order the part from Mouser . . .
