Yes, it is the G3RUH mod and there is a least one site that shows you in pictures where to solder the wire as I remember. I did this about a year ago when I was first testing the software. I get great decodes from the FT-736R this way.
Use an old headphones cable with the earbuds cutoff as the wire. Then you have a plug ready to connect to your soundcard! If you have a choice use Line In rather than Mic on the computer.
Good luck!

I've tried unsuccessfully to decode using the 9600 b output of my FT-857 into a sound card.
The manual for Foxtelem refers to pulling the discriminator signal out of the Yaesu FT-736R for decoding. However, it does not suggest a point on the circuit. I'm thinking to try between Q20 and Q21 on the RX unit. perhaps a 0.1 uf cap to the collector of Q20? Has anybody else tried this?
Can't help off the top of my head, but ig you google for D-STAR on FT-736R, you will find mods that will allow true 9600 operation (D-STAR has similar requirements).
You'll just need to do the Rx side of the mods for telemetry decoding, but doing Tx as well will give you more options in the future.
