Making a voltage line inducer for DreamPi: doubt

[pustal]

I've soldered a line inducer but wanted to make sure I'm doing everything right and test everything. Most guides I find are incomplete at best. The best one I found was this one that at least indicates the direction the inducer should be connected.

Here's my doubt however: all guides point the red line as the line to induce the voltage and given that the cable is unidirectional I take it matters which end of the cable is on the left side of the diagram as JR11 cables are crossed:

In one end the red cable is in position 3 (or 2 in a 4 line cable), and in the other, it is on position 4 (or 3)

I soldered according to what seems to be the convention, the left side of the diagram corresponding to position 3 and the right side to position 4. I however find no confirmation anywhere that my assumption is right and am afraid to test it and fry something on the Dreamcast modem.

Can anyone correct me or confirm me before I mess up?

What, did you solder directly to the modem?
To install your LVI you just cut into the middle of the red wire.

I know it's an old post, but still...

No, how did you read that from what I wrote?

What I'm saying is, you're modifying the wire, not the pin. It doesn't matter whether it's in 3 or 4 position; a red wire is a red wire.
If you actually meant the rotation of the cable... RJ11 cords physically can't do that, they go in one way only.
