Pickups, Pots, Caps, Wiring

Here's the dilemma. My '78 Maton has a built-in pickup, not sure if it's UST or Piezo, but it sounds ok (typical compressed, quacky sound). Over the summer I acquired a LR Baggs M1a, an active magnetic soundhole pickup (what Gilmour uses 8) ). With a moderate amount of EQing, the M1 does sound better, but after a bit of A/B testing, I decided I like the sound of both blended together, which I am able to do thanks to the dual inputs of the Radial Tonebone PZ Pre.

Since the Maton already has an endpin jack (mounted on a rather large steel plate) I'm not sure where to install the second one for the M1. I could put it above or below, or around the corner where an electric gat's jack would be. Or, I could source a stereo jack and replace the one that's there. But this would mean I'd need to use a stereo instrument cable and some kind of stereo signal splitter box on my board?

Keen for advice, or better ideas. Cheers.

TL;DR version: I have two pickups in my acoustic and need a jack for each but not sure if they'll fit. Should I make em fit or use a stereo jack+cable?

you might get around it if both are active and you install a blend pot.

Doesn't need phantom power no. The orig pickup takes a 9V battery, and the M1a takes a little button battery.
I can do the mixing at the pre-amp, but I will need to get a stereo>mono cable, or a stereo cable and a Y splitter box, as the Radial has two mono inputs:

Ahh, ok, thanks for the advice. I wouldn't have realised (and would have ended up with flat batteries).

I was wondering why the little 3.5mm jack that plugs into M1 pickup is a TRS jack, so that would explain it.

I might be seeking some professional help at some point. For the guitar that is.

Yeah, maybe. But that would require even more investment.
I do admit I was a bit swept up with the glowing reviews of the M1, but in reality it's not a perfect solution on its own. And needs a lot of EQing to get it to sound good.
So I think I need one of these TRSS jacks to run two pickups and a switch for the batteries:

On the plus side, it turns out input 1 on the Radial PZ-Pre accepts a TRS jack! :thumbup: So I won't need a stereo>mono splitter box on my board.

Does anyone have a spare TRSS jack lying around, or no where in NZ I could get one?
