What JVS I/O are you using? Do you have the analog section of the I/O connected to anything? (On a Sega JVS I/O this is the medium sized 26 pin black connector.)
Officially you can connect the Sega JVS I/O to the Blast I/O with the analog loom: https://wiki.arcadeotaku.com/w/Sega_600-7143-004
*Analog Vcc and Gnd are not directly connected from the JVS I/O to the Blast City Cabinet I/O since it already provides +5v (Analog Vcc) and ground (analog Gnd).
Swap black and yellow if the axes are inverted.
Swap red and white if the axes are swapped.
None of the intermediate connections are necessary however. You can connect the joystick directly to the Sega JVS I/O.

Wow, I'm a bit more lost than I thought. I didn't think I need an i/o for this. I thought it was plug and play to the jamma edge.
Which sega jvs i/o do you recommend?

hmmm this interests me
Have you never used a Naomi before?Wow, I'm a bit more lost than I thought. I didn't think I need an i/o for this. I thought it was plug and play to the jamma edge.

Naomi is JVS era hardware. You need a IO board to interface controls. Most JVS system boards also use 31khz VGA though some hardware has exceptions and can do 15khz like the Naomi.
You can use a JVS to JAMMA IO adapter like the one you mentioned.
Thats only handling your controls and passing the RGB from the VGA into the RGB on the jamma edge essentially.
You will also need a power supply to run a JVS system board and a line level stereo amplifier since JVS spec says audio is line level RCA outputs.
If your planning to run a naomi on your Jamma cab you need all of this at minimum and you need to set the Naomi's dip switch to 15khz video mode unless your monitor is capable of 31khz.

For a Blast City I'd recommend just getting the JAMMA/JVS wiring harness: https://wiki.arcadeotaku.com/w/File:Sega-600-7143-001.jpg
Then you can use either the JAMMA or standard Sega JVS I/O. They both have the same connector for analog controls. The JAMMA I/O basically swaps the RA connector for a JAMMA edge connector for controls. The audio and video handling are basically passthroughs and potentially not very useful.
Don't spend money on a Capcom I/O if you have a Blast City.

Ofcourse I have, I just currently have capcom i/os. I gave away my sega i/os so I'll be buying one of those again. I may have that Blast harness somewhere as I've upgraded to the -001 loom. I'm just legit not well versed in jvs stuff.

Oh yeah if you have a Blast your basically set.
Sega made a JVS 001 Loom for RCA stereo and power for JVS things like the naomi.
The manual suggests using that very Jamma to JVS adapter sega made and you would get a kick adapter for it to if you needed it.
I think those IO's can also interface with Sega's VS billboard hardware used on blasts and versus cabs.
The cabinet should have the ability to carry analog controls through the main cabinet harness as long as you get one of their analog control addon looms made for that sega JVS to Jamma IO. Its in a manual somewhere.
You use the smaller header on top for analog controls.

So, I'm completely lost.
I have a jvs io now. The -001 cn5 26 pin header is too big to fit onto the jvs io and Capcom io. What am I doing wrong?
I have a Blast city, trying to hook up these damn analog sticks to play monkey ball on the net dimm. Any help? Pics? I'm legit lost.

That's because that's a 34 way header and not a 26 way header.
The loom goes to CN5 on the blast city IO - that blast city IO has nothing to do with JVS analog, it's simply a way to pass through data, it's responsible for the following:
What I believe you need to do (if it's anything like Monkey Ball that I did) is make a harness that will go from your joystick to the JST RA 26 way connection of the Capcom IO (I used the Sega JVS to JAMMA IO but it's the same concept)
This is a Sega IO, I believe the Capcom IO has the same connector:
This is what the harness looks like in a Naomi cabinet. It has individual P1 and P2 connections but then most panels use an adapter back to the 10 pin connector:
This is the Blast City analog loom:
It connects to the Blast City cabinet IO board, CN8:
And then analog controls are on the 10 pin connector under the control panel:

I'll see if Lemony can rig something up for me.

I’ve made one of these for myself and my future monkeyball setup.
I’ll hook ya up.

I didn't realise there was an official harness for analog to CN8 to use on the 10 way connector
Funnily enough, there was a time @Lemony Vengeance and I were talking about using CN8 as a pass through for Monkey Ball which I'm still yet to do - I just pass through my cable in that empty socket on the blast panel
Yeah, it's part number 600-7143-004, I actually found one on ebay easily. It has the CN8 connector for Blast cities as well as 10 pin connectors for Astros and Megalos.I didn't realise there was an official harness for analog to CN8 to use on the 10 way connector

It's partly why NOA-60061 exists. Pre Naomi analog games have their panels wired up for the 10 pin and the analog splitter loom is for making the Naomi wiring (2 8 pins) backwards compatible
