Connect a 2 1/4" Ultimarc trackball to a Mini-PAC using a Happ harness? :)

Thanks again for the very informative info mayhem! Now, I do have the Mini-PAC harness for Happ trackballs and I also have the Opti-Pac harness going from the trackball (was attached to the trackball when I got it); can I cut the plugs on the Happ cable (on the Mini-PAC harness) and solder it together with the harness attached to the trackball?
Take a look at this picture and hopefully you understand what I mean:

Cut !!!! No De pin them ...... Dont cut.

I had the exact opposite problem you did, I had the ultimarc trackball harness, and I needed the larger Happ trackball connectors. I ended up cutting my connectors off, and hooking my trackball up with quick connects.
Maybe this will help:
On the wires that came with your 2 1/4" trackball, black is ground, red is +5v, yellow and green are the axis inputs. Use this chart as a guide for X and Y axis info:

On your minipac harness (larger circles in your picture):
Top Circle
Middle Orange: +5v
Red: Gnd
Outside Orange and Yellow: axis inputs
Bottom Circle
Yellow: +5v
Black: Gnd
Red and Brown: axis inputs
Really the most important thing is to establish power and ground. From there, you can test and swap the axis inputs until you get the up/down left/right response you need.
Hope this helps!

That info definitely helps a lot! :) It doesn't look like it's too hard to fix either. ;)
The only thing is, I'm not very good with the soldering pen, so de-soldering the Happ connectors and pinning the wires to the Ultimarc connectors might be too advanced for me. I was thinking of just cutting the Happ trackball wires off, twisting them together with the Ultimarc wires from the trackball and solder it + put some shrink wrapping around it. Should work fine, right?
Thanks again for your help guys!
smalltownguy:
Yeah, that's what I'd do. Just leave an inch or so of wire left on the connector when you cut it off, so if you ever need to use them again, you'll have some wire left to strip.
You can twist the end together and solder, or you can use these:
Fully insulated wire connects. I little tricky to get solid connections, but a bit easier to disconnect down the road.
