Default Evap System engine bay vs rear mount

So, my subie is coming to life, but I have an evap issue.

The setup:
97 impreza wagon (GFC) 2.2L received the motor from a 96 Legacy 2.2L, both 5MTs
Recently, I installed the Legacy ECU.

The Evap situation:
Most everything matched up 1:1, but the legacy used an engine bay mounted evap canister and the impreza had one mounted in the rear passenger side corner, by the gas tank. I mounted the Legacy's can in such a nice location in the engine bay that I favored it in place of the rear mount one, which I damaged a little while removing.

So, here's my understanding of the system with two Evap canisters:
The engine bay can has a smaller line going to the solenoid/intake. The engine would like to use this line to drink the gasoline fumes.
The larger line goes to the breather line back to the fuel tank.

The rear canister had a small and large line each with a clamp, I presume these to be equitable to the small and large lines up front. There was another un-clamped line labeled "purge" that goes to the purge solenoid. This is what worries me.

What I think I should do:
I think if I block every line in back, the fuel will evap into the front canister and draw from it. And, because the 96 Legacy ECU is in the car, and it doesn't have a purge solenoid, I can probably block the purge line and unplug the solenoid?

What does everyone think? I searched for a diagram, but only saw generic ones or other brands. I coulda sworn when I first came to the forum I saw something about an evap engine bay relocation, but I can't find that now.

Thanks again! Pics if you want and a full featured thread coming soon.

Default Codes

Throws a P1104 P0441 and P0507

Torque control circuit
Evap
High Idle

I've seen posts on nearly every forum from this guy http://www.ultimatesubaru.org/forum/...d.php?t=117527
http://forums.nasioc.com/forums/show....php?t=1955989

but no definitive answers.

He said he added the ground talked about in the first link, but also says it made little difference and the car runs fine.

My car, however, does not run fine.
Does anyone know about this traction control issue? I have no ABS or traction control, so maybe I should ground those pins? Any ideas?

It runs strong, but doesn't like when I let off the gas. Instead of engine braking smoothly, it will buck and sputter. After some engine braking, it generally runs poorly. I was hoping this would all be the broken speedo cable's fault, but that's fixed now and still has these issues.

Evap box is all blocked off and the purge solenoid is diconnected. What if I connect the two large lines in back through the purge solenoid, and leave the small one blocked, and leave the can in the engine bay connected?

Help please!
