I know the subject of fixing the slow electric windows on the Scorpion has come up many times with many viable and smart solutions, but I have alternate method that I thought I'd share with the interested among us.
After studying the wiring diagram on my Scorpion and knowing that I had already installed an ignition relay for most of the switched loads on the vehicle (thereby reducing the need to run a dedicated power lead to the window motors themselves), I realized it was possible to install a relay pack to bypass the window switches fairly easily by just installing the relays as a jumper between the window switch connector (C31) located in back of the radio/HVAC console. Once I wire the kit up, it should be just plug and play.
So, I went about trying to source the components I needed. First, I needed to find some Fiat connectors, especially the 6 pin connector used in C31 (found them on ebaY). Then I sourced some 0.25" male and female spade connectors with tangs that will snap into the empty Fiat connectors (http://www.easternbeaver.com/Main/Elec__Products/Connectors/250_Connectors/250_connectors.html). Finally, I sourced four Bosch style SPDT relays with plugs and pigtails (similar to these: [ame="http://www.amazon.com/Relay-Harness-Bosch-Style-40AMP-HRNS/dp/B005HFYE1O/ref=sr_1_1?s=automotive&ie=UTF8&qid=1394410465&sr=1-1&keywords=relay"]AGT (5 Pack) 30/40 AMP Relay Harness Spdt 12V Bosch Style (40AMP-HRNS) : Amazon.com : Automotive[/ame]). Here is everything before I started...

The next step was to plan out the wiring diagram so the assembly would be an elementary task. I needed to figure out a way to wire up the relays so that I could just unplug the 6-pin connector and install this kit in between. I wanted to use the fused power from fuses 9 & 10 (i.e., the regular window fuses) to directly power the windows through these relays and just use the switches only to fire the relays. Here is the wiring diagram came up with and drew for all those interested with an online tool:

It was then time to crimp all the wires and install them into the connectors and put them all together...

As for the results, I have to preface the following videos by saying that I captured the before and after window operation without starting the car (i.e., battery only) on a 32 degree day. The car had been sitting for several weeks without starting, but the battery was topped off with a trickle charager. Here's the before:

And here's the after:

Okay, so the after is still a bit slow and the driver's window is noisy (needs some lube), but both windows are noticeably faster by a few seconds both up and down. An improvement and a relief from possible switch damage from the high loads incurred from drawing direct power straight from the switch.
