American PCIII USB !!! HELP !!!

I have recently purchased a power commander for my sv650s k4 . I am having problems with a flat spot between 2000 and 4000 in the low gears and hoped this would sort it . I have a scorpion can and k&n filter , they have been installed from new with no remapping done . My problem is this . I purchased the PC from ebay in the USA as it was £155 new and with shipping . I have removed and reconnected the in-line blocks under the air box . However , the instructions then go on to say that the TPS connector should be removed and replaced with one from the PC . All I have left is a single grey wire with a spade connector crimped on and not a third connector block . Have I been sold a duff . Is the block missing . Are american connections different . And where does that bloody grey wire go ?
The bike seems to be running and the PC powers up OK . I am concerned as to whether I am getting the best out of it or not .
Some please help me I'm very confused.

Has anyone got a full UK spec power commander for the SV650s 2004 . If so , can you tell me about it's connections and how you fitted it please ?

You should have one wire connected to the Fuel Injection unit... (clips round the wire) then a spade connector goes into that.

The others should be a direct replacement for the main wires (big block connector) and then the wire to the battery!

Hope this helps

Well it's Eater weekend so I've time to explore the bike and get it sorted . Then I can use the bike to explore . You say the wire fits round it , do I have to plice any thing . Can you please explain in a bit more detail about where the wire goes . This will be the biggest thing I've ever done With my bike . All my other mods are just OEM direct replacements . I am very aprehensive about doing this , just in case I bugger things up . Any futher help will be invaluable to me .
Cheers mate .

What are you up to this weekend ?

If all connections correct, it might be that you having to download different fuel maps in order to experiment to get best results from PC.HTH

After a lot of digging I found it to be the pink and white wire on the TPS . Its finally up and running fine . Ihave set the throttle positions and loaded in a map for the closest to my set up . I am going out to play for the full day tomorrow . Many miles will be done around many twisty corners . Ill keep you updated as to how it works out .
