Well got this fitted tonight, and i used both the standard cables with a minor technical adjustment involving a block of wood and yes you guessed it lol a hammer ;-) i did mount the ST220 TB bracket directly to the TB rather than using the stand off bolts that your supposed to use, also havent fitted the air filter yet as i had to repair a previous mod due to the ST220 bellows, TB and LPG adaptor being a good inch or so longer than standard, but i managed to lose it on the 57i ;-)
Standard setup
ST220 complete intake setup without LPG mixer
Side by side standard TB and ST220 with mixers attached
ST220 setup TB and LPG mixer
As above with bellows
I went for using the ST220 location in the bellows for the IAT cos i had to shorten the intake by shifting the 57i further down the rubber adaptor (Mine is from a MKIII Mongy, modded to fit) ;-), i extended the cables to reach as required
As an added bonus i also got my reverse lights working, thanks to scunny donating the plug from cat2 as i have a C2 box fitted from Dygs after he upgraded to ST200
So all in all a very productive day woohoo ST220 cant wait til tomoz lol
