The Glanza loom will not match up with your interior loom or match the fusebox in your UK EP91.
You can change the interior loom and dash and clocks and all other bits attached to the interior loom from your UK spec for Glanza bits, or you can splice the UK loom with the bits needed for the Glanza engine control.
You have the easy bit done, fitting the engine. Its now the fun begins lol. You can leave the starting and charging systems in from the UK loom but the engine control for your 4efe engine needs removed and replaced with the 4efte engine control wiring and ecu.
Hope this helps you out a bit.
