don't know what the connectors are like. The OEM ones from the states were direct plug and play with no stanley knife required. I don't know of anyone who has bought these alternatives. Also bear in mind import duty & VAT possibilities.
chrome grill strips (actually a roll that you cut to fit) are available form halfords and look good

the english ones just need some lugs removing on the cable connectors with a stanley knife to work. Not rue plug and play but pretty close. 5 min job anyway
you will also need a discount code in order to ge this price. You will need to contact a mod or admin and he'll supply the code.
Not sure if MrF at MJP is back at work yet either but do try him or holdcroft.
and enjoy the forum
power ugrades is a bit of a weird one. ECU counteracts all upgrades unless you get a piggy back ECU. Doesn't stop you modding though if not just for the meatier sound.
sounds a bit like a non compatibility problem.
There is a list if compatible phones on the forum. If yours isn't on there it might be worth asking Bury Technolgies if it will be soon.
