some bollox being spouted on this thread! 60/40 split? wtf...the wires earth out on the inner wings and can be got to without removing scuttle..easy to do anyway..the power for the screen can be got to on the drivers side but the passenger it is a bit tight..it is right behind a plastic casing behind the battery..done a screen on one not long back and was eaasier when i removed battery but not essential..if you need to remove scuttle do it with the bonnet down
