Help please with elec problem

[rykev]

Hi all
Looking for some advice please.Tuscan II 2005.
Everytime I turn on the ignition the boot release operates,also happens sometimes when changing gear,and as of tonight if I roll the car backwards and forwards it goes beserk.
I know it is probably going to be a poor earth but was wondering if anyone knows where the main earth pick up points are.
Any ideas would be gratefully received as I have had enough of using the manual boot entry as the elec has to be disconnected.
Thanks in advance.
Kev
