HELP !!

[JimmyBoy-S]

I brought a hawk central locking kit (electronic solinoids) off ebay for my 6n and got round to fitting it yesterday.
Wired both doors up and tested it, well when the driver door is unlocked the passenger door is locked and the other way around.
Also because iv got a smoothed tailgate (with a boot solinoid popper) when u press the remote sumtimes the boot unlocks too


Would running a seperate wire for the central locking from the battery stop openin the boot??

Any suggestions of how to solve these problems??

Any help would be appreciated

Thanks
