my mate mike used to work for lazerline in runcorn ...
never fitted them my self ,,dont like them TBH
think there still there.. have a look in the yellow pages or do a google search uk
for lazerline installers....IF THATS ALL YOU WANT they should tell you what to do
via the remote .. ..but im sure its a jumper ..to do it Permanently
