I run it on the same set up now in my primastar.

i thought about that but the instructions say d+wire so it wont flatten your main battery the d+wire aparently comes live when you switch on your engin and goes negertive when you turn it off i think it will be better this way as it dosent interfear with the main battery charging it has a 20 amp fuse in line with another 20 amp fuse and a 1 amp fuse its a good heavy duety relay so i am told may have to take it to a sparki ;)

The wire you want is the thin one,... its just an indicator lamp wire and carries very little voltage. The thick wire is the charging wire... avoid connecting to that!
