If you are talking about the perm 12V supply then yes, all power latching modules are fed from the same fuse SC44 - 20A
There is an earth post adjacent to the modules behind rear panel if reqd so should be pretty straightforward for you
Does anybody have a picture of an existing module factory fitted in situ ??
The only thing holding me back at the moment is that the mounting bracket for the control module is on back order from Germany so i dont know exactly where the module sits, i need a definite position as i have made my wiring loom extra long ATM, when i have the position i can trim down the cables, measure & reproduce
