its a relay mate it all comes apart without disconnecting anything mate, all i did was take this apart remove the case which just pulls out when you push the tab on the back, when the relay and base is clear and on its own the cable runs into the the balck casing, just hide the relay and base in there mate and put the lid on then mount your catch can there as low as you can mate fixing the catch can bracket to the car with self drilling screws if you were local would of give you a hand mate
Sounds a bit difficult. Will have a butchers on the weekend. Don't suppose you're going to the AmD rolling road day in February?
