2 places to check, 1st is on the roof part itself, The plugs should be plugged in on each side (near the big locator pins) 1 of my hardtops came with 1 of these unplugged so check them 1st.
2nd of all, it’s also worth checking the “ring” on the car before you put the roof on, look in the big locator pin hole and there’s a metal ring around it on both sides, 1 side on mine broken in 2 so I have to make sure I hold it in place when putting roof on otherwise it doesn’t make a connection.
Hopefully that helps?!
