Of course I could just be putting a multimeter into the wrong terminator holes to check connection... Plus the various references (including from SIP themselves) don't seem to reference the same connections consistently.

To accompany the pics, here is what SIP says the connection are:
Connection:
M = Kill
1 = concutor / Parking Light
4 = white/black cable from SIP speedo changeover switch
6 = Low Beam
7 = High Beam
8 = Horn
