the internal wires and terminals.
(1) Crimp the internal wire (yellow) of the DC-Speed Control Switch [46] and the internal wire (black) of the
LED Holder [42] together with Connector 50091 (10 pcs.) [47].
(2) Solder the Terminal [52] and LED Holder [42] (brown internal wire for 14.4 V or red internal wire for
18 V) to the (B+) terminal of the DC-Speed Control Switch [46].
(3) Solder the Terminal [54] to the (B-) terminal of the DC-Speed Control Switch [46].
(4) Fasten the Holder Spring [51] and Terminal Piece [53] to soldered Terminals [52] and [54] with the
Tapping Screw D4 x 10 [50].
