| GTM21 Pin-outs
Hi My 1st post and straight into picking your brains. I have a GTM21 lead which has broken connections within the flat plug end ![]() ![]() Does anyone have the Pin-outs for these or would someone be so kind and unscrew the cover of their lead to give me the connections from the red wire end (the only remaining connection) Thanks. |

Anyone? My Mrs keeps getting lost without it, and she does have her uses so I wouldn't want her to disappear completely |

Stumbled across you post, I happened to have mine to bits the other day, Its wires were hanging out of the plug but hadn't quite separated, I made a note of the connection in case it ever broke completely. The connections go as follows: bottom x x x x brown green blue purple red top x x x x x brown black yellow red The red lead (+12v) is connected to two pins. The brown lead is also connected to two pins, via a short length of black wire. Last edited by nch; 07-17-2010 at 7:57 AM. |
