hodge Posted March 26, 2012 Share Posted March 26, 2012 Hi guys On a 5 speed manual box there are 2 sensors. 1 to the rear on the drivers side which I assume is the speed sensor. 1 on the passanger side of the box. Can anyone tell what this is for please??? It is a 2 pin plug with I think a grey connector on it. Thanks John Link to comment Share on other sites More sharing options...
Dr_Doom Posted March 26, 2012 Share Posted March 26, 2012 (edited) Is it a reverse gear sensor? That's what i thought it was when i took it out by mistake thinking it was the speed sensor! It looks like this (if you've not already removed it); Speed sensor looks like this; Edited March 26, 2012 by Dr_Doom (see edit history) Link to comment Share on other sites More sharing options...
Swampy442 Posted March 26, 2012 Share Posted March 26, 2012 As above, right hand side is speed sensor (if its from a mk3 supe it will be cable drive so look different) and left is the reverse light switch Link to comment Share on other sites More sharing options...
hodge Posted March 26, 2012 Author Share Posted March 26, 2012 So how do I connect it to the TT loom. There's not a plug that fits into it. Do I hardwire it in?? Link to comment Share on other sites More sharing options...

Dr_Doom Posted March 26, 2012 Share Posted March 26, 2012 So how do I connect it to the TT loom. There's not a plug that fits into it. Do I hardwire it in?? If it's an Auto TT loom then yes, it needs hardwiring in to the big plug (not sure about a manual loom, could be the same) This is quoted from the NA-TT thread - 'the big plug with the most wires in (6/7 wires?) has the reverse light wires in and these need joining to the reverse light switch. You just need to put 12v to each one until you get the right one that brings on the reverse lights, and the 2 thicker wires on the connector need snipping and joining together. The only other one thats used is the speed sensor which has the right plug on anyway. The ones that aren't used, we just tape up and tuck out of the way.' There are some good pics and info on how to do it on this page - http://www.mkiv.com/techarticles/auto_to_6spd_swap/install_6spd/index.html Link to comment Share on other sites More sharing options...
