Andrew K Posted June 15, 2013 Share Posted June 15, 2013 On the picture below I know that the large grey plug on the water neck pipe is the water temp. Sensor, can anybody tell me what the smaller grey plug / sensor is and what it does? Thanks https://jza80.mkivsupra.net/imports/2013/06/418.jpg[/img]"] Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 15, 2013 Share Posted June 15, 2013 Water temp sensor There are two, one for the ECU, one for the gauge on the dashboard. Quote Link to comment Share on other sites More sharing options...
hodge Posted June 15, 2013 Share Posted June 15, 2013 Top one with 2 wires goes to ECU, bottom single wire to dash gauge. Quote Link to comment Share on other sites More sharing options...
Andrew K Posted June 15, 2013 Author Share Posted June 15, 2013 Thanks, was hoping I could put my defi water temp gauge in the smaller one, I still want the dash water temp to work as well and I can't put the Defi sensor in the top rad pipe as its a braided hose. I'm using a different water neck than the one pictured. Quote Link to comment Share on other sites More sharing options...
hodge Posted June 15, 2013 Share Posted June 15, 2013 Just drill and tap the top of the water neck. Quote Link to comment Share on other sites More sharing options...
Andrew K Posted June 15, 2013 Author Share Posted June 15, 2013 Just drill and tap the top of the water neck. Do you mean in the area were the 2 water Feeds have been welded up? I'm using the water neck pictured below as its already had the AN fitting welded on and it hasn't got the same part on it that's been welded up. https://jza80.mkivsupra.net/imports/2013/06/419.jpg[/img]"] Quote Link to comment Share on other sites More sharing options...
