steve_d Posted March 16, 2009 Share Posted March 16, 2009 Make Model Year Would be a good start or are you talking about an aftermarket gauge you are going to fit to the dash yourself. Steve Quote Link to comment Share on other sites More sharing options...

Goober Posted March 16, 2009 Author Share Posted March 16, 2009 sorry. its a 300tdi engine in an 1987 defender orininaly had a dt engine in. but i wouldnt mind fitting a new gauge in ther. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 16, 2009 Share Posted March 16, 2009 with the info given i would say with some cable!! probably 2 core!! Why would you need two core cable to connect one wire? If you've found where to connect the wire to the engine, you need to find the other end of that wire (the clue is usually in the colour code of the wire) behind the dashboard and connect that to the gauge. If it's a genuine gauge then it should be fairly obvious if you look behind the dash. Quote Link to comment Share on other sites More sharing options...
western Posted March 16, 2009 Share Posted March 16, 2009 use the sender with the green plastic insert & it'll work with the existing gauge, the gauge end needs a Male spade terminal fitting to the wire [blue with Green trace] & the sender end needs a female bullet connector fitting to the wire, you'll also have to close up that connector so it fits snug on the sender pin terminal.

western Posted March 16, 2009 Share Posted March 16, 2009 Yep, that's about it, the back of the gauge should have a 12v feed on a plain Green wire connected to a Female spade terminal & a plain Black wire connected by a ring terminal to the stud that the gauge U clamp fits to, the ring terminal needs to be under the small knurled nut & on top of the U clamp, so it's sandwiched between the 2, the gauge illumination should be intact & wired up to a red/white wire, as per the other gauges. if you can add a photo or 2 it'll help us check the connections with you.

Hi sorry i still dont understand it. There are some wires connected to the gauge as the pictues show, there are also two wires hanging as shown. I have put some pictures up from behind the dash and the engine. The wiring is from the original 2.5dt i think and fitted the loom to the 300tdi engine, i have the wiring for the 300tdi spare so could use the wire that plugs to the engine.

western Posted March 18, 2009 Share Posted March 18, 2009 the other wires that are currently connected are all in the correct place, so leave them as they are. Quote Link to comment Share on other sites More sharing options...
steve_d Posted March 18, 2009 Share Posted March 18, 2009 I'm confused. If the gauge is already fully installed in the dash then why is the sensor wire not there in the loom? Steve Quote Link to comment Share on other sites More sharing options...
Goober Posted March 19, 2009 Author Share Posted March 19, 2009 I'm confused.If the gauge is already fully installed in the dash then why is the sensor wire not there in the loom? Steve I dont no. i am using a previous loom from the original engine, i then installed the 300tdi engine and noticed it wasnt there, all wiring was there apart from the temp to engine bit. so im having to use the wire from the 300tdi loom to attach gauge to engine. for some reason all the other wires are in the back of the gauge, Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted March 19, 2009 Share Posted March 19, 2009 As I recall, the 2.5D has a spade terminal connection for the temperature which is about 2" too short. The 300TDi has a bullet connection. You may find the right wire on the loom, just with the wrong terminal... Quote Link to comment Share on other sites More sharing options...

Hi it was a 2.5dt. yes i have the bullet part and will just connect a female spade to the other end of the wire and it should fit the back of the gauge.
