oneandtwo Posted November 24, 2012 Share Posted November 24, 2012 I'm fitting a replacement uncut and unmodified late 200TDI wiring loom into my K reg 90 with a 300TDI/R380 conversion. It's all wired up but I have a couple of odd wires I'm unsure where they go or what they are used for- First ones are black lead and yellow/black lead with spades on, about 1ft long, coming from main loom just where it enters engine bay through bulkhead. Next one - three way connector - green, brown and black, exits main loom by heater unit. Brown has a long tail to it looking like it goes direct onto the battery? Last one (at the moment!), slightly chunkier white lead with brown trace coming from main chassis loom. Thanks! Quote Link to comment Share on other sites More sharing options...
western Posted November 24, 2012 Share Posted November 24, 2012 plain black is Earth yellow/black tracer is feed from glowplugs timer relay to glowplug number 4 plain brown is a 12v feed not ign controlled plain green is 12v feed ign contoled brown and black is this 2 plain leads or 1 lead with a brown/black tracer ??? can't find one of those colour combination in wiring diagram, if plain single colour then brown is 12v feed from battery & black is earth white/brown trace is 12v feed from battery to glowplug timer unit would be happy to meet up as my 110 has the same wiring fitted, so you can see without guesing, I'm about 10miles from you.

oneandtwo Posted November 24, 2012 Author Share Posted November 24, 2012 The black and yellow / black lead don't seem to be for the glow plug - It already has the all the glowplug wiring coming off the timer relay in a separate loom, this is all wired up fine and they operate as they should. These wires both terminate in spade connections and are bound together. The second is a three way rubber bullet connector - I didn't look at the colours properly - poor lighting! It has green wire, brown wire and black/slate wire. It comes off the main loom in the heater area. The third wire again I got the colour wrong due to lighting, it is actually white with purple trace, it comes from the chassis loom not the main wiring loom, and is heavier guage wire, same as the rear heated screen wiring. It could be that these are just unused connections for non fitted options? All my other Defenders are 300TDI's - much better with the multiplug connectors! A friend has a L reg 200TDi down the road with exactly the same loom but is away at the moment. Thanks! Quote Link to comment Share on other sites More sharing options...
western Posted November 24, 2012 Share Posted November 24, 2012 if the spade terminals are small version, they will be for the dash choke/glowplug warning light, if not required just safely terminate them. white/purple trace shows as from coil to ballast resistor/start soleniod for petrol engined vehicles, so not used in diesel engined vehicles black/slate on mine is a earth for rear screen heater via the voltage sensitive switch prevents rear screen heater use when ign/engine off, to prevent battery drain.IIRC it also connects into the factory split charge loom, not fitted on your vehicle. hope these help Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted November 24, 2012 Author Share Posted November 24, 2012 Thanks. They don't correspond with anything on the vehicle so I guess they are all spare. The yellow and black small loom I think is for N/A engines without glowplug timer setup. The other wire I can't find where it goes is black with a red trace, taped to a black, behind the dash, these are the small warning light type female spades but they both have adapters to make them standard sized male spades.

western Posted November 24, 2012 Share Posted November 24, 2012 just to confirm the 3 way connector, black/slate trace,green,brown is definitly the split charge connection to a additional harness. black/red IIRC is to make the hazard switch red warning light [in switch] work, there are 2 small male spade connections on the sides of the switch. one wire to each side, doesn't matter which side, the put the bulb on when hazards are switched on Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted November 25, 2012 Author Share Posted November 25, 2012 Excellent, many thanks. Should the brown of the split charge connector be connected to the battery? There is a long brown lead coming off the battery terminating in a bullet that appears to connect to the brown bullet of the slpit charge connector. Learn something new everyday, In the eleven defenders I've owned I've never realised that there is a warning light in the hazard switch! It's obvious that is whare the wires go now as they are coming out of the hazard switch part of the loom. Thanks for your help! Quote Link to comment Share on other sites More sharing options...
western Posted November 25, 2012 Share Posted November 25, 2012 just checked my truck, that brown wire from the battery is connected to the 3 way split charge plug, the wire runs along chassis rail & up bulkhead to the connector. your welcome Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted November 26, 2012 Author Share Posted November 26, 2012 All connected up with zero cutting and soldering, no crimps or bodges anywhere, back to how it should be after a previous owners alarm instalation and god knows what else they had connected into it but never seen a loom like it. Turned it on and had issues with the warning light panel, it would turn on the front heated screen light for the glow plug light for 5 seconds and nothing else would light. It was a late 300tdi panel with the glowplug symbol not choke. cleaned all the connections but no other lights would work. Swapped it for a 200tdi panel and works fine with oil, battery and fuel lighting up and the cold start light in the right place. I guess the 300tdi panel is knackered although still cant work out why it lit the heated front screen light! Quote Link to comment Share on other sites More sharing options...
western Posted November 26, 2012 Share Posted November 26, 2012 different printed circuit, some 300tdi warning lights are in different locations to the 200tdi panel, you could move the connections in the panel plugs to get the 300tdi version working. no heated front screen light on dash panel, it'll be the heated rear screen light you saw lit. rear one is rectangular, front one is curved like the wiper sweep.

You mean like this symbol It was lighting the heated front screen instead of the low fuel warning light which is in the same place on 200's. It has been so long since I've had a 200tdi I'd forgotten about the low fuel light and how annoying it is when the tank is 1/4 ful and it starts blinking everytime you go over a bump.

western Posted November 27, 2012 Share Posted November 27, 2012 Not seen that warning light panel before, not sure if that icon is original LR though, might be a previous owner mod. Yes the low fuel light can be a bit persistent at times. some 300tdi's didn't have the low fuel connections or light/tank unit fitted, Quote Link to comment Share on other sites More sharing options...
bluehaze Posted November 29, 2012 Share Posted November 29, 2012 Never seen a warning light panel like that before - where is it from? Quote Link to comment Share on other sites More sharing options...
western Posted November 29, 2012 Share Posted November 29, 2012 from a 300tdi without low fuel level warning, someone has added the front screen demist symbol, it's not a genuine LR symbol on those models. Quote Link to comment Share on other sites More sharing options...

Actually the panel and demist light is genuine, I have three 97/98 300TDi defenders, all three have the front heated screen warning light. It's the later panel from the 1997 / 1998 model years. they also have the proper heater plug logo istead of the old choke logo that earlier 300tdis had.

Just found I had one of those late panels a while ago, wasn't aware it has the front heated screen icon, it was this panel, sold it a while ago, I'm using a td5 panel now, if you use the slider zoom on the link you can just make out the icon above the rear fog light icon. http://smg.photobuck...Y7zeBJqBTc5.jpg Quote Link to comment Share on other sites More sharing options...
