anthonym Posted October 6, 2018 Author Share Posted October 6, 2018 My purpose here is to check all the connects are the same before crippling the car. I am suspicious one or more are different.Anthony Link to comment Share on other sites More sharing options...

rj Posted October 6, 2018 Share Posted October 6, 2018 Very difficult to see the connectors in detail in that image. Shouldn't be very difficult though. Link to comment Share on other sites More sharing options...
anthonym Posted October 6, 2018 Author Share Posted October 6, 2018 What's this for? I don't have anything I can find like it. This loom has an MBE connector and I have an Emerald, so wonder if it is related to that. Or not. I'll list the answers as I have them, below: (next message) Link to comment Share on other sites More sharing options...
anthonym Posted October 6, 2018 Author Share Posted October 6, 2018 where does the Black Econseal C177 plug in to? I missed that one. Link to comment Share on other sites More sharing options...
rj Posted October 7, 2018 Share Posted October 7, 2018 The green plug is for the barometric air pressure sensor. A little "box" that's som3.5x8x1.5cm - have one at home so can take a picture if you need.If I were you I'd start laying up the loom on the top of the old without taking anything off. You'll soon get it. Link to comment Share on other sites More sharing options...
rj Posted October 7, 2018 Share Posted October 7, 2018 13 are for the injectors; 11 for the crank position sensor and 16 is for the throttle pot. The brown (5a) will be for one of the water temp sensors at the water rail. Try the brown one :-p 6a is for the lambda sensor.I am almost certain that 17 and 18 are for the alternator and then 19 will go to the oil pressure sensor.My initial guess is that 15 is the air temp sensor - don't know the colour on an R500 - mine is off an EU3 and is green. It goes in the air filter backplate.Grey plug (14) attaches to the main loom2 & 5b are for the mfru. Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted October 7, 2018 Share Posted October 7, 2018 Here is the wiring for your loom, it can be found here: https://www.lotus7.club/sites/default/files/images/Docs/Guides/73414%20Engine%20Harness%20K-seriesR3_4_5.pdf CheersIan Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted October 7, 2018 Share Posted October 7, 2018 Just had a further look, here is what I have. But it comes with a health warning - some are not absolutes, but they can be easily confirmed with a test meter back to the ECU pin out using the above diagram. 1 = ecu2 = mfru3 = to the purple +12V feed on the main loom?5a = ECU Temp4 & 6b = look like earths from the wiring diagram I have6a = Lambda7&9 = look like oil and water temp for the STACK10 = Could be the fan relay control – if so it should go to pin 33 on ECU plug11 = Crank sensor12 = Coil14 = Loom plug (Grey)15 = Manifold Air Temp Sender17 = Alternator18 = Alternator19 = Oil pressure (STACK Sensor)58 = mfru13 Injectors (last on the line should be No1)16 = TPS Link to comment Share on other sites More sharing options...
anthonym Posted October 7, 2018 Author Share Posted October 7, 2018 @rj you mentioned EU3 has a green air temp sensor, which my car has, but it's EU2. This new loom has a white I think is for the air temp. I gather an EU2 MFRU works with an EU3 car but not vice versa. I'm perplexed by the permutations of that info. Far as I know (I use that word loosely) my car is EU2EDIT: change 5a on car: KB to GOTHE ASTERISK MEANS the colours of the wires in my loom are different, which assumes I have identified the right connector.here's where I am up to:The C numbers are from revilla's nonVVC png diagram1 C159 MBE connector Black2 C154 to MFRU3 12v *BS Brown/White BW male spade connects to female spade on the (famous) Purple wire, which supplies 12 volts.4 C183 B+ from Alternator, connect to battery positive (remote post). Clearly one solid thick cable.5a C169 *KB/KG Coolant sensor, Green/Orange GO (not KB) Black B located in coolant hose to rear left of engine, next to “fan switch”.5b C157 to MFRU6a C164 Lamda sensor connect to “sub-loom” (has six connects but only four are used).6b C151 to battery negative terminal (Not Bulkhead) (this is clearly a binding of several (black) wires.7 Oil temp sensor Green/Yellow GY Black B at bottom of dry sump housing/tower.89 C187 Fan temp “switch”, located next to the 5a coolant sensor.10 C179 NR to Solenoid Brown/Red NR on starter (or the “starter relay mod”.)11 C168 WU/UP White/Blue Blue/Purple I THINK this is the flywheel (Crank) sensor connect, but mine has a different wire pair that look home made, and I have a redundant connector with only a white to it, suggesting something happened to the black and it was replaced entirely).12 C156 NK/WB Coil. Brown/Pink NK and White/Black WB13 C521/2/3/4 Injector sub-loom.14 C162 THE “Grey connector” that connects this the engine loom to the Main loom.15 C174 *KB/GB Air Temp sensor Green G Black B.

I think. Brown/White and Black - Note the BROWN/WHITE is doubled being TWO Brown/White wires terminated as one. The wiring diagram shows these two wires terminate one to the Grey Plug on Pin 8 and the other to ECU Pin 27 NOT PRESENT?C177 Stepper motorC152 Charcoal canister purge valve Link to comment Share on other sites More sharing options...
anthonym Posted October 7, 2018 Author Share Posted October 7, 2018 Ian thanks, I haven't compared your list yet, but you have identified Stack bits which I was thinking were ECU sensors. edit: @jk wondering if this editor allows us to use tables..

anthonym Posted October 7, 2018 Author Share Posted October 7, 2018 @rj, yes please for pic of the barometric box. I am wondering if the pressure sensor is built in to the Emerald K6 (pretty sure K6) and that's why I can't find it. Link to comment Share on other sites More sharing options...
anthonym Posted October 7, 2018 Author Share Posted October 7, 2018 just a little heads up for anyone like me looking at the colour coding on the actual wires, some of the colours are invisible or different unless viewed with a bright white light, like a good torch. I guess daylight should work, but I haven't tried that. anthony Link to comment Share on other sites More sharing options...

EEK Posted October 7, 2018 Share Posted October 7, 2018 Barometric is built into the emerald as internal sensor, you must be using it otherwise it would run like a pig over all the high passes.http://www.emeraldm3d.com/k6-ecu-info-and-specification Link to comment Share on other sites More sharing options...
anthonym Posted October 7, 2018 Author Share Posted October 7, 2018 Yes exactly what I was thinking.. I am curious where the box would be and if it's still present, 'cos I can't see anything. .. it's nice to be doing this on the sofa! Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted October 7, 2018 Share Posted October 7, 2018 I've seen them on the scuttle before, normally similar to: https://shop.euroimpex.lt/en/dalis/17732/air-pressure-map-sensor-manifold-boost Link to comment Share on other sites More sharing options...
7 wonders of the world Posted October 7, 2018 Share Posted October 7, 2018 M3DK K3 and early K6 Emeralds ran these an option wire to pin 34, the pre wired loom has the wires twisted into a mini sub loom ready for use.Best to drop Karl a message with your ECU serial number and he will tell you.

Member Jonathan Kay Posted October 8, 2018 Member Share Posted October 8, 2018 @jk wondering if this editor allows us to use tables.Table creation tool:Trying that:1those that belong to the Emperor2embalmed ones3those that are trained4suckling pigs5mermaids6fabulous ones7stray dogs8those included in the present classification9those that tremble as if they were mad10innumerable ones11those drawn with a very fine camelhair brush12others13those that have just broken a flower vase14those that from a long way off look like flies That seems to work.

anthonym Posted October 8, 2018 Author Share Posted October 8, 2018 hmmm.. not really very useful because we can't copy and paste data in to it edited to add "en mass", far as I can find, looks like we are expected to be entering data in to each table box, I think - and pasting table type data (like form excel shown further below) creates a bit of a mess. How did you populate your test table?test content deletedBUT the image cannot be zoomed to make it readable; so export it and load and zoom that, only to find the image has lost its resolution so is all fuzzy.

Member Jonathan Kay Posted October 8, 2018 Member Share Posted October 8, 2018 I pasted text into each cell. i don't know if there's a way of importing tabulated text.For your purposes I'd consider:Managing the table in whatever you likeExporting it as a PDFUploading that to the forum.Jonathan Link to comment Share on other sites More sharing options...
anthonym Posted October 8, 2018 Author Share Posted October 8, 2018 yes I just did that, that image above.. I'll delete that test message shortly, think it's a bit messy for the thread. thanks Link to comment Share on other sites More sharing options...

anthonym Posted June 5, 2019 Author Share Posted June 5, 2019 For posterity I am recording here my thanks to RevillA who travelled to Switzerland and fitted my new loom, including changing the ECU plug to the Emerlald K6 which alone is no mean feat. On top of this the Alpine Winter was fast approaching and it was C O L D in my unheated garage.Thanks.Anthony Link to comment Share on other sites More sharing options...
