Colour of EU flex

This should help.

please dont ask me iam colour blind ,but to overcome this i use a multimeter or a little light and test for current this way ,going by the so called wiring colours is a disaster for me not only the colour thing but the wireing can change colours owing to different suppliers of looms in manufacture ,they run out of one colour and use another ?? you name it i think i have seen it

Use a multimeter, and test each wire individually as you turn on/off lights. You won't need a colour code with this method.

Hi Red, Sorry to tell you this pal, but the Toyota's we have worked on do not have a colour coding format for most of the wiring loom. A cable which is loomed from the speed sensor can be one colour going in and another colour coming out because Toyota join cables of any colour, presumably for cost effectiveness. The cable can be identified from the pin number inside the management computer, or by downloading a pin out diagram from <www.allpinouts.com> Regards John.

rayburns07,

Thank you for asking me to help you with your problem. However, this is either not within my level of expertise or the question is unclear or there is not enough information and I cannot help you at ths time.

hi from uk the light on is saying for some reason exhaust emmisions are incorrect therefor missfire =runnig on 3 cyls resulting in one of cyls is emmiting unburned fuel into exhaust possibility ? so 1st diy checks you can do?= remove each spark plug and compare each as to colourof burning? you are looking for one ? plug difference in either colour or damp/wet ? or brown in colour compared to other three if you find one? then concentrate on this cyl ? this plug may be defective/not firing? look for crack/s in porceline ? or it may be the plug lead or the ign coil that feeds this lead with spark?to plug you could check spark to plug by fitting a good plug to lead then hold plug to engine earth turn engine over with keyignition on check if plug is sparking ? if not? may be lead or coil if spark present? then try with origional plug out of that cyl this thenif not sparking would suggest plug fault ? however if the plug of the cyl in doubt was brown more than other three ? this would indicate possible exhaust valve leakage/burning out ? if you try above suggestions that i hope you understand ? i hope you find fault ? however if you find fault and req further info? by all means keep in touch if you req advice/more info best wishes n/west of uk

washer = dark blue, - sw pin 4,
slow speed= black - sw pin 1,
fast spd = blue - sw pin 2,
motorbrake (parkstop) = white - sw pin 3.

As much as I remember from my Mazda most of the plugs don't have to many colours and they are different size and have different pins and sockets, try to match few of them and you will see it is not a big deal

Hi,
you did`nt say which engine so,as rule yes they have 4 pins but are identified by different colour sensor tops or the plug colour,if your give the V.I.N number and engine code to a dealer they will supply the correct 1 ,as VW modify all engine parts over time.

i have just put one in mine!

the only way you can do it if the plugs are not on, will
be to colour code the wires to pins. if you need the colour to pin codes
let me know.

All the best.
