I’m fitting aftermarket LED DRL strips and need to clarify which wires on the front headlight clusters go to which light. I’m after the ground, side light, and indicator. I’ve run a multimeter over it and I’m assuming brown is ground, black/green is indicator etc but If someone can list them by wire colour/PIN number that would be great. Cheers.

Evening all, I want to bench run my 1100 hb engine, but forgot where the wire from the condenser on vac adv dizzy goes, is it to negative? Thanks

I am in the process of tidying up my radio wiring harness. It's been butchered over the years and now is a lot tidier. I can't identify one wire. It's blue and white in colour and is connected to pin 10 of a 12 pin plug (with the rest of the radio power feeds). Is this the illumination feed for the car radio? If so then it should be connected to the orange wire of the ISO connector? There is also an unconnected small brown plug with a blue/white wire buried next to the 12 pin plug. Is this the illumination feed for an unconnected switch? (say some optional extra like heated front seats)

I have two wires going from Alternator. One goes to the battery positive (thick black cable) and the other is a single little blue wire that goes to the starter motor. In between these cable there is a plastic clip that holds the cables to the alternator. I have a thick cable going from starter motor to the battery positive. I have a thick black cable going from negative battery terminal to the gearbox housing bolt. In between this cable there is a fixing to the left side chassis. I have a ground cable going from top back of rocker cover engine to the engine bay back wall. That's it. I'm sure this is how it was before I pulled all the cables out as I have no other cables remaining. My question is; is this right?

I'm about to replace my stolen stereo and get my rear 6x9s wired in. I don't think my car has the wiring for rear speakers. Can anyone tell me the route the wiring takes? Down the passenger side carpet? Which holes does it come out of in the boot? Also which path does it take around the rear hatch? The stereo I'm getting is a Sony MEX-GS820BT. Would I need to upgrade the power wires? The manual states rated power consumption 10A. thanks in advance https://www.sony.co.uk/electronics/in-car-receivers-players/mex-gs820bt

I have a mk4 Polo which has had a break pad warning light on for years. Break pads regularly checked and deemed good, so put down to a wiring fault. Car had cam belt replaced about a year ago, plus relatively new battery. It runs well but changes to MOT rules now include warning lights. Any suggestions on cost of sorting wiring fault, as seems a shame to scrap a good car.

Yes the age old question of swapping a 1.8t into a polo but not any polo a mk2f polo. What im after is some advice about keeping the original clocks in the polo but running a 1.8t but I’m struggling to work out what I can do for a loom to get it all working correctly, ideally I need the obd port for possible remapping in the future and if the engines running rough. I’ve got both cars next to each other so it should make life easier but I doubt that 😂 It it will probably be easier if I bullet point my answers any advise is welcome Can I run 1.8T (AUM) on it’s own with out the immobiliser? Can I have it push butting start with out needing the key and clocks? Can I use the existing ECU? What driveshafts should I use? What brake setups are best for this? Would it be easier if I got a new pedal box because the AUM is DBW ? Thank you in advance Harley

Hi all. I've bought my self a new car stereo and have decided to wire this one in properly with a proper ignition feed rather than bodging a constant 12v feed. Trouble is I don't have an obvious ignition on 12v feed. What's the easiest way to to go about plumbing one in. Also when climbing under the dash I've found two unused plug and socket (pictured) and don't know what they're for, any ideas?

Hi,Could someone send me a photo of the wiring that plugs in to the sender unit under the back seat.They have broken off out of the plug! Thanks

Just got a 6n2 and the driver side electrics dont work. Ive looked at the wiring between the driver side door and the body if the car to find a broken brown wire thats previously been repaired and failed... Whats the best way to properly repair this? Also when i touch the wires the electric mirrors and locks work, passenger window also works but drivers window still wont work. I dunno how to fond out if its the switch or the motor. The motor makes a click noise when i push the button in one direction but does nothing

ive started a swap ..mk2 polo to 3f mpi injection etc the 2 yellow wires for the diagnostics ...the diagram i have shows it going to the interior loom white wire which is heater speed 1 ? doesnt sound right to disable the heater has anyone go a working diagnostic socket on a mk2 swap ...i need pics /help

I am mid way through a afh converaion on my polo mk3 coupe i was wondering if anyone could help with with some advice on wiring and what old looms i can get rid of i have a mk2 ignition loom coil and amp on order I've heard people say I can remove the old engine loom is this correct ? Do I need any wires or plugs off it if so ? If anyone knows of a build thread can you send me a link over any help would be appreciated thanks !

My left indicator is doing this strange thing every now and again and it's super irritating while I'm driving, it doesn't do it when indicating right but only does it on left When it does do it the indicator doesn't even come on, I've looked in the steering column and wiggled some wires about which seems to fix it for a short period of time and then it just does it again. Starting to think it's the actual switch but not sure, any help would be appreciated, thanks. Snapchat-276793547_000.mp4

Hello, I know there is a lot of threads on ABS and sensors but I guess every problem is unique, I have a 9N3 1.8T Polo GTI (07). A while back my ABS light had come on along with traction control permanently off, scanned the car and it came up with: ''ABS Wheel Speed Sensor Rear Left (G46), 008 - Implausible Signal - Intermittent'' I investigated and found some of the wiring had burnt through the exhaust but was soldered (badly) by the previous owner, I unplugged the sensor and pulled it through the car onto the rear bench, cut the bad solders off, stripped and crimped (upon inspection of the wiring the black was slightly discoloured, maybe from the previous owner putting too much heat on the wire), this worked fine for around a day of driving. Then the fault seemed to reappear, I again pulled the cable through the car, checked the wiring and repeated the same process, still didn't work. I then cut the crimps off and soldered. Now it seems the problem is very intermittent, the fault comes and goes very quickly. Sometimes it's on for a day then other days vanished and everything works fine. An output test for the ABS was also completed via VCDS when the fault was gone and everything checked out fine. Measuring blocks whilst driving shows no output from the rear left when fault is present. As I'm typing this I realise this looks very much like a wiring fault but I can't help thinking this may be something else. So far I've changed the sensor, the rear disk has also been removed and cleaned up any dirt maybe stopping the sensor from working correctly. My next idea is to maybe change the rear wheel bearing as it works with the sensor to output a signal. Any thoughts, similar experiences or little things I can check would be appreciated. Thanks, John
