Upgraded light loom

[Keyo 47]

The passenger side main beam light is working intermittently , I have an old aftermarket upgraded loom on it and I have to wiggle the cable near to the relay and it sorts it out.

 

Was just wondering , have seen soom uprated looms on ebay for about £25.00 , does anyone know the best one available on the market at the moment and where to source it?

 

Here is the one on ebay. Is this the best one to buy

Thanks

Pretty sure that won’t fit mate. I’ll see if I can find where the one I got was from.

 

 

I think it was off this guy on EBay,

but not listing the loom anymore, you could message him.

I don’t think Rayne Automotive do them anymore. They aren't listed on their website either.

I’m also interested if any are available.

Depends on how much you want to spend - German fleabay has a completely weatherproof plug and play version with OEM connectors for silly money:

I'd say you'd never need another one though!

 

They are easy enough to make though (instructions can be found on the Mk2 forums) and if you can source the connectors you could even upgrade a cheaper one to the same spec. I built something similar for my car and it's lasted over 8 years with no problems apart from the time a coolant host burst and one of the fuses shorted out.

 

Go for 3 or 4 relay versions if you can for extra safety.

Thanks Fen , my budget does not cover for that much but Im sure you have found the best one on the market! Anyone else come up with anything ? Im sure I read on here that a member was making them ?

 

Found this as well off ebay ???

Yeah, that last ebay one might do the trick - ask to see some proper pictures of the loom first though.

Ive got a feeling it might be the same as the other one I have posted because it also advertises for the Golf MK2. Who was the member making these anyone remember ?

[Keyo 47]

I have asked the seller to post me a picture and also how many relays there are, does look like an English seller that has specialist electrics for sale and says he owns a Corrado so might be good.

[fendervg 29]

It probably won't have the OEM headlight connectors on, but I think these are still available, and you can buy a wiring repair kit from VW with the pins on the end that allows you to connect it - otherwise you end up with spade connectors, which are not ideal.

 

I cut out the male end of the connector socket part from an old knackered headlight casing and wired it up so that the loom is plugged straight into the existing feed using the female socket - more or less the same as that German loom, but it looks like they were able to get hold of factory sockets and have one for each side for the sidelights. That loom is seriously expensive, but it is fully sealed, plug and play and 4 relay - on these dark nights it could be a lifesaver and we often spend more on less important bits. I'm tempted to start saving and buy one - I'll let you know what I think if I do.

My x relief loom at the moment has spade mating on to the OE plug and can only see one Relay , it must be old as the connectors on the battery look at least 15 years old so must of been some of the first uprated looms.

 

If it the ebay one says its just for the headlights not including fogs , he is an electrician expert by the looks of it so has probably modded all his lights.

I will post a picture of the loom once the seller emails me over one, oh hold cant post on here grrrrr.

[fendervg 29]

Yeah, there's been lots of different types over the years, different number of relays, some do high beam and low, some both, some include sidelights in the wiring, and I've even seen an option for relayed fogs (probs not a good idea as most are afraid to turn them on in case the lenses crack!). They kind of evolved from the Mk1/2 looms and then the OEM connectors were added as the headlight casing and socket pin-out are different on the Corrado - the Golf looms just had standard H4 connector on them as far as I can remember.

I saw this one too, but wasn’t impressed with the photo showing bumper indicators and fogs getting brighter as well as headlights. Can’t see indicators getting brighter because of headlight loom.

Hi Shaun ,

 

Hope all is well have you fitted your seals yet mate, bet they lift the car nicely ?

 

Are you on about the loom from Germany the expensive one ?

Ha ha - "electrician pervert", I like that - brings all sorts to mind - the Doc from Back to the Future being one...

I’d be interested to know what you think of it. Let us know.

I have to say there's only so much you can do with upgraded looms and so on. Even my '96 car was beginning to fail MOTs because the lights were pathetic. The only solution was to have the headlamp reflectors resilvered. Costs a lot more than a wiring loom tho ..

[fendervg 29]

I think the best bet is to get your reflectors re-coated and use a loom. Even with perfect reflectors, the voltage at the headlight will still be lower than it should be and cause a drop in the light output - this is simply a design flaw and facto of life for early VAG cars because of the way the loom is run and the current is routed through the headlight switch.

 

For example, H4 bulb output at different voltages:

13,5V 55Watt

12V 51Watt

11V 44Watt

10V 38Watt

9V 31Watt

 

If you go and measure yours at the headlight connector, you'll be luck to see 11V there, more 9-10V

 

Of course some of the newer uprated standard bulbs such as Osram Nightbreakers or Bosch +150 will help too.

Yeah, very aware of this too. At least the beam pattern is now clearly discernable after the reflectors are fixed though. There's no amount of bulb power can fix this if the reflector is failing.

Any follow up on this?

I'm curious to know what you think of your purchase.

 

Cheers!

[Keyo 47]

To be honest it looks well made but it is not yet fitted and tested, it was purchased as a spare. I'm far from been knowledgeable about electrics to make a review, I would post some pictures on here for you guys to examine but unfortunately this site is not functioning to allow that.

Anyone on here that is clued up on upgraded light looms, I can whatsap/text you some photos of the loom and you can post on the thread your opinions ?? Send me a private pm on here with your contact details and ill send them over.

 

Cheers.

[fendervg 29]

I reckon re-coated reflectors, Osram Nightbreakers and an uprated loom will give you the best of all worlds.

 

If the lens is cracked even slightly or not sealed properly then you'll end up with corrosion on the reflector unfortunately.
