I'm putting off tidying up my wiring loom in my beetle but it's a mess and don't know where to start to be honest.
It's a very early 67 model so I believe it was 6v but someone has converted it to 12v so there's alot of wiring that isn't in the standard diagrams.
Planned to label everything but it's gonna be a nightmare trying to trace it front to back
Any tips?

Planned to label everything but it's gonna be a nightmare trying to trace it front to back Any tips? Certainly have - Its 52 years old if its original and sounds like it's been cut & spliced / messed around with - it takes nothing for the insulation to fall off wiring of this age - it then goes to earth - if you are lucky it might blow a fuse if its a protected circuit - if not or if you are unlucky it will catch on fire - so here's the top tip - take the harness out and throw it away - you have a popular model of car and harnesses are available off the shelf for it - if you want a custom harness companies like 'Auto Sparks' will build you one - they are not that expensive when compared to the cost of replacing a burnt out car / insurance claim etc - pics below of the harness that I have just removed from my 1952 Jowett Javelin Basically a disaster waiting to happen - new harnesses on older cars are a fairly simple fit with a wiring diagram - my new harness was £230 so its a small price to pay for the piece of mind - but to start piecing together / repairing what you have is a complete wasted exercise

It's a real mess plenty of wiring that doesn't even match the diagram or isnt connected up to anything.
New loom was a consideration and will probably be the way to go. Probably won't take aslong either to fit

Feel your pain, 'cos I've suffered a rewire too!
New loom every time, safer, easier and cheaper in the long run. You can even get it spec'ed to your requirements.

It's been a while since I did a full loom replacement. Is there anything you would do before fitting a new one?

Dodgy wiring will lead to reliability issues and as mentioned above even fires, wiring of this era seems to vary greatly, some are fine with near perfect insulation on others it falls to pieces, the only way to be sure is to remove the loom, mount it on a board, strip all the wrapping off and inspect each cable along its entire length replacing any with stiff or damaged insulation. Oxidised brass or copper connectors can be cleaned in white vinegar and its a good idea to fit a modern fuse box and add fuses to non fused circuits.

The easiest and convenient option would be Buy and install a readymade one. Unless you have all the different gauges of wires, connectors and the patients to do it without it turning in to a birds nest

Unsure if I will need to add to this or not don’t want to be melting my new loom

Unsure if I will need to add to this or not don’t want to be melting my new loom Pick the phone up and talk to 'Autosparks' they will talk you through the process and build you the harness required - its a straight forward process and they will put you at ease with your questions - link below (and they will be far cheaper than VW Heritage) www.autosparks.co.uk/

As grumpynortherner says talk to them. Colin

Had a look at some of the off the shelf looms mixed reviews on them most don't come with whats needed.
Heard a good few things about some independent guys so will probably go down that route.

I used to have a 1967 beetle that I totally rebuiltwith electric windows, solenoid doors etc. I priced up having an alarm fitted and it was over £200 Ithought sod that. The wiring in the car was like spaghetti.
Sooooo....In an afternoon,I ripped every wire out of the car, bought myself 3 reels of wire, and rewired the entire car in few hours..
don't be afraid. They don't come much simpler than a VW Beetle. Theres only a few circuits to wire in. Just remember to earth everything well. The main problem with electrics on old VWs is poor earthing

I've used a VW Heritage loom before, on a 1970 1500. Everything worked first time ex let for the interior light, which I call a win! £250-ish well spent.
Edit due to being distracted by excited 3 year old - a friend is looking at wiring loom options at the moment for his '71, so I'll pass on the Autosparks link. Thanks @grumpynorthener!

I’ve been speaking to vwlooms heard good things about them and works out £20 more than an off the shelf one for the same sort of thing but I believe the whole loom is labelled for you so makes the job even easier! Will post some pictures of it when it arrives.
