Auto-Electrician NEEDED ~Urgently!
Discussion
Hey everyone. I’m after some help. So, here goes….
My missus has just bought herself her dream car. A 67’ Mustang. It’s in no-way shape or form a showroom car, it’s a project. She’s the first UK owner having just gotten it registered.
When she purchased it, it ran/drove great. Now, for some reason, it’s refusing to start. We BELIEVE, the car was built as a drag car. So it’s not standard. There a s**t tonne of wiring under the hood, and additional features not found on a standard 67’.
From mine, and her dads knowledge, we both agree that it needs a re-wire. Trouble is, neither of us knows how to do it, let alone where to start.
So here’s the ask. Is there anybody on here, auto electrician or general know-it-all who could help us out. She’s so down about it and I’m really trying to help as much as I can but this is beyond my skills and knowledge. Iv attached some photos so you can get the general gist of what we’re facing.
We live in the UK, near Mold. Close to Chester. If anybody can give us a free quote or any help we would be so greatful. Thank you all in advance.

That looks a lot like it has been fitted with a throttle body that looks like a carb, I think that is what the wiring is going to the ‘carb’ and what the electrical components on it are.
If that is the case, then getting that removed and sticking a carb on it would be a could starting point. Trying to diagnose a system like that, which appears to have been badly fitted, is likely to be a nightmare.

It’s a holly carb, if that helps?If that is the case, then getting that removed and sticking a carb on it would be a could starting point. Trying to diagnose a system like that, which appears to have been badly fitted, is likely to be a nightmare.
You have the battery and air filter connected when you are trying to start it? Battery charged and Points clean and dry? Fuel in the tank?
What do you hear when you turn the key?
Nothing,
A click somewhere,
Engine turns and splutters/doesnt,
It starts then dies after a bit,
A high pitched whir,
That wiring is a little rough around the coil and whatever is on the other inside wing but it's not a tuned up engine just sensible mods for a classic, a rewire isnt necessary but an auto spark will be able to tidy the wiring on the wings up, and make it look more professional.

It looks like a Holley EFI: https://www.holley.com/products/fuel_systems/fuel_...That's EFI as already said. It's a pretty bomb proof system that is hard not to make work if it's all plugged in properly.
You should have a hand held controller for it somewhere that will give you diagnostics, when you're cranking do you see the injectors firing? If so it's something on the coil side so start there.
Holly website is very good for manuals etc. which include wiring diagrams and connector details. You can get them from the Holly website linked above
Given the Holly system comes with a reasonable loom you should be able to gut and replace all the chassis side wiring without too much fuss and retain the Holly loom and related to create something quite reliable.

Employ this man - he has cured the problem.Just a quick question OP - do you have any wiring diagrams for anything you have on your car? I'm an auto sparks, and that looks like a complete mare to try and worth through. last time I did a job like this, it took hours and hours, (40 +) and we did it on an hourly basis. This will be the same - but probably more complex.
One option is getting a local race team to design and make an engine-only loom for it. Given the state of motorsport, and especially during the off season, you've got a lot of people experienced at one-off troubleshooting and fabrication with empty pockets and idle workshops. All the better if it's on a car which is interesting to petrol heads.
Job's a proper pain and not so many will want to know it
Strip car interior, remove all wiring, make a new loom and fit, test and rebuild interior
60 Hours @ 40 Pounds +/Hour should cover the job
Anyone charging less than 40 Pounds/Hour is scraping for work due to having a bad reputation - don't use them - you get what you pay for
Plus price of cable, connectors, fusebox, relays and holders, tape, sleeving and clips - approx 200 to 300 Pounds
Labour + Parts = 2700 Pounds
VAT = 540 Pounds
Sum Total 3240 Pounds

Doing it on the body loom(s) would be a huge and very tedious job. But the engine loom is self contained and usually much simpler. If the problem is with the engine loom, getting a new one made is not likely to be prohibitively expensive.The problem with "project cars" is that they are often one bodge on top of another, and on a 50 year old car, that's a lot of bodging.
IME, to make a reliable classic means to dothings properly, strip out ALL the old crap, start again. yes, it's expensive and time consuming, but consider than one bad connection means the car breaks down or is unreliable and your classic dream can soon become a nightmare!
Luckily, an old bit of US iron really isn't complex electrically speaking, so i'd recommend getting stuck in, and lots of parts are available from premade harnesses to harness kits etc.
All 'lecy does if flow from + to -, so really, if you look at each circuit at a time, it's not actually very complex at all, it just looks daunting at first!

The thing in your last pic looks very much like this type of isolator - often operated by a hidden switch inside the car to isolate the battery.

It looks like an old school starter solenoid.https://www.caravansplus.com.au/images_tiff/2012/1...
Really though, from the pictures, it would make a lot of sense to have someone competent look at it, and rewre as necessary....as it does look a "bit" of a mess overall..
Like a lot of a mess.
Can't help as to where to go to though, but there will be shops out there who will be able to do that sort of thing.

You can get a ready made loom here: https://www.americanautowire.com/shop/classic-upda...
This is a modern take on the Mustang loom and can be installed by almost anyone because it comes with comprehensive instructions: https://smhttp-ssl-87263.nexcesscdn.net/media/prod...
American Auto Wire also sell a 'restoration loom' for anyone who insists on period features, and would prefer not to have to suffer the annoyance of a modern reliable fusebox etc.
