Thanks

You will have to remove your loom and then have one made by copying it. This company will do it for you.

Thanks

As I understand it the loom on a 2.9 efi is a separarte part of of the main loom - wonder would one from a Granada or a Scorpio suit?

I also heard that an EFI pinto loom is very similar 0- just a couple of connections short - that can be added in.

Best

S Series do get scrapped occasionally or maybe you can find one from a 2.9 Granada?
Wouldn't fancy trying to adapt one from a four cylinder engine.
Is yours "toast" or missing?

Where are you going to find one from a Granada or a Scorpio now? They were just worthless old bangers that were scrapped under the various scrappage schemes. There is only one Scorpio on Autotrader currently for sale at £3K. You could buy that, take the loom, hope that it fits and then sell the car on, but that's a lot of hassle for a 30 year old loom that might be total crap. It's far easier and cheaper to get a new, custom made loom, which you know will fit, work and have a guarantee.

I'd start here :

The engine wiring loom in my 35 year old TVR ( and those in many others) is still quite serviceable, can see no reason why one from a Ford of similar age that is being broken for parts shouldn't be?

Why would you when there are specialist companies that will make up a custom fit loom for you brand new, with a warranty?

Why would you fit ancient parts from another make of old banger that might not even fit or work, when there is a superior alternative?

The same reason you hunt for any other old parts instead of having them remanufactured.

Cost ?

Why not fit ancient parts from one old banger to another old banger, do you consider all cars over a certain age as old bangers? wink

"Justo" has gone a bit quiet, lets see which option he takes? He didn't explain whether his is missing or whether he has something that could be repaired or duplicated smile

How much is a 30 odd year old loom then? What if it doesn't fit? What if it has been butchered in the last 30 years, many times? What if it doesn't work properly?

What do you want your TVR to be? A well-maintained classic, or just an old banger kept on the road as cheaply as possible? When you see a car with never-heard-of-the-brand tyres and a bottle of supermarket brand oil in the boot, you know to walk away.

Would you rewire part of your house with some 30 odd year old wiring that your neighbour's electrician has just put in the skip? Would you buy a house like that?

Read the thread.

I posted about where to get a brand new, custom made loom made, with a guarantee, and people then ignore that and start posting about getting non-existent looms from 30 odd year old Ford Granada bangers, that probably won't fit and will be total crap, but might be a bit cheaper to buy, but certainly won't be in the long term.

Every time some sensible advice is given, someone has to post a stupid alternative.

If someone can get a second hand loom for a few Bob and do a few continuity tests Bob’s your uncle.
Why fork out on a new loom on a car that might only do 2000 miles a year if a second hand one with mostly the right connector blocks is already to go.
Your suggestion isn’t a bad one but the later suggestion from someone who’s had far more experience of these looms than you have probably ever had is hardly stupid now!
You just can’t be contradicted can you biggrin
Calm down lad wink

Strangely there is one in my garage. A couple of issues, one of the plugs has been chopped to do a repair but could easily be grafted from your existing loom. Second, I’m on the other side of the world tilll March, but let me know if it’s any good when I’m back and you’re welcome to it at nominal cost.

I have a loom that has been seriously hacked about with the main ECU plug and a few other bits having been "borrowed" but may have the plug Ray's one is missing?

Justo, is your loom missing, fire damaged or totally kaput?

Guys

Sorry - I have been away from the computer. I take on board all the comment on new looms and old looms. My situations is that I am transplanting the S3 engine into a 3000m.

I have part of the loom. Someone has cut the loom after the 8 pin connection that is the injectors, tps, map?, etc on it.

I have also discovered there are no MAF sensors on the engine so I may consider going DTA ecu or other

Thanks for all the comments

If there are no Mafs is it a catylyst engine with Lambdas?

From memory it’s just one of the injector plugs (junior timer) that’s been chopped so shouldn’t be too difficult.

The only complexity may be that there is a diode hiding in the loom and when I’ve looked at this in the past there is an error in the original wiring diagram in the Steve Heath book, but somebody has redrawn a corrected one.
