2.0 Ltr Zetech Engine Loom

[Pete Mar]

Gent,s

 

I was just wondering if it is possible to use the standard Zetech engine loom on my Zero or do I have to buy the GBS loom which seems very expensive? I'm planning to use the Emmeraled ecu and the GBS Plenumb on my build.

 

Your thoughts would be much appreciated.

 

Cheers

I have the same set up as you. I ripped out the engine bay loom from a ford focus at my local scappy and used this as the basis of my engine loom. It was the only way i could find the connector to mate with the injector loom on the engine. Much cheaper and more satisfying building my own than buying one. Depends on you appetite for wiring.

 

I have a wiring diagram and pin-outs in my notes at home if these are of any use.

Hi sounds like a good solution, did you use the GBS main loom in your kit? and did the Focus loom take a lot of modifying to get it all to hook-up?

 

What type of focus did you get your loom from, will it need to be a 2.0 or will another engines loom work?

 

If you have the wiring diagram and pin outs that would be great.

 

Thanks for your help.

Yep i have the main GBS vehicle loom.

 

Any Mk1 petrol focus should be ok, 1.8 or 2 litre ideally. Its good because it gives you most of the connectors you need for elsewhere on the engine (crank position, coil pack etc). You'll still need to source the deutsch connector to mate onto the GBS loom, and the connector for the emerald ECU normally comes with it (+ water temp and air temp sensor)

 

Thinking back, I chopped the loom ont he focus where it enters into the passenger comparment under the off side wheel arch and this left a few of the wires a bit to short for what i needed so had to extend them. I ended up stipping the whole loom down and building it all back up again, adding extra wires for the fuel pump, altenator, oil pressure sender etc.. and getting lengths correct - doable but not straight forward.

 

I'll did out my notes, type them up and send through.

Hi

 

can make up loom as stated above, plug, with fly leads, to plug into GBS main loom is available from them.

Here is the wiring diagram and pin outs for the engine loom I made.Hope this helps.Dave

Hi

 

dctough, does your wiring work?, I can see some differences to info on GBS web site.

 

e.g

 

pin 11 main loom connector you have as tacho, GBS have this as alternator warning light

 

pin 10 you have as oil pressure, GBS state water temp.

 

pin 9 you have as alternator light, GBS has oil pressure

 

there may be other connections that do not match but that was the first section on your list

 

Am I missing something?

 

Regards

[Guest dctough]

Yes it all works. GBS hadn't released any of their wiring info when i put it all together, so those were the pins I chose for each function. For the functions you point out there are a handful of wires that go from the engine link connector to the gauges connector. It doesn't really matter ones you choose as long as you are consistent at both ends.

Just use everything from the donar car, loom, sensors, ecu, immobiliser. Stick on a GBS plenam and bobs your uncle. Fuel injection with full immobiliser and OBD and mine cost about £50 (plus the GBS plenham)

Hi

 

appreciate if the info isn't there you must do something.

 

any help on forums is better than none, just feel that we should make clear, and I now realise I am as guilty of this myself, if the advice we are offering is our own solution to a problem, or a standard (GBS) solution to a problem.

 

might seem inconsequential, but I can recall a number of forum members who have wished they had been aware, so they could make their own judgment before using said advice.

 

anyway, like dctough info, a lot of time has gone into them, and easily converted to standard.

Thanks for the advice, I'm thinking I am going to go down the same rout as dclough. The info supplied is perfect and makes the whole thing a lost easier to grasp, I.m off to the breakers this weekend for an engine loom.

Also guilty at times. I have solutions and work-arounds dating back to monocoque times. Looms have changed. 2B, superspec have come and gone. Zero is current. Disgraceful that the same or similar electrical problems are still happening because the GBS electrical side does not keep up. I know they have to order '500 looms to design XX' for commercial reasons and these looms will be issued for the next 3 years. But updates, amendments to the instructions should be an active priority so that anyone buying should have all the 'errors' listed and the official GBS solution in hand when they receive the kit. Electrics seems to be the main area of problems for most kit manufacturers looms. I would recommend using a seven loom from one of the electrical specialist suppliers. More likely to be right first time.

In the meantime builders should be aware that there are errors, detail instructions missing for some sections, amendments needed, etc. It might be helpful to have a pinned thread contributed to by current builders of these errors in the current GBS loom and their official fixes.

Solution givers should add a note to their posts saying if their answer is the official solution or a self invented non standard work-around.

Hi Longboarder

 

nice to see some agreement with my thoughts.

 

however the current GBS loom is a foolproof solution, yes, at a cost, but there are none of the issues of previous offerings, from GBS and others. I would put it against any out there and I include the likes of Caterham, it is totally plug and play, as long as you buy the two sub looms, to suite engine and dash.

 

Pete is planning to make his own engine sub loom, and can certainly see the advantage in terms of cost.

 

GBS do now provide update info via their kit spares download section.

 

they will even design, and if necessary, build, bespoke looms on request, but I'm sure it won't be as cheap as doing it yourself, just less hassle.

The zero loom is plug and play.

About time too. This has always been a weak point. Now resolved.

Am I surprised? Yes and no. After the years of the VG loom which had faults from day 1 till the end and was less than satisfactory. The continuous stream of electrical questions suggests ongoing uncertainty amongst builders and there are zero builders amongst those having problems. Is this due to them doing their own thing with electrics, either because they want to or because they can't afford the GBS offering and have to or some other reason? It's easy to assume that loom problems continue.

GBS have been improving many aspects of the zero for a couple of years. There has been an excellent programme of steady development to chassis, running gear, drivetrain with particular emphasis on improving the builders experience. I should not be surprised that the GBS progressive improvement policy extends to the electrical systems on the car. More should be done to clarify the cost benefit trade off to builders if is is expensive. Perhaps some of you successful zero builders should do more to promote the full loom and sub looms on the board as electrics are a subject that seems to leave so many new builders trembling in fear. Many would spend on the looms rather than flash alloys if they realised the saving in build time and frustration and the more professional finish possible.

the plug and play loom is really expensive though and when compared to the loom from someone like premier wiring I don't see why you would buy the GBS loom
