Sorry DaveW to go off topic a little but as i promised pics of the GMPP loom and the problems i see that the end user has to deal with.

harness is just so long every where that it is just a mess.. take a lot of time and effort to fix up - and why it maybe cheap but i would want it to pretty much fit perfectly




A few more pics





they leave a adapter plug so it can suit either map sensor... good for multi fit but just looks dreadful

and lastly the looms are desgned for manual so you need to buy an auto computer as well and it is a big ugly mother along with an octupus for a harness








along with this mess still had to add in wires between the auto to manual, supply your own terminals (which arent easy to get) for the bulkhead plug and supply your own plug and termials and wire in the Alternator as it was setup for the US alternator but a VE one was fitted.

Also another thing i remembered , cause we have an auto then we need to plug the speed sender wire into the auto from the TCM , which means the Engine ECU now has no speed reference into it and as there is now no speed output wire as the TCM doesnt cater for this.. will either require some splicing in or may even need a booster box once spliced in.... All this is catered for in the aussie style modified looms

these are just my opinion , but when you are paying good money for a harness and ecu etc.. you would want it to be able to do all and fit nicely pretty much straight up .. not need you to remove and shorten nearly every wire in the harness.

I am not preaching for all cobra owners to buy looms through us ,but more of a warning for what you are getting into. Most of the harness guys here in Asutralia suppl y a fairly snug fitting loom to the engine and just the fuse relay area differs and i would say they are all better than one of these harnesses.

and DaveW remember to call me when you are back and we will see if we can sort that mess out you have of a Kit. If the loom matches the ECU and the ECU partnumber is 12597121 then it is an easy fix to get cruise and ABS/Traction going... its just whether you want to part with the folding stuff to pursue the ABS/Traction but the cruise is not that expensive.

It's not hard to shorten and tidy up a wiring loom. A good soldering iron and some heat shrink tube and your on your way. If you need some pointers on how to make a reliable invisible wiring splice let me know and I'll post something.

Cheers

your missing the point.. i know it isnt hard.. but when you pay good money it should be done for you .. not pay money and then still have to fix it up... its like paying your spray painter to paint your car but when you get it home you still have to cut it back and polish it... it isnt hard but it should already be done for you.

Thanks for posting those pics. I see now what you mean and your point.

As Mike said its easy to shorten a wiring loom. But not everyone has the soldering skills so could be an issue for those that expect not to have to touch it.

To me buying it from the US which works out at half the eagle auto price is a pretty good DIY option if you have some basic wiring skills.

Its just the emissions that i worry about.

I think what GM has produced is pretty good. You've got to remember that it's a universal loom and potentially has to fit a lot of different styles of installation. These motors are going into all kinds of vehicles and not all with the standard intake setup.

I think most of the people on here are DIY types. You wouldn't even contemplate taking on the build of a Cobra without having some skills or desire to learn desire the skills to build one.

It comes down to price. Yes, a custom installation is nice but how does it compare in price to an off the shelf loom you can plug in yourself? I imagine you start with a donor loom to wire up a car. That's what I did, I bought a new Commodore loom from Holden for about $450 and then stripped out all the unnecessary wiring and shortened it to suit my application.

Most people seem happy to mess around with suspension, welding, fabricating and bolting things together but look at wiring as if it's some dark art. In the days of just a carburetor and an ignition and charging system to get it running most would have a go themselves. Suddenly EFI is here and seen as just too hard. In reality it's not that different. If you read the books and take the time to understand what the components of a system do and how they work together it's not hard. There are plenty of wiring diagrams and resources available for anyone wanting to have a go themselves. Take the challenge to learn something new.

I think it might be worthwhile to start a thread on here explaining the basics of how an Electronic engine management system works.

To shorten a loom you don't even need an understanding of how the system works.
All the plugs are different, the wires are different colours. Use a camera to document what was where and have a crack.
Just ensure your joins are well executed and insulated and you can't go wrong.

Mike,
I have a Gmpp controller kit for the LS3. On the first trial fit you can see how it needs to be tidied up, but as you say it is not hard and to be honest it allows me the opportunity to do a bit of custom work.

The kit includes the loom, all sensors; Fly by wire Pedal, ECU with a tune that should see it run ok. All of this for $1050.00 delivered to my door.

I think it is about time GM have understood the market and provide the tools for the DIY guy to have a go. I am surprised the smart operators have not grabbed a hold of this and used it to their benefit rather than dogging it.

That's fantastic value for money Phil. I reckon I did mine on the cheap but if that had been available when I did mine it would have saved a heap of research and money.

Cheers

I used a Painless performance harness and found it to be relatively straight forward. It comes in 2 different lengths depending on what you need, Mine had DBW as well, Hooked it into the original body loom, Crossed my fingers and nearly crapped my pants when it started and ran perfectly, Did'nt expect that! Not all rosy though, check engine light was on and will take some sorting for that to work properly.

That would be great.. Thanks

A bit of modesty and a lack of sarcasm would do you and your siamese twin the world of good.

You need to pull your head out. I said yes cause I think it would help others out seeing as there is a lot of discussion on shortening looms. Sounds like mike has something done and would be best to share with all. But once again it only enforces our belief that if we don't help or say something to your liking you start up with the criticism. But of course you know best.

[Zedn]

Measure, cut, strip ends, thread on heat shrink, twist, flux, solder, slide heat shrink over, heat, Your Done!

I can understand Gav's reply, An auto sparky (or someone working with an auto sparky) replying in the way you did, does come accross as fairly arrogant.

But I will give you the benefit of doubt and think you honestly ment your first reply the way you have explained above.

Easier still...get new pins that go inside the plugs...shorten the wires , crimp on the new pins and put them back in to the plug. The pins are available at good auto elec supply and you can buy crimpers and pin removal tools from Jaycar for not much $.

If my first reply was was being arrogant or taking the piss cause i am a sparky then that means that Aussie Mike's reply about it was being just as arrogant or a very cheap shot at me. Specially considering that he posted it straight after my post, but once again everyone has missed one of their own saying something about us and focused on the negative from the non cobra owners.

It was meant as a help for others as Mike made it sound like he had something from previous that may have had pictures... very easy to say strip this solder that but some of the soldering joints i have come across in the passed you would have thought "what the F%&K did this to the wire". They certainely would have been better of with a twist and tape.

Rob, none of those places would have what would be needed to shorten these harness with new pins etc.... only Jaycar would have the solder and heatshrink. The pins etc. are very specialised and 99.9% of autoelec's out there wouldnt have them.
I think the plugs/pins you are thinking/referring to are the Narva white plugs with the normal brass or silver crimp terminals as used in relay holders.. none of that is used in these harnesses. They are all the delphi style plugs which have very small terminal and most need a special crimping tool.. especially the ECU terminals as it is near on impossible to try and just fit the wire and terminals into the ECU plug with out them.

Please, I dont want to get into an argument (I know that may suprise some in here)
All I was trying to say that for someone in the game saying they would like to see how it is done by someone not in the game, comes across as being a smart ar$e.

Yes I know that Mike is in telecomunications and really does know his stuff, but working on car electrics is not how he puts food on the table.

I would just as happily see a tutorial from you on how it is done properly, but I understand that when you do car electrics as a job, the last thing you want to do is talk car electrics after hours.

Mikes offer to do a tutorial, I have no doubt is honest and genuine (that is just the type of good guy he is) and I reckon he will be out in the shed this weekend doing a wire mod and taking pics along the way. (that is if he is in Australia and not O/S working)

And I doubt Mikes reply was a cheap shot at you, He would have simply been offering to help.

[Doubledip]

I dont want to be in an argument either, but is it acceptable then for someone to post to some one in the game "would you like to know how it is done" ????


if i can take his comment to me as being genuine and helpful then why do i get percieved as being a smart arse when i make mine and say yes post (as it will help others)....

I doubt the post was directed at you, more likely at the people who have already purchased the wiring harness that is too long.
