It is not really as difficult as you would think. If you rip out the entire standard loom and start to look at it you will find a lot of the wires are not used (they are there to run functions on the LandRover that the loom was made for) There are two connectors that link the engine loom to the body loom. One of them has two fused supplies and one ignition switched supply, the starter solenoid drive and fuel pump feed. The other does the temp sensor, Oil warning light, alternator, otter switch and stuff like that.

Who are peoples recommendations for fitting a new loom to an Omex ECU and removing all the redundant Lucas stuff?
What sort of costs are involved? PM me if you like
Get a half loom from Omex and make up the rest of it yourself. I would allow about a hundred quid in parts (it's surprising how quickly the cost of connectors, relays, fuses, wires adds up). I would allow about a day's work although no doubt a professional would do it a lot quicker, I spend a lot of time checking and testing as I go.What sort of costs are involved? PM me if you like

Fancy a day out in sunny Durham Peter 
Thanks for the replies. I must admit though I would not be confident doing it myself, I know my limitations and feel it would be a step too far.

If you're planning to install and set up the Omex yourself it would be a good idea to know exactly what is going on inside the loom. If not, perhaps the person who *is* going to do that would be a better person to make up the loom.
Completely agree with Pete, I have a schematic and loom drawing for my new loom, due to the fact that I had a hand in drawing it!
Had my loom made locally, and armed with the drawing,am now completely confident to deal with any problems(that shouldn't) arise.
For a standard system, there isn't actually that much in the loom.

It also gives you the opportunity to rationalize the colour scheme (if you can see colours 
) 
It is a lot cheaper to just buy pins for the connectors and get manufacturers connector bodies from the scrap yard (they can also be better quality than the oem replacements).
I would not crimp cable joints together, far easier to make proper connectors to join looms IMHO.

Are you planning to install the Omex yourself? There's no reason why not if you have a basic electrical skills and a general understanding of how EFI works. Armed with that you should have no trouble making up the loom (the half loom from Omex comes nicely labelled with instructions what to connect where) and all you need to do is cut, crimp, heat shrink and loom it.

The omex is already fitted, but it's patched in to the old loom. I knew it was not very good from looking at the excess of wire around the rocker cover on the offside, but yesterday I had the plenum off and the nearside was If you're planning to install and set up the Omex yourself it would be a good idea to know exactly what is going on inside the loom.

To paraphrase the Brian Clough quote which has been revived this week "I wouldn't say it's the worst loom in the world.....but it's in the top one"
It's in the darkest corner. If lookng through from dash side( if it's out) if you go to the fare left bottom corner you should be able to fnd it and the rubber gaitor there. Engine side it's tucked right down at the end of the nearsidw rocker cover proberly behind some pipes etc but you should be able to follow it to where it goes through.. Sorry crap typin g done it on a phone

also forgot if you take the glovebox out and got to the fare right corner of the now huge hole, you should be able to see/feel the loom run around the back right hand corner and where it goes through to the engine bay. as it leaves the glove box area about a couple of inches at most It turns and goes through to the engine bay.
I may have some piccies will have a look later for you.
