Gino:
I used one made by these guys:
http://www.premierwiring.co.uk/index.ph ... 67901-3830It looks like they have a link to eBay to buy. I would recommend contacting them to get the correct one. The one supplied by Spyder was clearly made for a fibreglass car as it has a lot of ground wires in it already.
I purchased the loom from Spyder. It was pretty close to what was needed for the Plus 2. It has a built in fuse block, which can be mounted in the glove box.
The loom is very adaptable because it is not wrapped in loom tape, just held together with tie wraps. I modified it extensively for relays. As it came it would work OK, but relay mods for the headlights are a must and the headlight micro-switch physical location may require changes. The wire colours follow "Lucas" standard, or I guess more correctly BS-AU7a 1983 Colour Code for Vehicle Wiring, which are summarized here. I have not played with Elan Plus 0 wiring, but seeing some of the stuff on the forum it doesn't necessarily follow these standards in all circuits so can be a bit confusing on a few details. I think having a replacement loom that is configured to follow the standard is a big plus, because you know exactly what each wire is meant to do just by looking up the colour.

http://www.spydercars.co.uk/new_project ... rt_6-2.htmNote this is not a Lotus specific loom, but in many ways is an upgrade. A few things need to be modified; for example the turn signal and emergency flashers work off of one flasher unit rather than two units, and I had to get creative to get it to work with the simple dash switch in my Plus 2 and to correctly work with a single dash indicator bulb. I had to add wires for the power windows, two speed heater, electric fan relay, low fuel lamp, and a few other things. It has accessory power connectors so this is not too difficult. Any added wires reference the standard, and any that don't follow the standard or are not needed in the Lotus (i.e. rear fog lamps) are removed. The whole thing is presently attached to the dash and ready for installation, with two front legs to under the bonnet and one leg to the boot and interior. I will be cutting it when I install it and adding connectors as required. I expect main connectors are not included in the loom because their physical location is car specific; you need to move them about depending on the size of the car.
It does not come with a diagram, rather a detailed set of instructions telling you what each wire does and where to attach it. Some of it is a bit confusing, but I think I got through it. This is not a quick or cheep job; I worked away on it through last winter so I was not rushed and had lots of indoor space to lay it out.
Any wires, connectors, relays, wire covering, special tools, etc. I wanted to add to the loom I purchased here.

If one knew all this at the start, installing what you have now would be easy, and I expect you wouldn't be asking about it.
I found having the Uniloom as a starting point was a lot easier in learning how it all works schematically, and more importantly, where each wire is physically located in the car.
