Hello
To save time and not bore anyone, I'll get straight to the point and tell you what I want to know:
I need to know which is the most complete wiring harness for a Defender 300 TDI.

The last question is whether anyone can tell me where I can find the label with the code for the engine harness and the main harness.

Perhaps the best answer would be to provide me with a link that has all the harnesses with their functions and connectors.
The LR Workshop diagram is very useful but the information is insufficient for what I need.

In case you're interested, I have a Defender 90 (year and model 2000) It comes equipped with a few things including air conditioning, radio, rear defogger, rear windscreen wiper.

What I want to do is add various options that aren't in the car. But I'm going to do it as standard. Electric windows, electric locks, third brake light and alarm centre (preferably A 10) are the initial goals. To avoid improvisation and splicing, I'm thinking of changing the original wiring harness.

I think that in this case, the best approach would be "the more, the better". I believe that having the most complete harness possible is useful, even if there are connectors left over. I'm thinking of leaving it available to add abs, traction control and an EGR valve at a later date.

The most complete harness I have is YMC002503. But it doesn't have ABS.

If anyone would like to help me, please ask me what you need.

From what you posted, I still see you still needing some add on aux wiring. Most of what your listed are relatively simple easy adds with not really spicing into much. Depends on the list of needs.

This is a good start..

LR used dozens of slightly different harnesses and part #s depending on the year, country, and features so it’s difficult to pinpoint one. Many of the optional features required auxiliary harnesses which makes it even more complicated. You may be able to determine what you need using part catalogs like LRWorkshop but the part descriptions are vague and the harnesses are often NLA anyway.

I’d look at what Autosparks offers. Their main harnesses integrate several optional features and they offer aux harnesses for the rest.

I like the post-97 spec harnesses like I assume the OP has. I think autosparks only sells the old rubber and bullet style pre-96 type.
