TD5 complete engine harness - install tips??

[simonmelb]

Hello,

I'm slowly ticking off mid life preventative maintenance items on the TD5 and I came across a new old stock genuine LR complete engine harness on eBay - won and delivered for $120 :)

It's unopened and was made in 2006 - so has to be better than the one under the bonnet.

Has anyone replaced theirs and are there any tricks or tips?

I plan on doing the starter contacts and injector harness at the same time. I was just going to reinforce it with some Tesa 51026 high temp tape and install.

Any other suggestions welcome.

That's a good price :)

Although you probably know make sure you have the correct harness for your car, there are 6 different part numbers depending on VIN and region.

Mine is LHD and went in quite easy cos the main part of it is along the RH side of the engine, on a RHD the steering column might be in the way a bit, i know that the fuel cooler was unbolted to be easyer and important is to cut the oil temp sensor wire in the RH side before you remove the old harness and let it there then hook the new oil temp sensor to that wire and pull it to the other side behind the engine if you see what i mean.... you'll be amazed but just by replacing that harness you'll feel an improvement in the engine behaviour cos all the contacts in the old sensor plugs are "tired" and low power 5V + PWM signals are sensitive to contact strenght... at leats that's what i felt after i replaced my 10 years old with new also as preventative maintainance

Thanks for the advice sierrafery - I was hoping you'd reply. :) I hadn't thought about a running improvement as my Disco runs very well but you never know. That's a good tip about easily getting the new oil sensor wire easily around the rear of the engine too. I'll probably replace the crank position sensor while I'm at it, as that's original too at 292k km.

It's not a hard job, but it helps to take careful note of how it is routed before you remove the old one, maybe your camera phone will help. Sierrafery is right you will likely see a running improvement. Well worth doing good luck.
