Wiring Loom for 200tdi... which will work?


Recommended Posts

Hello,

I bought a LR 90 with a 200tdi from a Disco, sight unseen. It arrived and on the maiden voyage (1 mile for diesel) I had an electrical fire. It looks as though every wire from the firewall down to the starter is a bit crispy now. I'm yet to pull it out of the dash to see how bad the damage is behind the dash itself. I'm resigned to having to replace the wiring with a new loom.

I've searched quite a bit and it looks as though there is a lot of interchangeability from different engines and years etc. What I haven't found is a comprehensive list of part numbers for looms that will fit my application. The truck itself is an 84, I believe the engine is from around 90-92.

Can anyone here suggest a loom that's fairly common to fit my purpose? Thank you all.

the 2.5TD engine loom is the same as the Defender 200tdi engine loom, might need to upgrade the alternator thick brown wires if your alternator is bigger than 65amps, otherwise a direct swap.

try Autosparks engine loom & they can supply a complete new dash/main loom too use the drop menu to ensure you order the correct loom by chassis number.

if you can find a 2.5 n/a diesel engine loom [LR part number PRC4021] this can be used one a 200Tdi engine instead of a TD loom. the factory fit 200tdi loom is PRC6082 with air con fitted or PRC6061 without air con, these should help you find a suitable engine loom.

or if you feel really adventurous you could build your own engine loom using the correct size/rating cables.

Yeah it's been enough of an adventure buying a truck that caught fire on the test drive! :D

I have a relative that's very handy with wiring etc. I'll run this idea past him and see what he reckons.

Another question that betrays my ignorance: How do I determine the output of my alternator? Also, am I correct in thinking that I'll need two main looms for this? The engine and the "body" loom?

Thanks guys. I've got a good friend (retired civil engineer and general fixer of anything) who says he'd be happy to re-wire the 90 for me. I'll get it to his shop and report back here with my results.

depends if the main aka dash loom is badly damaged, you/mate may be able to make suitable reapirs.
