Been having a look online at 300tdi conversion parts and found a suitable engine/box combo ,I did consider whole discovery and may still do ,but here is my dilemma

At present have a built chassis and body ,no electrics at all ! and have decided to fit 300tdi engine and box ,at present I have no idea which loom to fit ,is there an easy option series petrol or diesel better ? Is it worth getting 90 loom ?

As long as 300 is non electronic version diesel series will be fine , some add ons and mods for glow plugs but all quite simple.

Thanks for reply
