C20XE to LET Loom Query

So my plans are finally set in motion and when I take out my C20xe a turbo of some sort will replace it. My question is I have seen a few plug and play ECU conversions that mean I can get a C20Let ECU with internal map sensor but i cannot find a LET loom anywhere at the moment and as usual I want to do a cheapish build.

So what are the differences between the looms and can you use / modify a C20XE loom to run a LET?

The let loom has the vac pipe for the ecu plus amal valve sensor they are hard to find iam having a hard time finding a c20ne loom haha

Is the ECU plug the same? You might be able to get one customised or modiified to suit. Costs start about ?200-250 for an aftermarket ECU loom to be made in my limited experience.
