I am currently converting my xr3i to an rs turbo engine,

how do i go about converting the wiring loom from mfi xr3i to mfi rs turbo

the xr3i wiring loom/fuse box is still in the car with the engine out
i have a complete rs turbo fuse box/wiring loom

can the wiring looms be pieced together?

does anybody who has done this before?

the local auto electrian didnt have a clue how to do what im asking of him, any help with this would be a big help, as the haynes manual doesnt cover a lot in detail
