Wiring 1600 GSi into 1200 SPi, help please

[RSTChris]

Hi all, im currently converting my 1200 single point to run a 1600 GSi engine

The wiring is doing my head in with the old ECU, do i have to unpick it right through the bulkhead back to the ECU then start again?

I saved the full GSI wiring from under the dash, would it be easier to cut my loom out and rejoin the GSI one in, would this work? Im just thinking about the injection wiring side of things?

Any guides tips or help appreciated, cheers :thumb:

Leave the spi loom in place, its too much of a job to remove it.

Just join the 1600 engine loom to the spi car loom.
