Why not just buy a single plug Pred and get a single plug quicky loom spliced to yours, the single plug Pred is cheaper, and is proven to work on a R already, the 3 plug as far as I'm aware isn't yet
You'd still need to change coil pack and maybe a few sensors for the inlet, possibly icv set up, but youd have to do the same for a 3 plug loom
Be easiest to find Simeon breaking a single plug quicky, buy the loom, full inlet and tb, and the coilpack
Martin spliced mine for me, but Ryan should be able to aswel
If you get me some pics of all sensors on inlet etc, post them in here well have a look, i bet youd only have to change one or 2 and coilpack if that
