Hello and thanks for the add!!! I started a swap on my 98 Ti, I am mechanically inclined and the engine is already in, but I ran into a small dilema and maybe can help. I've read that I can use the driveshaft out of the m3 for it but once installed I noticed that there is way too much spline showing on it, is this normal? and also, my m3 donor is manual and has a 3 round plug harness, my ti has 2, does anyone know what the 3rd middle plug with 4 wires is for?
