Hi guys, Looking at buying a 2nd hand GTS Link but the seller doesn't know anything about it or whether its for a R33 or R32. There is a chip with the link logo on it that says GTST then has the number 050406. Other numbers seen on the unit are GTS293, also a sticker that says 2382 10925 ASL 28/3/06. Anything I could find out about this unit would be great!! Is it G1 or G2 ? If it is R32 compatible will be using it with a RB30DET in my R32 with an R32 loom. Thanks Jimmy
