Brought a vs v6 ecotec ute that originally had a getrag manual in it but for some reason he has put a t5 in it matching loom and ecu for some reason I've got no reverse and no speedo. Check other forums and there's heaps on doing auto to t5 conversions but none about getrag to t5 please any help would be great

You have to find out what speedo sender the VR V6 used. What do you mean you have no reverse? Reverse lights? Making sure the switch is there and plugged in is a good start, jack the car up and look around under there..
