Hey guys! I have a '94 TT Zed. The speedometer has failed in the gauge cluster. All other gauges work perfectly - including the trip meter and odometer, so i know there is a speed signal getting through from the gearbox speed sensor, sub harness to the dash ok. My question is, can i keep my existing '94 cluster (which from my understanding has different connections on the back and has no stock boost gauge on there), while replacing just the speedometer gauge from a S1 cluster and connect straight up? ...or do i need to scour the bowls of hell to try and find a working oem speedo out of a '94 model Zed from somewhere to get to work in mine? Hoping someone can help so i know where to look, and thanks in advance peeps!
