Guys, i am trying to connect the speedometer and rev counter of a Toyota GT4 (ST205). Now the speedometer is ok i managed to get it work. But when I come to the wiring of the tachometer its like has a negative effect. It's like it is trying to move downwards when i give it power not up the revs. Can someone maybe help me on this.
PS I dismantle the cluster and separate the rev counter from the speedometer.
Also can be the case that the rev counter of the ST205 is opposite (- or + signal)...i am not that much into electronics but i can manage some things.
thx
Ramon
