I would like to install additional gauges; oil pressure, oil temp., volts, etc. in our TiiCo equipped '88 GL.   Thinking VDO or AutoMeter.  The thing that I am not sure about is how to handle the senders and wiring (for press. and temp.).  The senders I assume would be those for a golf engine but what about the wiring?  If I use the senders and normal wiring intended for a Golf and simply splice-in additional wire length, do I upset the accuracy of the gauges due to the add'l wire length?
Any ideas?
