kaylz_555 Posted October 15, 2010 Author Posted October 15, 2010 (edited) found this if anyone is thinking of getting a Tachometer (Shift light) gauge only place i could find anything about this. ( wrxtuners.com ) hope this helps someone. Most people will say that this gauge is useless. When ever I go to the track it is nice to concentrate on driving the car down the track without having to look at the center gauge. When you learn your power curve (you know when you stop producing power) so it is time to shift up. You can set your shift light at that point of your RPM’s, so the shift light tells when to shift. So you do not redline from excitement and you are racing to your car’s to the best possible limit for great run times. Mount the gauge after you remove your stock gauge cluster. This will make running the wires for power, Illumination and ground for the tachometer and all other gauges easier. Wiring This is how I connected my wires and have connected them for years there are other ways but this has worked the best for me. First DISCONNECT YOUR NEGATIVE CONNECTOR TO YOUR BATTERY! Now you will want to follow the color code provided by the instructions of your manuals of your gauges fro m the back of the gauges to the following on your Subaru. I ran three spliced wires from the back of the clock pod. If you look where the connector to the back of the clock runs you will see they are actually labeled. You may cut the tape and tie wraps to gently pull more slack in the wire to help your splice job. Accessory 12v switched is the Yellow wire with Blue stripe Ground is the solid Black wire Illumination is the White wire with Red stripe Run your spliced wires to the central point of where the gauges will be mounted. Splice them together accordingly with the wiring diagram per the gauge brand. This can be done with a connection block or wire nuts. The tachometer requires a sender to be spliced take the corresponding wire for the tachometer and splice it to the wire attached to the green clip that was attached to the stock gauge cluster that is all the way to the right above the speedo side and splice it to the solid blue wire which is the sixth wire to the left. When you are finished splice correctly put everything back together, re-attach your negative connector on your battery and enjoy your gauges. Edited October 15, 2010 by kaylz_555
