Good morning, do I need to use your RPM signal adaptor with this tach? This is in a sand rail with a 2002 Honda with stock ECU?

Asked by: Chuck 1944
Most 2002 Hondas have a dedicated Tach Test wire, typically blue, that will drive our tachometers. You should not need any adapters.

I have this tach. Will this support a shift light? If so which one? Does it simply plug into the tach? I am aware that I can purchase shift lights that are independent but would prefer to benefit from my already installed Auto Meter 233907.

Asked by: steamer97
Thank you for your question. Yes, this tach includes an optional shift light output. It will connect to any of our shift lights, such as #5334

How do I remove the case for this product to cut the wires for 4-culture engine

Asked by: Streeter81
Thank you for contacting us. Any of the 5" AutoGage tachometers with Memory, like the 233907, actually use the buttons for calibration and do not feature the wire loops to clip. Here is a direct link to the instruction and in the top right you'll find the details on setting the calibration with buttons:
