Thank you AirSniper, but I already placed an order for a generic Faria gauge.
As far as the Smartcraft gauges. I noticed the Merc Monitor install in the sticky which seems like it's straight forward. I am not crazy about the square monitor but the SmartCraft SC1000 Tachometer seems like a worth addition. Of the top of your head, Dr Honda, would that require the same type of harness (879982T20 CAN harness) as mentioned in the sticky or it's a completely different install?
