Chubb

Hey fellow third genners, I was considering converting my base sport coupe's dummy/idiot lights with Intellitronix's digital gauges. My question is, would I need more than the oil, water, and the speedometer senders. I know the fuel and rpm tach can use the existing harness but I was just wondering if anybody had some info for me. Thanks to all replies. Here is what I want for anybody that wants to see a pic.
