hi every body i hope some one can help me im wanting to fit two after market gauges 1 oil pressure and 1 temp when i install these gauges do i have to run the origial sensors for the computer or can i discard of those wires thanks
It's best to keep the original wires, since the oil pressure switch does report back to the ecm and the temp gauge (I'm assuming you're putting a water temp gauge in), there are two separate senders for that, one goes to the gauge and one goes to the ecm. There's no reason you can't leave them both hooked up. But since there's a water temp gauge there already, why hook up another one?
