So I've researched the past couple hours and I haven't found out much bout the wiring for the oil temp and pressure besides which wire goes where. So my question is where is the best location to run my wires to through the vent area. I have megan racing v1 gauges and to me the wires seem really short to reach a ground or the sending unit. Also do I need some sort off line for the oil pressure sender? Sorry but I'm confused. First time installing gauges so go ahead and flame away
