The green wire with the black stripe, under the center console........ Options

[toon1]

Shouldn't it corrospond with the green wire with the black stripe on the wire harness that plugs in to the back of the relay board.

Also, isn't it for an oil pressure gauge.

My car did not come with a center console so this wire was taped sto the wire harness at the connection in the engine bay


Thank's, Keith

Like Andy says, the green-red wire is intended for the oil pressure idiot light. But you have custom gauges apparently. It goes from the oil pressure sending unit, to the relay board pin #1 (engine side), out the relay board pin #5 (body side) and up the center of the car to the gauge cluster. So as long as you connect it to the appropriate sending unit (the stock one probably won't work) it should work fine. You'll lose the idiot light function this way, but maybe your gauges don't have that anyways. I don't know. You'll have to figure that part out.

I don't know what the green-black wire is. That is the standard color for 911 oil temp guages, but 914-4s don't have them, or that wire as far a I know. I had to add one for my 6 conversion, along with a pressure wire. Your setup is going to be custom it sounds like.

Hopefully, you have a copy of the 914 wiring diagram. Porsche manual, Haynes manual, electronic copy, whatever. Study it for a bit. It's not that hard to figure out, these cars a simple!
