I found another speedometer from another member on here, so I'm good to go for that.
Can anyone confirm that the oil pressure sending unit wire is gray? The PO installed a mechanical gauge in the dash, so I don't have a sending unit on the back of my 360. There is a loose gray wire in that area and from what I can tell, its a gray wire that plugs into the gauge. Of course, I will have no way of knowing for sure until I can get a new sending unit and hook up that wire to see.
