I'm having overheating problems. Surprise, surprise. The Roadster has a replacement aluminum radiator and nice SPAL pull fan... however, it doesn't seem to blow the gale that it should, given it's capacity to move air. So, I went under the hood and poked around, only to find a two pin, female connector at the front (top) of the engine. The two wires appear to be Brown with Red trace and Yellow with Light Green trace. Have looked at online wiring diagrams for the "Federal" Roadster (that I presume means - meets federal specifications), but cannot find anything remotely like it. Thoughts?
