A couple weeks ago, I posted about how to rewire a pair of Williams GP30s to run together. I made one mistake in that though. At the time I posted it, I had not yet rewired the headlights. For the second engine, I said to take the wires from the rear headlight and run them to the front. This is not correct. All you have to do is switch the yellow and blue wires at the front of the second engine. Don't worry about taking the back ones and rerouting them to the front. There must be some kind of rectifier at the front and rear and headlights, so instead of sending electricity through either pair of wires, it will just send it in the opposite direction through the circuits. Hope this helps out.
