James1549 is dead on, and so is billangiep. Go with the direct fit. It's more money, but better in the long run. It's the only kind that I would use in my repair shop. The universal ones requires splicing and as I posted we are working with a low voltage and a tight range as well. If the connection is not done correctly, the resistance will be too high thus the voltage too low and you can have the same problem again. Plus, you must insulate them, and if an error is made here, another problem can occur. It's just not worth the small savings. If you have it done at a shop, demand direct fit and ask to see the box.
