I drill holes in my Beautifully Restored Tractor to make way for a set of headlights. Measure 50 times...drill once. #masseyferguson #tractorrestoration
I forget what one was hi and low. The whole system is confusing because the tractor uses positive ground. So my black is actually positive. Best thing I can say is to test your lights to a battery and see what wire gives you high beam.
