I know, not another positive ground question! I have searched with no answer found. I hope somebody can help here. 47 GMC with positive ground and I want to put electric wipers in. I bought the 6 volt kit and it looks decent. I want to put it in and try it except the red lead from the unit has a fuse, the black lead has a ring terminal for ground. I do not want to do any damage to the unit by hooking it up backwards and voiding any warranty. Do I just hook the fused lead to the power(negative) and the black lead to the ground(positive)? Or go with red fused lead to positive and black ring terminal lead to negative? Thanks
