looking for information on how the forward reverser lever and the 4speed turn control are wired up. A screen shot or a pdf would be a huge help.
First off machine is a 530 to add a little info here on the machine it has a Tag with sn# and says Komatsu but on the hood and boom is labeled Dresser? I believe these company's merged in the 90s. so I have called the local Komatsu dealer who did not have information on this era of machine
