We ran the red/black wires down the loader arms and connected them straight to the machines battery. I bought a 7 pin adapter thinking I could just wire the solenoid red/black wires into the adapter and plug it into the machine. However, I can't find a schematic and ever since I read that comment about potentially frying something on the machine I'm a little gun shy.  The comment did mention lifting the cab and using an accessory connector near the left side pumps <img class="smilie smilie--emoji" loading="lazy" alt="🤷🏻‍♂️" title="Man shrugging: light skin tone    :man_shrugging_tone1:" src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f937-1f3fb-2642.png" data-shortname=":man_shrugging_tone1:" /> So can I just wire into the harness adapter I bought or should I look for a power source under the cab? Any help would be appreciated.</blockquote>
