Installation of the AUX valve(3rd function) is easy.I can install the kit in less than an hour. It stacks onto the 3point valve or #1 AUX valve if you have it. Definitely remove the seat. This gives you great access. Don't forget to unplug the seat switch. I have installed lots of these valves and hoses to the front loader frame for customers. Have the 2 hoses split with couplers so you can remove loader if nessary.Locate these couplers approximately under R foot rest. Fab a L shaped mounting bracket for a second set of FF couplers if you have an SSL type mount for your bucket. The bracket can be mounted on the cover plate that protects the steel lines on the front loader cross member. This set up gives you AUX hyds out front and the ability to use other attachments. Get the detent kit for the valve. I thinks its only about $50. this gives you continuous flow option both front or back. You may be able to modify the valve lever to make it more user friendly with the FEL valve lever.
