Part 3 - Relocating the Solenoid Box

Some of the Warn winches like the 9.5ti and XD9000i have solenoids that are sealed in the casing of the winch. Thats great because it keeps the solenoids protected from the elements. Other winches have a separate solenoid pack that is usually mounted on top of the winch but doesn't have to be. It could be mounted to the grill, to your bumper, or anywhere you like. This gives you more options on where to mount your winch especially if space is limited. The disadvantage to the separate solenoid pack is that it is not sealed from the elements. I decided to relocate mine to under the hood. This not only will give me a cleaner install for the winch, but will also help keep the solenoids clean and dry. The challenge is where under the hood can it be mounted?

The solenoid box is roughly 7.5" x 6.0" x 3.5". I've seen some guys mount it on the driver side of the engine compartment behind the stock airbox on the fender, or anywhere around there if they have a cone filter. But since I am using the stock airbox for my snorkel, I was having trouble finding a place to mount it. I came up with an idea that seemed difficult at first, but in the end was very easy and turned out to be a great spot for the box. My idea was to move the PDC (Power Distribution Center) closer to the passenger side fender, move the coolant overflow bottle toward the center of the engine compartment, and sandwich the solenoid box between the two. It worked out kind of like that...

This photo shows the stock location of the PDC and coolant bottle. My white line shows about where the solenoid box will be. The red line is an outline of the bracket that holds one side of the coolant bottle. That bracket will support the solenoid box.


The PDC can be unclipped from its bracket and moved out of the way without disconnecting any wires. Once it is moved, you can see the PDC bracket is pop rivetted to another bracket that is bolted to the inner fender.


Here is a view of the bracket from the front of the engine compartment.


I drilled out the rivets and moved the bracket over about 3/4". I secured it with rivets but not all existing holes would work so I drilled a couple new holes.


The PDC was hooked onto its bracket and the solenoid box was installed. I couldn't just move the coolant bottle over as I originally thought, but I found that it could be rotated 90 degrees from its stock position which would provide enough room for the solenoid box. I had to fabricate a simple bracket to secure the bottle in this new position.


Mounting the solenoid box this far away from the winch requires longer winch cables. The winch cables are 2AWG and I needed 6' cables. The power and ground leads supplied with the winch happen to be 6' in length so I figured a heavier gauge cable wasn't needed. I used the power lead as one of the solenoid cables, and had two new cables made at a local AC Delco store. Since the solenoid box is now very close to the battery, this is good because I can use one of the short solenoid cables as the power lead.

Here is a view of the solenoid box from the driver side. One thing I should also note is mounting it here still gives me room to reach in and change the oil filter, and as you can see I can still access the shock mount. But if the box is ever in the way, it can also be moved from that spot easily.


I thought I would also have enough room to hook up my winch controller, but I ran into a little snag here. One of the AC lines was just in the way to prevent me from hooking up the controller.


I trimmed a little bit of the controller with a utility knife.


And that gave me just enough room to attach the controller.
