I hope pvanweelden doesn't mind but it's in keeping with his great thread here that I also did a starter solenoid mod to my winch. I'd like to add to his thread how I did that.
I bought the ARB Compressor JK Mounting Bracket used off a guy who had 2 for some reason - paid $30 but they go for $44 at Northridge:
This was to become the platform for the Starter solenoid I was adding - seemed like a good location and was very sturdy once installed.
I used a small piece of angle metal I found in the garage to be the attachment point for the starter type solenoid.
I got the starter type solenoid ready and found two bolts that would work well in attaching the solenoid to the small angle metal I had attached to the ARB Compressor Mounting bracket. I purchased the solenoid at a local Auto parts store and they seemed to know immediately what I wanted, they said this particular one is used all the time for the low-rider hydraulics, so they had plenty of them.

Bought starter cable and soldered the right ends I needed with shrink tubing - it's in the lower right of this picture:
This is where I had my winch line running to and knew things were going to get cramped there with the new Bussman relay/fuse box from pvanweelen's great thread. Rerouting the line took a little time in getting it over to the other side of the engine bay:
I next ran the starter size wire from the alternator to the solenoid mounted earlier:

Finally I attached the winch line to the solenoid with the 300amp fuse I had earlier.
Running the 14 gauge wire from the Bussman relay/fuse box to there was a breeze and now my Winch switch on the cabin Daystar panel operates the large solenoid providing ample power to my winch and ample fusing.
I probably will go with a circuit breaker later for the winch line but for now this has worked well.
BTW - the best Rootbeer out there:
Cheers!
