Thanks very much Falcon69, I honestly thought that I also searched using a "6" but it's possible that had the "B" wrong in that search, I was uncertain if it that was a B or an 8 Appreciate you clearing the ID up for me now I can move forward with this!
Wagon, I wondered if inexact matches might work too figuring all I needed was to achieve the 12v pass though at a high enough amperage. I was even considering going low tech on this and just fusing in a manual 12v toggle switch to operate the failed solenoid valve which is only a hydraulic system dump valve.
