Bob,
Although you are correct, it is more convenient and way cheaper to 
install old fashioned relays of say 35A. They are readily available 
including their fitting boxes from various cars in the scrap yard or 
ebay for next to nothing or you can get them new at a general car parts 
store for very little. If things go wrong they are far easier to 
diagnose (you can hear them working) and rectify if you have a few spare 
relays in the boot.
