I would rather have relays for under-hood loads under the hood. That includes, headlamps (2), horn, AC clutch, ignition, radiator fan, and fuel pump. That is how all newer cars are, indeed I used a box from a 95-99 Jeep in my two A's (see avatar). That keeps small currents on the bulkhead connector (can melt otherwise) and I run small 20 awg ribbon cable from bulkhead to relay box.
