Personally, I like the Bosch name.
As I posted in my article on auxiliary battery relays last March 10,
I bought the Bosch 75 amp relay (part # 0 332 002 150) from
Alternative Energy Engineering, orders: 800-777-6609, tech support:
800-800-0624,

75 Amp SPST NO Relay
This enclosed single pole, single throw relay has one set of contacts that
close when power is applied to the coil terminals. It can be used to turn on
12 volt loads of up to 75 amps. Power terminals are 10-32 screws and coil
terminals are 1/4" quick disconnects.
52-330 75A N.O. Relay $17

One of the nice things about this 75 amp Bosch relay is that it has screw
terminals� perfect for #8 or #6 wire. (You just don't find spade connectors
for these larger size wires.)
