The Relay dose not have to actually be mad by Bosch. Relays and Temp Sensors are sold on ebay and Amazon. If you want the electrical connector they also have that.

The relays come in different amperages.

The little cube relays are also found on my 92 Chevy Astro Van were there is a row of 3 of them.

The pic of the relay is one I added to my Fan on my 86 Chevy Cavalier.

Hard to see but I did not use a connector (I have since bought some connectors) I used shrink wrap to insulate the female spade terminal s

Unfortunately when I did the job originally I had not insulated the connectors and the Relay bounced around and shorted and burned the fuse in and the Engine had no other fan then the Electric Fan.
That resulted in the engine overheating which split the plastic tank in the radiator and caused a head gasket leak.
A lot of expense and work because I did not do my job properly.
