After suffering another cooling fan failure 2018 due to a bad relay (see my previous post) I decided to buy some new relays, genuine Bosch relays. And, they’re purple!
I also decided I’d had enough of the sloppy-looking fused jumpers in place of the fan fail relay. They’ve previously come loose, and left me without fans. I purchased the Fused Fan Fail relay from DM-eng, which restores the fan fail light functionality, adds fuses, and removes the need for the circuit breaker in the fan circuit. The fan circuit breaker has given me problems before. The aesthetic value is also great!
I also purchased the ground bus from DM-eng, which sends a separate ground wire to the relays. The stock wiring has the relays daisy-chained with questionable wire connections.
