how have people installed and wired their slimline fans?

That's an interesting way to do it Bash haha, already got rallye blanks fitted, sounds a lot more complicated that wiring to the original relays.

Cut the wires on the fog light plug solder to the slimline fans sinplest it could get. Already fused and relayed. Takes about 5 mins. Simplest way i thought of doing it keeping oem look

depends what that circuit is rated and fused to in amps.

simplest way would be to run a whole new feed via relay and install a switch on the dash (you can use an oem switch if you like) + add in the temp sensor if you wish to trigger the fans automatically.
