2ZR Turbo Yaris

A little wiring for the trans fan

I decided to go with a relay since I had one gathering dust on my shelf. Here's a drawing of my wiring schematic.



And a little more soldering/heat shrinking for the relay ground. I got this attached but no pic.



Relay mounted. Terminals will also get the soldering and heat shrink. I've got some really big heat shrink, so I'll likely cinch up the split loom that all comes together there.

One thing I've noticed is these cheap relays (not sure if yours is) don't fair well in the open elements (or the engine bay). I've had a few relay failures that were mounted in the engine bay. I'd look into a waterproof one or slather the bottom of the relay (along the seams) in grease to keep moisture out. Food for thought.

Yes! I was looking it over and it doesn't look waterproof. I did wonder about that. I actually thought about coating the bottom in RTV sealant as it's rated for several hundred degrees. I may just pick up a waterproof one as per your suggestion. It would be a simple, couple minute job to remove this one and install a waterproof one.
