Hey all,

I got a davies, craig thermal switch (tried to make one but too much effort) and the wiring harness that comes with it pre wired looks wrong in my opinion as to what the wiring diagram says. below is a pic of the relay and the link for the install guide. if you could tell me which pin is what on the relay that would be helpful. i think i know which is which but i would just like a 2nd opinion.

The wiring harness that came with it has the [Red with fuse] on the middle pin, [blue] on bottom, [black] on the left and [green] on the right.

Where as i think the [red] is on the bottom [blue] on one of the top two, [black] on the right and [green] on the left.

Yes, you are right. Wire it up as per the instructions (Reference 2). It wouldn't really matter if the red wire is on pin 87 and blue on the bottom unless you were planning to power 2 items then you could use the two 87 terminals (it is a twin throw relay).

The switch closes (and turns on the fan) when the thermal switch activates and powers the relay coil.

Hope this helps.

      Shoota's R33 GT-R RB30/26

      By Shoota_77 · Posted

      Hi guys, long time no post as per usual! It's been a busy year so far, the biggest thing being a new job.  After 28 years in the automotive industry I decided it was time for a change.  I was losing faith in the industry and where it's heading.  Now in a completely different industry (electrical) working for a company that manufacture water pump contollers.  Not as sexy as cars but it's an interesting,  challenging industry. I now don't work Saturdays which is a bonus!  It's still 50-55 hours a week but having Saturdays ack after 28 years of working them is awesome!   No news on the GT-R but i did decide to add some more JDM goodness into my life....           1990 300 ZX.  She's not perfect but for a 35 year old car she ain't bad!  Just going to tidy it up a bit and enjoy it.  It's currently auto but will start stockpiling everything for a manual swap. It WILL distract me even further from the GT-R but im hoping not for too long! It somewhat proves a 6'8" freak can fit in a 300 ZX.  Sort of...  I drove it home from the previous owners house in Melbourne via Black Spur and Merton Gap (2 awesome bits of Victorian twisty road) and it was amazing!  Handles so well!!!   I don't think it would be worthy of a full build page but I'll post up some of the upgrades here if anyone is interested?  Cheers guys!

      Living With An R33 Gtst

      End game is to: - Remove all the slop from old worn parts - Adjust setup so that the wheels actually fit and the car is drivable (currently it is not because of the extreme rubbing on the guards).   Progress over the last couple of days, removed the rear hubs! Next steps: - Buy bushings - Replace bushings/bearings on hub - Reinstall

      A few random issues have popped up since my last update. My WMI pressure sensor failed within about 10 minutes of it seeing liquid. It was a 20$ China special, so I'm not surprised. My name brand replacement should arrive today.  My power steering assist also decided to crap out last weekend. The usual, works for about 60 seconds after starting the car then I lose it. I dusted off my old copy of NDS and connected to the HICAS ECU. Code 4 for assist solenoid.... I tested the solenoid and it's fine.  I knew the day where my HICAS ecu would crap out would come, and I welcome it. It was the last HICAS part on the car that is now in the bin. I've ordered an SSR and I will control the power steering solenoid with my Haltech ecu. It will be nice to have proper speed referenced assist again after all these years.
