Ok the wiring is kicking my butt.

Hope some of the tech gurus can as assist me.
Fan is installed and wired to a dual relay with 30 amp fuse out of an old Toyota.

Q. On the pressure switch one wire goes to the rely and the other vehicle ground? (pic 1)

Q. Does it matter which wire ( yellow/ green - black white red)from relay goes to pressure switch? (Pic 2)

Pic 2 Black Yellow in center 12V to fuse. Blue wired to 12V + to fan


Thanks.

It looks like you are populating the fusebox under the hood using sumotoys method?From memory I think the pressure sensor pulled to ground when switched, so you connect that to the relay coil on one side, on the other side of the coil jump hot to the fuse you populated in the box. Then run hot to the common on the relay and connect the NO contact to the fan positive. Ground the fan negative somewhere along the line, I found a Toyota connector in a 4 runner that fit the JDM fan. I will try to find the thread. HTH
