I had the 4 pin rad fan loom but the twin fans i have put on are 3 pin so we cut the connector off and wired it up as 3pin. Now the fans aint kicking in nor is the aux water pump. Either as the car is only started and not driven on the road or there is a problem. Now i want to know if the plug has been wired in right

also there is 2 red/green wires. We used the thin red/green wire not the thick one.
could someone confirm if its connected up right
