Cooling fan

[Hobo Ash]

Looking again then i think the previous owner tried to make it single speed twin fan. Checking wire colours with the haynes, i think theyve left the low speed relay in but instead of the wire going into the left fan, it goes back into the loom. I think both fans have just been wired up with a live and earth (red and yellow/green) without it going back to the relay. Il have to try and trace back the wiring when i have more time. Was thinking of getting rid of the thermal switch and have a manual switch in the dash, i can get rid of the relay system all together then cant i?
