[graham kirkbride]

hi all
i need help...
how do i wire twin rad fans up to a manual switch to make them come on when i want, but also come on when the rad fan switch tells them to ie when the waters getting to hot, can anyone help me

the most easyest way would be to wire the fan's up to the usual wire then run a wire from a switch you have fitted some were in the car to the temp switch on the end of the rad.
Leave the original wires on there but run a wire from each terminal on the temp switch to the switch inside the car.
Thus when the ignition is on you can turn the fans on whenever you want like i have.

follow wires back off fan, connect up postive (live) to the fan then connect neg to earth point. i.e buy a ring connector and screw to the body to complete the connection.

Mine had a pos and neg going too the fan then taken off that two wires went to the thermo switch

I did it to mine and the fan comes on with the ignition and keeps it nice and cool :cool: .

I would recommend simply piggy backing 2 wires onto the thermoswitch & running them to an on-off switch on the dash. that way the original safety system works as well.
What engine are you running?
why not fit a diesel stat to keep things a bit cooler?

the original safety system still works, even thow im using a relay, because im still using the original wire from the fuse box to the fans/ relay,:thumb: ive fused the wire running to the manual switch so every thing is fused and safe;)
