Default 1990 honda civic cooling fan Problem. Need help asap!

I just had a new engine swapped into my car and its getting hot and the cooling fans are not coming on. I do not have a fuse panel cover so I am not for sure which fuse is which.

Also over by the passenger headlight and airbox area there are 3 plugs but only one of them is connected to a relay.. Does anyone know what these plugs are and if they need relays? Anyone have any pictures of these connections and what they need to be plugged into?

Thanks in advance.

check #15 which is 15 amp, if that doesnt work, the relay could be bad...

Was it working before the engine swap? if so my 1st guess is they didnt plug the fan switch back into the block..

Its a 2 prong switch in the back of the block around the oil pressure switch and oil filter area

I checked the fuse its in good shape.

I am taking a pic of the relay, can someone tell me if this looks right?

Thanks

if you have a/c you should have 3 relay boxes..obviously you have the plugs for 3

That one in the picture and there should be 2 more by the radiator..

but if thats not the problem check that switch on the back of the block

I checked the switch on the back of the block and its connected.

I can't find the relays for the cooling fans anywhere near the radiator...

Do you happen to have any pictures of these? Or a more specific location?

That's fine for now,,but thats how fan motors burn out,not to mention what its doing to the weak stock alternator.
