Is this good for the plugin from a trailer to a truck for lights and brake controls?

Yes. I use it on electric and electronic devices.

What is the difference between this product and the crc qd contact cleaner (blue can)?

Blue label is plastic safe & leaves no residue. Green label may attack & fuse plastics, also leaves a oily residue you may not want. This happened to me.

can this be used to clean ceiling fan switch?

I don't see why not. Just make sure you just hit the switch if any delicate wood and/or plastic is around. I haven't used on ceiling fans specifically, but have used on plenty of switches in a multitude of devices. Works like a champ.

Can i use this to clean the pins of the connectors to the ecm in a vehicle?

DREMEL tool brushes with brass, bristles and @ low speeds are your best bet.

Worked well to clean corroded automotive contacts. It also helps to protect some trailer connectors exposed to weather. Easy to use with the thin straw it comes with.

Made a very noticeable difference on contact points that I couldn't get to with a wire brush.

Easy to use spray to protect wiring connectors exposed to the weather. It's much less expensive than another popular brand. I use it for my travel trailer power connector and towing connector. A must have. It's supposed to prevent poor, high resistance connections, which often causes connectors to overheat.
