Hi All... Electrically challenged person here, so use layman terms if you will please...
Trailer project.....
On my trailer, I have a 12v pump (draws 6-8 amps) which I want to operate from the auxilary power pin in the trailer plug (7 wire) on my truck, OR from a stand alone dedicated battery on the trailer. I want the pump to shut off whenever I hit the brakes. There is another power lead in the 7 wire plug for electric brakes I can use, or if it draws little power, possibly use one of the turn signal leads as they are on the whole time the brakes are applied. My initial plan was to add a 'normal open' 12v solenoid valve.. Was speaking to someone about it and he came up with the idea of using a momentary power off switch for the pump intstead. Hoping it to be a lot simpler and less expensive. Is there an off the shelf product I could use, been digging, but no luck so far.
I 'subscribed' to this thread, so I will probably respond immediately if anyone has a question..
Thanks for the help
