Power DC fuel pump off trailer plug
Need help here. I know it has been discussed that getting 12V to the hot pin on the 7 pin trailer plug takes some tricks. I tried plug in, start truck, press brake... no luck. fuses appear to be good.
What i am trying to accomplish is power my DC fuel transfer pump off the 7 pin. I have it wired with positive to the 12V pin, and NEG to Ground as it should be. all other spaces are empty. When i plug it into an older GMC we have, it works perfect. on 3 of our new fords... no juice. whats the trick?
