Does anyone have a wiring diagram for one of these barry grant fuel pump controllers? I have one but unfortunately don't have the instructions. It's part number 180300 and is the fuel pump controller where you can flip a switch to have high and low fuel pump speeds. I've tried searching and also calling holley with no luck. Amy help would be greatly appreciated. Thanks!
