Near Intersection of I-35 & I-90 Southern Mn. | Have done this many times. The Rate controller has ground on pins 1 & 2. This is what you should use for the ground for your On/Off valves. The constant power for the valves should come from Pins 36 or 37. The triggers come from Pins 4 - ? depending on how many on/off valves your have.
Don't use chassis ground for the valves. |
