Hello I installed the gauge and flow meter. It comes on but not working right. Do I have to use two 120 terminators, one at each end? The kit came with two terminators but nowhere to install the second terminator. Needs another T. I am going to buy the parts but thought I might check here first. You would think the kit would come with all parts needed. Yesterday it showed I used .6 gallons and I probably used 12 gallons. Also from the gauge to buzzer & light switch the directions show white, green, red and black wires. Well, my gauge has yellow, blue, white and black wires. My guess blue=red but not sure. Everything else is hooked up according to directions, I double checked. Also when buying accessories to add to this unit it looks like you have to buy another T to install it. They should throw it in and adjust price accordingly. Edited to say I played with it and it is now working. Only question is there is no red wire for buzzer is the blue wire the hot wire?
