Review on BOWERKAR Water Coolant Temperature Colors by Joshua Days

In theory I was impressed with everything this kit had to offer. The 1/8 NPT gauge is the perfect size and looks cool in the pictures. I had trouble extending the wires to 20 AWG wire and shrinking them to increase strength, they are very weak wires. I think the wire gauge might be 24 AWG. I connect ground to ground, power to ignition, signal to sensor wire. Continuity test to ensure connections are made correctly. Resistance test to ensure there are no short circuits. Turn on the machine. Nothing. I'm a mechanical engineer. I understand what I'm doing. I'm tempted to take this thing apart, but then how do I get it back? Can I actually get it back by stripping and crimping the wires? After this failure I will definitely buy from another vendor, maybe Innovate or AEM.
