I'm checking and replacing / repairing /adjusting the FI system on my 76 280. At times I could use more hands to hold VOM leads, power leads. etc. Case in point, testing the air flow meter, I need power and ground on two terminals, meter leads on two more and another hand to open the flap. I removed the outside case from a sensor connector and it fits nicely on the two terminals that need 12v power, an aligator clip/wire on one test terminal, holding probe on the other test terminal and one hand free to move flap. The new/used test connector can be used on other devices that have the two prong conector. Hope this helps anyone in the diagnoses mode.
