Just avoid the similar "double bullet" connectors found on appliances as the male pins don't protrude enough to make assured contact (I know, wags will joke). I bought two e-distributor pickups the same time and found one didn't make a reliable connection. Apparently the factory had used an appliance connector. The other one had the proper SAE connector. Wonder if they bought a large lot of the wrong ones, which made a confusing problem for those who installed them.
