Ahhh yeah the wires were a pain in the A$$ but I figured out a method to get the CLICK I wanted to hear when installing them.
It's no secret but the trick was I had to actually hear and feel the wire click in so I used an actual plug and a wire with dielectric grease before installing them and simulated the plug and wire mating... my brain had an actual idea what to expect which help ease any doubts with the connection.
Remove coils and installed plugs:
-First I installed grease inside the wire housing.
-Second I slipped the wire on the plug and slide it down and held it for about 5 second to squeeze out air. When the plug wire stops sliding back out by its self step back for a moment and take a deep breath and a drink of something

The tricky part is next. Okay with one hand you have to align and keep the wire boot straight from bending as you apply pressure in word. The other hand has to pinch the top and bottom end of the boot and push keeping it straight. It took many tries to figure it out but when I heard the "CLICK" I figured out the trick. Most wires went on very easy and quick. Only three wires gave me problems.
