This may be a stupid question but here it goes... I have a 200s and the boot is messed up. I want to change the wire but do not understand how it connects to the coil. after unscrewing the cap do i just pull the wire straight out? So the new one cut to length and push it in? This is all new to me. Lastly I found two types of plug wire one snap on one screw on which do you suggest? Thanks
