1) I have said many times here that I'm not the guy to ask for advice on electrical issues.
That's why i keep trying to bring people to understand the benefits of 12V and EI.
Install them - or pay someone to if you don't know how - and you'll likely not have to touch your electrics except to replace a battery every 5 years.
2) I generally don't write lengthly treatises here so if you are looking for a step by step approach to anything I'm not your man for that either.
3) Time is on my side. As the EI haters here age it will be harder and harder for for them to deal with those pesky front mounts and they'll convert to something easier and more reliable.
4) I am very patient.
