Jeffrey,

I have moved your post into The Electrical Bay as that is the best Tech Forum for your question.

AM sure that one or more of our folks will chime in here soon with some helpful info and pointers.

I did find an old conversation on the topic which seems to have the info you are seeking.

Unfortunately all those old picture links are no longer functioning, but the description should be helpful.

Let us know how it turns out. thumbs_up

Dan
