I've been looking around and stumbled across a statement on eBay which says that the RZ-0159 is better than and can replace the RZ-0139 (Which is currently in my ride).
Is this true?
Also, if this is the case, can a RZ-0088 be used in place of a RZ-0139?
In your opinion (cause I trust my fellow Luders more than everyone else!

) Which main relay should I get to replace my bad one.
Thanks.
