I am looking at ordering the new maddad claritygauge set and I was wondering if spending $19.95 on a wiring kit and $49.95 oil pressure sandwhich adapter is worth it. Wiring kit with kit price $19.95 http://www.daddysscp.com/dcart4/product.php?productid=133&cat=13&page=1 Sandwhich adapter with kit price $49.95 http://www.daddysscp.com/dcart4/product.php?productid=109&cat=13&page=3 I like the idea of the sandwich adapter does anyone know a better source for it? Also I hope the adapter doesn't mess with the quality of the oil filter seal or cause any clearance issues.
