David Anderson Posted February 13, 2012 Posted February 13, 2012 On my recently purchased '99 LS I removed the engine cover so I could check the condition of the plugs, etc. On top of the engine there was a small plastic box that said DIAGNOSTICS. This same setup was on my '90 LS but I was surprised to see it on my '99. There didn't appear to be any connections inside the small grid in the box so I'm wondering if this is just a leftover thingy or what?
