Grrrr...it finally went

[Z Ya Later]

Well, after almost 140k and 14 yrs., the Opti on the Z went I believe. I fired her up last week to go home from work and she ran for about 10 sec....and hasn't run since. I followed Rob's testing procedure and got nearly 12 VDC on the 2 inside pins, but barely 0.05 VAC on the outside pin when cranking. So, either the Opti is gone or the harness is bad.

Is the harness for the Opti a seperate piece from the main PCM harness? Or is it all one piece? And how would I test it? Thanks guys.

140K . . . not bad for an opti.

Oh . . .also, I don't know whether the opti harness is one piece or a separate piece.

Does anyone have the answer ? ? ?

Anyone know? Or how to test the current harness?

After poking around on Shoebox's site, I found the other side of the connection, as seen here...



Thanks Rob
