where is the fuse panel and the diagnostic port on a 90 z n/a???

 

the interior fuse box is under the dead petal
is that the one your looking for?

 

Ya Im Looking For The Interior Fuse Panel, Can You Be More Specific>? Dead Pedal? And Also How Do I Get Me Car To Flash Ecu Codes?

 

A factory service manual will answer both questions. And many more....

 

the fuse box is under the footrest on the left side of the driver side. there should be some screws in the very back left, on the plastic cover, and some on the plastic railing on the bottom of the door sill to take out.
as far as the ecu, i dont know that much about it but rizzspeeds got a link that might help you.
