Fusebox internals - map/diagram

[Huw Powell]

On my diagram the ECU power comes from B87F, output from the fuel pump 
relay - which is why that is usually labeled "Jetronic".  A G/Y wire.

But that has to come with a grain of salt, because these fuse boxes had 
the "spare" fuse on the side that was in this circuit, right?  And then 
of course the EFI might be quite different from the CIS variants...
