I saw in a wiring diagram for my 86 Iroc that the ign ports on the fuse box go through the guages fuse. Does anyone know where the bat ports on the other side of the fuse box go through. I don’t want to draw too much power and blow a wire.

 

This schematic is from the 85 shop manual for TPI,..... You can see the 2 BAT cavities on the Fuse Box and trace them back to the Light Switch, then the 'G5' PIN of the C100 connector and back then to the starters fusible link.



This schematic shows everything factory connected to the ACC fuse in the 85,......

 

So it looks like the bat ports do go through the 20 amp acc fuse. I just wanted to make sure that there was a fuse so I wouldn’t burnout a wire going to the battery. Thank you.

 

Glad to help !!
