Specific Ground Locations

[eresener]

Well I have found the locations for
1 obviously the battery
2 on the long behind the drivers headlight
3 on the apron between the tail lights
4 behind the fuse panel

where else are they specificaly located?

all running lights, instrument lights, for lights, side markers, rear compartment light...still not working...and this is causing me to loose what grey hair I have left (which at my age is not much)

PS I forgot the firewall to the engine block
