I am having some dash wiring issues ! My radio power on/off is affecting my ash reciever light(ash tray light). the ash reciever is always on faintly with key on, but when I turn off the radio the ash reciever brightens.
I would like to add some extra grounds for piece of mind and possibly eliminate one problem.
I have plenty o welding lead to use for this. Where would you all recommend the best place or places to install them?
thank you

 

Battery to body for one.

 

pos side battery to core support
then engine to frame ,engine to body
bed to cab
dash area to firewall

 

Positive side of battery to core support??? Is this correct? The negative is done from the factory.
Clarification please.

 

SORRY NEG side miss typed
