Welding question ?

Probably a stupid question haha . So I've welded on a ton of cars before mostly modern ones . Always remove the ecu before welding . I've welded on my dart and didint remove anything . But now thinking about it ,should the mopar orange box be removed before welding on a old mopar ? Doing some patch panel repair today on a 1978 dodge maxivan and just curious ?

Thanks guys !

Generally on our cars disconnecting the battery should be just fine, but unplugging the ECU would be an extra safety measure.
