Hello, I have a 73 240 (with elec fuel pump factory installed) and purchased an MSA alternator adapter plug last year. Just getting around to installing this with a ZX alternator (internally regulated) and I have read multiple posts about the fuel pump relay being energized and draining the battery (just on the 73 with the factory fuel pump relay). After searches, I could not find any specifics of what is needed to correct battery drain. I have read that you need to wire a relay in, but again no specifics. If anyone out there has the details, It would make a great writeup (color codes on wires/pics/etc.) I would sure appreciate any info you guys have. Thanks
