frame to ground under battery box...

[Hugo]

I'm installing a battery tender pig-tail inside of the battery box, and the instructions require that the negative lead be attached to the frame.

Where should I attach this? The entire front frame is aluminum (non-condictive).

Is there possibly somewhere on or behind the ECU?

Thanks,

Hugo

aluminum is a conductor you can attach the wire to it. . you can attach it directly to the negative battery terminal too.thats how i did mine.
