Battery ground location ? (pc-680)
 

I'm installing my Odyssey battery per the FWF plans on the right side of the firewall. My FWF instructions say to drill the 3/16" holes for the 2 oil pressure line clamps and the oil-breather tube/alt. engine ground, and to drill the 1/4" hole for the battery ground per DWG OP-27. I found the first three hole locations, but can not find the location for the battery ground on that or the other dwgs. Any help? Thanks.

I remember having trouble finding it as well. I think it's marked as "alternate ground" or something like that on one of the drawings. I ended up just putting a ground block near the top of the firewall and connecting the battery directly to that.
