actually Bob, you want the battery and engine both grounded to the cab, where your switches and gauges are - the frame ground is usually taken care of by the various mount points, tho' sometimes it helps w/ the tail lights to have the box grounded to the frame cuz there's usually rubber shims and the bolts go thru the wood - a ground connection on either intake or exhaust doesn't usually last well due to corrosion and heat cycling - put it under one of the starter mount bolts, right where it's needed most - as pointed out above, there's a threaded hole nearby that the factory intended for that purpose [and one behind the top outside of the battery] - both batt/cab and cab/starter only require about 8" straps
