2001 xj 4.0 engine ground locations

I'm just trying to verify where the engine grounds are on a 2001 after an engine swap. I have two set of ground wires on the passenger side of the block bolted to the block under the head. Are there others I may be missing?
 
G100 Battery to fender.
G101 2 bolts on the block near the motor mount and alternator. Battery to block, and PCM+TCM.
G102 1 bolt on the block near the Cam Sensor Assembly, for the capacitor.
G106 Near the PCM.
A braided cable from the valve cover to the firewall. Not really a ground, it is for suppression of static interference on the AM/FM radio.
Maybe a ground on the dipstick tube.

Thanks Tim. These are the 5 locations I've got -

oil dipstick tube stud - multiple grounds
stud near cam sensor - 2 ground wires
bolt holding cam synchronizer - 1 ground direct from battery
fender near pcm - multiple ground connections
rear firewall - ribbon cable (currently connected to valve cover stud, soon to be moved)

That one should go directly to a hard boss on the block, where it is would work but it's not the best idea!
