quick check on engine grounds
 

putting a spankin new harness on my car, and it's been over 2 years since she ran so I'm a bit ( alot ) fuzzy. want to make sure I have the grounds correct.

there are 2 on the emissions harness (ontop of motor going to ecu) I see. I know that one goes to the coils bracket. I read the other goes to the UIM, but where exactly? then the 3rd and biggest one is on the harness that runs along the driver's fenderwell. no clue where it goes, but I saw an open hole next to the engine block coolant drain, maybe there?

thanks for any help. not only has it been forever since I pulled the motor, but I eliminated probably 60 percent of stuff that plugs into the harnesses. well, back to the head scratching.

1. Bolts on of the bolts holding the solenoid rack to the block
2. Back side of the UIM where the hoist hook is
3. Driver's side of the engine block (pretty much anywhere clean that will reach)

thanks much!

while we're on it, here are some plugs I'm not familiar with.

pic 1) these plugs are sitting near the solenoid rack

pic 2) this 4 prong female connector sits on the side harness

pic 3) this single prong male connector sits on the side harness also

pic 4) this single prong female connector seems to match the one in pic 3, but it doesn't want to reach way over there. it sits on a branch of connectors that I think connected to all the emissions stuff I removed on the uim/lim.

any help?
