Hello and welcome to JustAnswer!
The ground on the right side of the engine near the alternator goes to a bolt just above the alternator area. There is a brace that runs from the intake to the accessory bracket on the front of the engine, this ground cable goes under the bolt at the accessory bracket end of the brace.
The ground point on the left side of the engine is at a bolt on the power steering pump bracket. One of the top bolts of the pump bracket has a short stud on it where the ground cable will go, and then a nut installed on the end of the stud.
What about the starting harness wires to the fuse/relay box between battery & coolant reservior. Where does the additional red line off the positive cable attachment go & where does the green wire labeled "fuse link 10 gauge" attach. There is a compartment on the left side of the relay box that comes undone, but there is only one bolt coming up & it has an external star attached to the nut that goes on the bolt.
And there are 2 lines on the right side, not just one. l take it that they both attach to the bracket at the end of the brace.
When I went to the Jeep, there is not a stud or nut on the power steering pump bracket. I see what you are describing (page 10-19 Figure 17.3b of the Haynes manual). However, the pump I have looks more like the pump to the 4.7L V8 in Figure 17.3c on that same page. The bracket the pump mounts to is an aluminum "<" bracket that is mounted to the left cylinder head & there are only 3 bolt holes. Can I install the ground under one of the bolts between the pump & the bracket, or will that cause a problem. Other options is the threaded hole in the front left engine block below the valve cover, or can it be grounded to the stud on the valve cover between the 1 & 3 fuel injectors?
You can bolt the grounds down under any bolt head, the locations I sent were just the correct ones. Bolt them down anyhwere you can find and everything will be fine.
You should have one positive cable that goes down to the starter, and the other one will go to the back of the alternator. Either of these will have a piece of fusible link wire in them. Maybe the other one you are seeing is the one for the alternator?
