You put it in on the low side in the line about center of the engine.
dodge didnt put a 5.7 in there dakotas. you either have a 4.7 or a 5.9. is its the 5.9 its on the side of the throttle body.
On my 2-door 99 dodge Dakota truck manual transmission. I put in four quarts in then check the oil stick. I always end up putting half of another quart. So 4 and 1/2 quarts.
ON the left side of the valve cover should see the oil cap
