Put it where the sensor is now, or, get some fittings, an "T" off from there, so you can have the sensor in there as well.....

Default check your oil bypass valve

Now the needle seems to work correctly, but at idle, goes to zero and triggers the light again. If I throttle it, it will climb, the more throttle the higher it climbs, but if I stop at a stop sign, it goes back down to the "8psi" point I guess you can call it for idle then slams to zero and triggers the light. Could this be an oil pump issues? Any help would be great.
oil bypass valve is located on the front of the timing cover. usually a hex head. contains valve and spring.

I would install a mechanical oil pressure gauge. Mine does what you described and it was soldering that has come loose/lost continuity on the back of the cluster

did you get this figured out? If not, check the oil bypass valve. allen wrench bolt facing drivers side. on timing cover. take out the plug, spring and valve. clean and check for scoring on the valve. clean out the engine side as well. might be able to buy the replacement parts as well, if so they are cheap. these stick and screw with oil pressure on v10, especially at idle.
