Default 350 TBI: oil pressure switch needed or no?

Long story short I'm installing a 350 TBI into my 89 YJ. There is a port that comes out of the driver's side rear of the block that has this http://www.autozone.com/autozone/par...4053_9275_5673 sticking out of it. It kind of hits the firewall slightly with the engine in and I "believe" I already have another oil pressure sensor that sticks out from my distributor area. Do I need both? I am running fuel injection and don't want to cause any computer problems if I can help it. I would like to eliminate this one in question to free up some room if possible.

Send a message via Yahoo to OL RED

the one down low is usually for your gauge. the one next to the distributor is for your computer

You can plug them all. the one under the distributor is used most commonly because it near the harness. there's one above the oil filter outlet on the left side you can use. its the easiest to get access to in most cases.
the switch in your link is for the old style single wire gauge. its not anything more. the newer ones have the 3 wire center for the TBI and fuel shut off. if you plan on running a manual gauge then just add enough brass from the top one to get the line out where you can reach it.
