Temp from what i know there should be two of them one for the gauge and one for the computer,

Just looked on alldata and it is the one for the computer. i tried to post the pic but it wont do it may be some one can get it to work and it is number 4 in the pic

i think its the oil pressure, i know on my 91 fullsize the temp is on the intake near the thermostat

so my vote is oil pressure

Not 100% sure but I am mostly positive that the temp can come off of the intake manifold, water neck, or the head.

oil pressure monitering sensor. im guessing on your truck you have a dummy light as opposed to a oil pressure gauge right? on my yota i have the same thing. in fact i broke this sensor and had to replace it.

well, auto zone told me the other day that it was the oil pressure (the guy even went outside and pointed it out to me) and then today I took a picture of it with my camera and took it to ABC and they told me it was the temp. They brought one up on their computer with a photo and it said temp. But it is a chevy 350
