oil sending unit problems

i just replaced my oil sending unit, but i forgot which way the wires go. I have a three prong thingy on the top of the oil sending unit. But when i put the wires on it blows my fuel pump fuse. can anyone tell me which color wire goes on which place

Wiring applications may or may not differ from year to year, and between 4 and 6cyl models, but on my 86 4cyl, it's like this:

Brown(tan?)/white stripe > | _ | <yellow/black stripe
.....................................^Brown(tan?)

Also consider your new sending unit may be shorted out(defective) or the parts store gave you the wrong part.

Let me know if this helps...
