99 Xj ballast resisitor ?

Where can I find the Ballast Resistor on my 99xj?

Also does this part go by another name? I had problems searching for it online.

What's it do/for? I have a '99 and I've never heard of it (not that that necessarily means a whole lot).

As far as I'm aware, there is no ballast resistor in a 99. The ballast resistor was present in some models to reduce voltage to the fuel pump. In my XJ experience, The 87 did not have it, the 89 and 93 did, the 95 does not, and the 99 does not.
