hi guys i have an xh ute 5 speed non abs just wondered how hard cruise is to fit and just wonderd when my car runs no fuel at around 2000 rpm it surges and jumps but if u push revs up it goes away doesnt do it on gas

I fitted cruise to mine, although the loom was already there. You'll need a cable to suit the log manifold, or you can modify an EF/EL setup to suit also. I did the latter as I intended to fit a broadband manifold (which is happening now).
If you read the EF/EL cruise doco, you'll find it pretty much as what needs to be done on an XH.
