New owner, few problems

[Vboy13]

Hi, I'm a semi new owner of a 2004 N2O Saleen Focus num 24. I bought this about a year ago in new jersey with about 55k on it, salvage title, from an getting t-boned on the drivers side. Everything Saleen on the car is original, from the entire body kit to the exhaust. And the drivers side door was replace and it was completely reprinted from yellow to now black.

I bought it knowing it was going to need a lil work, I already had to replace the stock rims and tires bc they were pretty messed up with some after market ones.

What is still wrong with the car is this
The lowest speed of the windshield wipers does not work
The reverse lights do not work
The cruise control does not work

I have already checked all the fuses and replaced the bulbs and that was not it wondering if it was some kind of wiring problem?

Also I bought it without the nos bottle, still has all the hook ups and brackets but I was wondering what else I needed besides just a bottle bc there are 4 electrical wires that looks like they connect into something that went on top of the bottle, and I would like to get a new one of those also.

Thanks
Devin
