My new question is this. I've seen complete Crossfire PCU/Skreem/ingintion/key/doorlock packages on Ebay.
All taken off a donor car in the 300-500 dollar range. I'm still learning here but my logic brings me to the idea that if all that was working on the donor and I bolted it in, It might just work.
Obviously it would need to be an automatic one like the car I have...
