looking for advise
 

I am new to this form and to Saturns. I have a 2003 Ion auto 2,2 that is being made into a half mile dirt track car and have some questions...
#1 does anybody know of a stand alone wiring harness for the Ion
#2 has anybodyinstalled a steering wheel quick disconnect
#3 I have done some looking and I am having trouble finding a header, cab somebody point me in the right direction
and finally any advise or tips using this vehicle.
Thanks in advance
Scott
