Electrical problem
1998 Other Plymouth Models 4 cyl Front Wheel Drive Automatic 65,000 miles

My 1998 Plymouth Neon/Expresso had an auto start on it built by HORNET COmpany. The unit wnet out. HORENT gave the details as to how to remove there auto start, but couldn't give the details on how to rehook the wiring harness. I am trying to find a guide to do so, but no Chilton;s Guide has this diagram. Any suggestions?
