ok so i have a 00 cav that is a rallycar it has been stripped inside so all the electronics i need is the basics.....the car had a 2200 with a auto behind it i swapped in an eco with a five-speed behind it and i have not had any luck finding a harness or a computer for the manual trans i was just wondering if i can use one for a automatic car like i said before i just need it to run the motor thats it would this work out for me or am i way off?? thx for any help
