If anyone is  doing  a  I-4 conversion and  you do  not  understand the
wiring harness,I will make my suggestion to you.Send  your  harness to David
Marshall .He  did  an outstanding job  to  my  harness cleaned it,wired up
for the  other things and  soforth and  so  on .I have not tried it  yet
but for the  work that was done on  it  I would have  paid  more for it .
Thanks David If  you read this.
