Can I use modified TBI harness w/ 7730 ecm?
I am converting a 1989 tbi system to tpi. Can I use the modified tbi harness(add injector leads)and use the 7730 ecm, or do I need to use the tpi harness?
ALSO, DOES ANYONE HAVE THE DIAGRAM FOR THE HARNESS CHANGE, ALL I HAVE IS FROM HAYNES MANUAL AND TECH INFO., NO DIAGRAM.
Thanks, Nick

My dad just changed his 92 RS TBI over to TPI. He used the stock TBI harness with a 7730 computer. He's still putting together the directions and everything, so give him time.
