So I've been planning on swapping my L03 to a L98 for quite some time now, but I've been having trouble finding a wiring harness and ecm with a chip. None of the junk yards around here seem to have and third gens and the f body specific junk yark "don't carry tune port cars no more". This isn't all I've looked but I've been trying to find some for cheap, hasn't worked out yet. I might have to buckle down and spend a couple hundred on ebay but first I've heard of truck guys modifying their tbi harness to work tpi fairly easily? Is this possible? I've got a 92. If this did work would my ecm work properly with the 350? Im guessing not just asking tho. Also even if it is possible would it just be better to use a tpi harness anyway? Thanks
