As the title says i have a EFI harness but i do not know what year it came off of. This time i have pictures, please help me identify the year and what i will have to splice in order to get it to work in my 84 i have pictures of any connectors you need, i believe it is a 89-90 because it only has 2 relays. one by the MAF and one by the EEC. Thank for looking if any more pics are needed let me know
