OK I got a b16a sir II obd1 motor i need to swap in My 92 LS teg but its not vtec so I know I cannot used my harness or the harness that comes with the engine due to the fact its jdm and all backwards. So how can I fix this problem, from what I am reading I need to buy a USDM GSR or civi SI harness. Is that all i need to do?
