I've got a na s130 that im doing a turbo swap into nothing serious right, but here's the kicker the junkyard I got my engine told me it was an 83 so I bought all 83 parts harness ecu etc only to find out that it was an 81 engine. Now the shop doing the work is having problems getting the ecu and harness to play nice with the engine:(. So my question is will these parts work our do I need to go buy a different harness and ecu I've already got the 81 dizzy. Any help would be appreciated
