cross reference vin # with correct ECM

[wivrrat]

Does anyone know where I can cross reference my vin # from my 83 nissan 720, z24 pickup to the correct ECM # for my truck. The ecm in my truck now is A16-601-032 but searching for a replacement, I came up with A16-604-035 from rock auto and ebay. Thx

Not sure where you could check that, maybe call a dealer. The one I have from my dads old 84 KC Mt rwd has the number A16-603-034 on it, I'm guessing they vary by trim level but for all I know it could be a serial number.

Found the info I needed. The ECM part number A16-601-032 is for a vehicle made between 1/83 and 4/83. The number A16-604-035 is for vehicles made between 4/83 - 4/84. Two different parts for one year. Wonder if they are interchangeable? Thanks for your input. Mine must have been built the first part of the year as its a 032 part #.
