Datsun / Nissan 280 ZX ECU 

Up for sale is a Working, in excellent condition 1983 Datsun / Nissan 280 ZX Engine fuel / engine control module. Part number-- A11 652 805 /  A11652805     , This may fit other models/years, my list shows this may fit most 83's with the manual transmission, but that's up to the buyer to Verify.  As always your best bet is to match the part number to the one on your original ECU. These units have been NLA for quite a while now, and are not at all easy to find, at any price much less as fair as this.
