Telkwa Posted March 25, 2013 Report Share Posted March 25, 2013 Ours is A16-615 046. I found a couple of ECU's on 720's at the junk yard numbered A16-615 043. One of those was on a truck just 3 months younger than ours. Does anyone know what's the difference between an 043 and an 046? I'd like to have a spare ECU. Quote Link to comment
datzenmike Posted March 25, 2013 Report Share Posted March 25, 2013 It will likely work (I'll look the number up when I get home) but it could be manual/standard, altitude modle, California emissions model, 4wd/2wd, long wheelbase/short, HD or camper option, air condition, changes in emission sensor or contriolls.... lots of stuff even a change in emission rules month to month can alter the ECU mumber.

Telkwa Posted March 30, 2013 Author Report Share Posted March 30, 2013 Hi, mike - Apparently the forum was broke for a couple of days? I imagine you've been busy. If it would help out at all, I'll look up the ECU number. Is there a link or something? I found the Jim Wolf webpages, but they don't list the 720. Looks like the truck entries start with the D21. It appears the "043" is fairly common. Found several on eBay. Haven't found any "046" yet. Quote Link to comment
datzenmike Posted March 30, 2013 Report Share Posted March 30, 2013 A16-615 043 isn't really a Nissan part number although it does ID the box. See if you can find another number on it somewhere on the outside. These were all used after '84. California... 22604-62W01 22604-62W6 Federal.... 22604-80W01 22604-80W11 22604-81W01 22604-82W01 22604-84W01 Quote Link to comment
Telkwa Posted March 30, 2013 Author Report Share Posted March 30, 2013 The shiny sticker that says A16-615 046 wraps around to the top of the box. On that upper part of the sticker there's a big "4". There are no other identifying characters of any kind on the outside. On the circuit board inside there's a board I.D. : A17-001 032-3 I don't imagine that helps any... The circuit board looks nice and clean, considering it's out of such a flea-bitten old truck! Quote Link to comment
Telkwa Posted March 31, 2013 Author Report Share Posted March 31, 2013 I picked up an 043 at the wrecking yard today. Total experiment. As soon as the truck is functional again I'll swap ECU's and see if there's any apparent difference between the two. The wrecking yard ECU came out of a 2WD KC manual trans 720, build month /4 of '85. Ours is a 2WD Cab/Chassis, manual trans, build month /7 of '85. Quote Link to comment
