I need a FSM or ECU pinout for a 1993 d21. Same as 89-90 240???

Looking at the site linked below:

I found the quote below. Anyways, I am getting ready to do the wiring for my swapover. However, I cannot find the FSM for a 93 (or even my 92) d21. I cannot find a ECU pinout for those years. I can only find the FSM for the 96 and 97 hardbodies on this site, and I don't have a clue if they are EXACTLY the same for my 92 and 93. However, I found the quote below on the page linked above. Is this true: the 93 and lower d21's exactly the same as the 89-90 240sx ecu pinouts??

The difference is the layout and components of the ecu pcb. On that D21 hitachi ecu i posted a picture of, the eprom has be desoldered and removed (yes it should be there for operation, i was just comparing). The 89-90 sohc 240sx ecus are the same, the 90+ D21 ecus are the same (afaik, ive only checked up to '93). The 91+ 240sx ecus are completely different, they use a 16bit setup vs. 8bit of the sohc. Thats why when you see a chipped ka24de or sr20det ecu, they have a daughter board with 2 eproms. They use 2 8bits, more cost effective.

I dont know why you are getting memory set errors, i havent had any problems in that dept. And yes, in rom editor there is not enough room for all the menu buttons so you need to shuffle through to find what you need (it also does not show which one you are on). I know some have fixed this to show all of the menu, but im not sure how. I did not make either of these programs btw, there is plenty of support for rom editor, search around.

Try Live Edit, the latest version is nice and easy to use. You need to load a config file for the ecu, and then the rom image (.bin). I sent TecKniX all the files to host up on his site, probably be up shortly. In the mean time, in Live Edit, you can use the sr20det config file and the Sohc 240sx rom image.

I think the earliest .pdf FSM is 1994. I wonder if there was much or any difference between the two? You might be able to find out if the parts interchange in Hollander with a search at http://www.car-part.com to get an idea.

The D21 Truck FSM is combined with the Pathy for those years that they shared a platform.

Thanks so much for telling me about the 1994 D21 and Pathy's sharing the FSM.

Can anyone confirm whether the 1993 and under D21 ECU's having the same ECU pinout as the 89-90 240sx?? Or if the wire colors are the same (but I doubt it)??

Ok...as far as I can tell, the 94 pathfinder FSM seems like it is going to be the exact match for my 1993 auto FSM.

However, is there a more simplified "pinout" for the ECU?? ya know, like the pinouts you can find for the RB and SR motors and the 240's ecu pinouts??

(If you can't tell, I am worried that I am going to screw up and hook up some wire(s) backwards and fry something....too many wires say IGN, etc)
