computer problems....

the problem is i have a rag top 7 and it has holes right behind the door glass. Well after a couple of years the holes have gotten worse and the computer went due to the water getting in it. I sent it to a shop to a guy the works only on mazdas and he odered the computer that was orginaly in the car it came in and wont fit. I think it was a N351. I asked the guy what the computer he took out was and he said N351-9E1. Well the the plug is to big and the prongs are not located where the N351 needs them. I am not sure where I can find another N351-9E1 so please help ... Thanks

What Year is your car?
What engine is in your car (S4 or S5) (Turbo or NA)?

I can give you the correct ECU number after the above is answered

N353 18 880

NOTE - If there's an "R" at the end, it's a remanufactured ECU. They also change the last 3 digits to "881". Example - '89 Turbo Reman. - N370 18 881R. A remanufactured ECU isn't necessarily bad; it DOES mean the ECU was replaced.

There is your info, you need a N353
