difference between years
 

ok, so i have a 91 na. i am looking for a factory service manual and factory wiring diagram manual. i have an oportunity to buy both but they are for a 90. i know that they are both s5s so they should be the same but i plan to rewire the harness for a turbo swap so i want to make sure that i can use this 90 manual to do the rewire on my 91. thanks for any advice.

Im pretty sure its the same.

it is the same.

thats kinda what i thought, i mean dont they use the same ecu numbers. both na use one, and both turbo use another?

I would just be assuming, because if mazda were smart at all, which they are, they would make a manual to cover every model in that year.

yeh the ecu's are different.

the ecus are different?

yeh the n/a and turbo have different ecus

o yeah, but the 90 nd 91 nas had the same ecu. ok i was just confused. awesome so i dont have to search any londer for the right year
