Answer

Is it one of the big fuses blowing or small ones? Did you check the whole harness runnging down the side of the transmission where the oxygen senor wires come out of the main harness?

it's the big fuse for the eec and yes i have not found any problems with the harness,the fuse blows as soon as i turn on the key at first it would blow i change the fuse it would be fine for a while then it would blow again, now it blows as soon as i turn on the key

Answer

ok, the big fuse supplies power to the sensors on the engine. so don't bother with the wiring to the eec module. you ll have to get a 25 amp circuit breaker and put two wires on it. plug the wires in where the fuse goes. be careful not to damage the fuse socket. once you get that pluged in try un plugging harnesses untill the breaker quits tripping. I'd start with the transmisson harnes that runs down the back of the engine. the connector is located right behind the intake. you ll see the wires running down the top of the trans.
