Failsafe mode fuse #32 it blows up?

My vehicle listed above is in an eternal limp mode. The overdrive signal estar flashing so I did a little research and found out that the fuse 32 it blows up as soon as I turn the key into the on position. Blew a bunch of them trying to find the problem until I found out that if I take the PCM relay out the fuse not blown. So, I did another research and somebody said to disconnect all the plugs from the PCM and I did so this is the problem, with the plugs disconnected and the relay out the fuse doesn't blow but with the relay in the fuse blows so this guy says in his post that if that happens is because there is a short somewhere between the PCM relay and the PCM connector. Now I have a couple of questions driving me nuts. Which one is the connector in the PCM and which one is the connector in the fuse box? Anything that can show me what wire might be. Thank you a lot

The vehicle listed above is a King Ranch.
