I bought the software and the appropriate adaptors, but I cannot figure out which connection to plug it in to... can anyone point me in the right direction? pictures would be FANTASTIC!!

should be a capped connector by the back of the engine.will be grouped w/ the 3 connector trim switch plug.they have labels on most on the connectors.

On the 525, the plug is on the port side of the intake and is attached to the SS bracket that holds the throttle cable. It will be on the back side of the SS plate. You will have to unplug it from the cap that it's plugged into.

if he posts a pic of the engine,,could put an arrow on it and show him.

It's on the back side of this plate.

thanks for the pic,at my advanced age,I forget were these plugs are.but they are usually easy to spot.

Is that a stage 1 - 3 kit on the 525 ? If so which one and how did you like it?

What version is your Diacom SW? I bought it a back in '2005 when I had a 496HO. It worked great. It still works with my 525efi but I noticed it seems to put some dummy data is some of the fields.

Perfect!!! THANKS EDDIE!!!!

Not sure.. I'm sure it's the latest version.. I just bought it about a month ago.
