Thank you. I took a closer look after you posted this and I'll post pics of the tail housings. Now the decision of keeping the one I have and shortening the rear shaft or using the new to me one and buying a shaft. That might mean changing the rear yoke also. Time for more research.

I bought a 4l80e to swap into my 1097a1. The new trans came with a 242 transfer case ( 2520-01-409-2512 / 12447125 ). My 1097a1 has a 242 transfer case in it (2520‐01-452-7569 / 12342643) both are 272 ratio. Can anyone enlighten me on the differences? I haven't actually started the swap yet...

Yep. It's a welded contract on the relay inside the EESS. Thank you.

So, final result. The relay by itself closes to the wires. (See pic) is welded ( see other pics ) this unit is junk!

Yes. See first post with a pic for part number.

Update - I can measure 0 ohms from pin E (would be wire 81a) to pin I (would be wire 74a) on the engine side of the EESS box. That would supply incoming battery voltage directly to the starter. A direct short. Now to see if I can find the short inside the box. If anyone has any experience...

The print I have shows pin B is the run side of the switch. Pin A is the start. Maybe I have the wrong print? Pin I is the trigger wire going to the starter. That's the one getting voltage and engaging the starter that part of my print must be correct. If it were a stuck solenoid it would...

I have tried it with the inside plug off and the outside plug connected and it still does it. I've got the box open right now in front of me trying to ohm it out. No water or viable signs of anything. Looks brand new inside.

The first time I hooked it up. I've never gotten to turn the lever to start it. I've been under and can visually see the bendix gear is pulled away from the flex plate.

It must do more than just pass through it. With the start switch totally disconnected it still sends voltage to wire 74a to the starter. If I disconnect the cannon plug from the engine side of the EESS, There is no power going anywhere as it's supplied on pin e wire 81a. Also on that same plug...

No. Running the original switch.

I've finally got the motor in and am ready to apply power. With the starter switch off (and through process of elimination disconnected) as soon as I connect the negative wire to the battery the starter kicks in and cranks the motor. I'm suspecting a bad smart start box but would like to dig in...
