ECU capacitors question

I'm going to replace the capacitors in the ECU's in all three of my OBS trucks over the winter ('92 F150 w/351, '92 F250 w/460, and '95 F150 w/351), and based on everything I've read, and videos I've watched, it seems to me that the ECU's need the same caps, regardless of the year and/or engine/trans combo. (Heck, I think the Fox Body Mustang ECU's use the same ones as well.)

I haven't removed any of the ECU's yet, nor have I ordered anything, but I guess my question is: Does anyone know if they are indeed the same? Has anyone done "multiple" re-caps before?

And, yes. I know they're cheap enough, but I'd rather not pay for additional shipping on a separate cap (or three), as more than likely that would be a LOT more expensive than the actual caps themselves.

Appreciate any experience-based feedback, and thanks!

Jim

Yes, all EEC-IV are same, I believe as well.

I ordered mine from DigiKey. 20 of one kind, 10 of the other, enough for 10 EECs.

There are 2 caps of the same and 1 cap different in each EEC. You need to replace 3 capacitors in each.

Thank you for the confirmation!

And for ordering from DigiKey, a good MN company who also happens to employ my nephew!
