Understood. My rationale for providing the info on the caps used in other Ford PCMs was to demonstrate that the full-size truck computers of this era are somewhat unique in their circuit design, and perhaps that is why they are failing at a much more rapid pace. It would be interesting to know what the truck EEC-V PCMs look like inside.

Back to the selection of the proper replacement caps, do you happen to have the part#'s for the ones you used Guy? Even if I limit my search to Panasonic, I'm finding multiple choices of caps with the same exact specs. The ones I've tentatively selected are from the NHG series as follows...

10UF 63V 105c NHG Series PANASONIC ECA-1JHG100

47UF 25V 105c NHG Series Panasonic ECA-1EHG470

Here's a link to the spec sheet...

An interesting note on this series of caps, which may mean something, or nothing at all.... Panasonic doesn't even offer the 47uF in 10V or 16V; the lowest voltage offered is 25. Perhaps they were problematic in the lower voltage spec parts and thus no longer offered???
