Gary Lewis Posted February 15, 2018 Share Posted February 15, 2018 I'd like to create a web page that documents the various computer systems Ford used on these trucks as well as trucks up into the late 90's so people have an understanding of what is available if they want to upgrade. My thinking is to have an overview of what was used, what the differences are, etc. And, that would include pinouts for the various signals, which systems to choose, and so on. And then, as some of us work through specifics for our trucks, to include that info as well. What system we chose, why, how we wired it, how we "programmed" it, and so on. Thoughts? Suggestions? Caveats? Link to comment Share on other sites More sharing options...
85lebaront2 Posted February 15, 2018 Share Posted February 15, 2018 Sounds like a good plan. At one time, somebody was offering an EEC-IV to EEC-V harness adapter to mate the 60 pin female of the EEC-IV harness to the 104 pin male on the EEC-V box. Since the case size didn't change, as long as a suitable firewall gasket (inside on 1987 - 1991, outside from 1992-1996/7) then an EEC-V can be put in place of an EEC-IV. For those with the dreaded EEC-III systems, the under seat location won't be an issue, just adapting the harness and discarding the DS-III and affiliated parts. I am not sure if an EEC-V box could even be set up to work one of those due to the feedback carburetor. Link to comment Share on other sites More sharing options...

I am not sure if an EEC-V box could even be set up to work one of those due to the feedback carburetor. Didn't realize there was an adapter offered. But, that boggles my mind. The EEC-V I'm looking at expects there to be a power distribution center with included relays, like for the fuel pump. But none of the Bullnose trucks had a PDC, so..... Anyway, on this to-be page I'm hoping we can capture why one would want/need to use other resources, like Core Tuning, how to do that, and how to engage them. In other words, to explain the scope of a project and what part various sources play. (That was really a mystery to me for quite a while, and I'm still not sure I understand.)

No, but the 1985.5-1986 models with EFI had the prerequisite relays. The FBC ones had the EEC power relay and the EFI and hot fuel package trucks had the fuel pump relay. 1987 - 1991 models have the relays located just behind the air filter, on the air filter mount. The 1985 - 1991 relays have to be weatherproof, although the 1985 - 1986 power relay is inside near the EEC. Relay boxes that will protect the standard Bosch relays that virtually everyone uses now can be found at most junkyards and most newer vehicles have a nice PDC, some more than one. It becomes a matter of "How much do you want to do?". Link to comment Share on other sites More sharing options...
