1994 to 97 were not all EEC-IV because the california cool cats existed lol
But its easy to say most were definitely eec-iv

I looked up the service data, and there is only reference to CCD for 1997 HD trucks, If they used the grey one we would have found references to two systems in the diag and pinouts etc

True. I forgot about the oddball California HD trucks.

 

It dont need CCD, they had coil packs, and didnt want to confuse him even more

He doesn't, I quoted you, your dad had 5.4L and I said they had coil packs.
rock auto, shows Standard Motors, has 2 ICM's, one is grey, one is black, both are supposedly CCD...so...... some cant afford top tier, right then and have to go cheap, cant wait for it to be mailed.

 

I was just sharing, you mentioned the light duty. Im sorry

 

Holy Crap, you guys are making my head hurt.

94-97 were transitional years.
To the best of my knowledge all the F150's, regardless of engine, starting in '94, through the end of the OBS Run in 1996, Required the CCD TFI module, which is typically Black.

The Vast Majorities of 94 and 95 F150's were still OBD-I, outside of California. In 1996 Federal Law required all Motor Vehicles sold in the US under 8500 GVW to be OBD-II Compliant, so *all* 1996 F-150's, regardless of CA or Federal emissions are OBD-II, for Trucks intended for the American Market.

In 1997, the OBS F150 was replaced by the 10th-Gen Body style, which all used the modular motors, and didn't have distributors, let alone require TFI modules, and aren't germane to the discussion.
In 1997-? the F-250, (Call it a Light Duty if you wish, I've also seen them Badged as "F150-7700") Used the same tenth-gen body as the 1997 F150, and the same Modular Engines, which are also fully OBD-II Compliant, and do NOT use a TFI module of any color or type. But they're *really* easy to spot, because for some reason I *still* have yet to fathom, they used this ******* 7-lug Wheel, They're blindingly obvious when you see them.

1994-1996 F-250's and F-350's All remained OBD-I and used the CCD-Type Black Module. As long as they were over 8500 GVW. This remains true for the 1997 Model Year F350s as well.
1997 (Possibly some 1996 MY Trucks) Were sold as F250HD, And retained OBD-I Electronics, the 9th Gen "Aerobrick" Body, and the same combination of 4.9, 5.8, and 7.5l gasoline engines as the 1996.

With the one exception of Trucks intended for sale in the State of California. I don't know this for a fact, but I think this applies to *all* 1996 and 1997 F250HD/F350 built for the California Market, moving to a Mass-Air style Fuel injection and OBD-II Compliant computer. (With the possible exception of Cab and Chassis F-350s, I don't know that for a fact)

Yes, it's clear as fecking mud. So no, if OP were asking about a 1997 F150, or F-250LD they would indeed be in the wrong forum. If They were asking about a 1997 F250HD/F350, This *is* the correct forum for such.

 

few small errors but overall very true. we did cover that and by the end doesnt seem to have been disputed, but makes a good "collect it all"

 

It's Ford Motor Company during a very tumultuous regulatory period.

I'm not going to say there were *no* OBD-II F250HD/350's built for sale to the 49-state market prior to 1996, nor am I going to make the claim that there is *zero* chance of an OBD-I F-150 being sold into California during this time period. Making claims like that is just going to get that one guy to wake up and crawl out from under his rock, just so he can say "Hah, I have the ONE F150 that proves you wrong, and that makes everything you say invalid."

This is a murky period for Emissions and Electronic Controls, because of the way it was implemented with the GVW Break, and California having it's own set of rules.

I'm not around the GM or Mopar worlds enough, to know if there are similar issues on their pickups of the same era or not, but I would be surprised if there werent.

 

most of gm had compliance by 96, they didnt use the 99 deadline very much(if at all)
But they did use the 2004 deadline, but to lesser degree than Ford. almost entirely localized to their gmt-400 living on into the early 2000s. chassis cabs I think? That would mean its also probably only for the 454 big block which pushed into that time too

 

I was thinking about that after I answered. I remember reading that the California HD trucks were mass air but still EEC-IV, correct?

 

*That* I honestly don't know. I seem to recall that the ECM's are different, like completely different connector and everything. But there was so much confusion around this time that I could be remembering the F-150 and Bronco, and confusing it with the 250/350.

 

I read that there were EEC-IV programming on EEC-V computers and that I also have seen the computers didnt change when eec-iv

who knows
