Unfortunately we are going to pull the plug and cancel the project. We have been so busy this year (best year to date) that there has been zero time to even look at it again. Also the company we were working with was shut down due to covid and are backed up on their normal stuff so it would delayed months more on there end.

 

What a bummer.

 

Mind me asking who was the company you were working with if one of us poor souls stuck effing with the platform might have the opportunity to pick up the torch? I tuned a half dozen 98 cars in the last month

 

The fact that a mfg can make something like this (top link) and make a profit but not make a red and blue male 80 pin connector (bottom link) and make a profit is a greater bummer. They can mfg the female red and blue female connectors but for some reason don't want to mfg male red and blue 80 pin connectors.

With two red and blue male connectors one could make a bridge harness where it would be plug and play. Plug the 98 harness plug end into the male bridge harness and then plug the opposing female end into the 411 pcm.

With access to male connectors one could easily make a short bridge harness at your kitchen table, compared to struggling to do it in your garage stooped over 160 wires in your engine bay.

 

I was about to ask the same question

 

They are in the same boat we are....super busy and dont have the time to work on it. At the time they were a little slow and had most of the stuff to make what we wanted. Its just not worth the time and cost vs the return on it. Unfortunately its not going to happen any longer. I would recommend piggy backing a terminator x as a better option.


It was going to be plug in play but there is more involved in it, due to almost all the wires moving locations and changing plugs.

 

If someone was handy w/ a mill they could make some male connectors.

 

This is what I think would be the easiest build yourself if male Delphi 40 pin PCM connectors were available. The female Delphi PCM connector and housing is readily available. I have been unable to find a Delphi equivalent male connector that would mate to the female Delphi connector.

Am thinking this will be a winter project.

When finished the harness would like the Ford Extension harness in link below.

Basically what I had in mind. A quick drawing to give a visual.

 

The stock 98 harness plug ends are female and plug into male receptacles on the PCM. So the adapter harness plug ends need to female plug ends that connect to the PCM.

The PCM contains male pins. See link.

There are female plug ends on the stock harness. What is NOT available is a kit like below that contains male pins. See link below.

If you were to repin the existing harness IMO it would be easier to buy the kit above and reassign the wires into connectors in the kit than to try to use the existing harness female ends.

However, IMO still easier to build an extension harness that contains four 40 pin male connector plug ends. Either way you only reassign the pins on the PCM side of the extension harness.

 

if you are abandoning the project anyway, it would be pretty interesting for the community if you just open sourced what you figured out so far.

 

2 bar resolution for me was the principal reason to make the switch to a 411 pcm.

IMO with a 98 PCM it's not necessary anymore to convert to a 411 pcm if you plan to run forced induction (2 bar). I simply upgraded to the 2 bar HPTuners Custom OS instead. The custom OS contains additional tables for boost (the primary 2 bar VE table with much better resolution, plus some other tables for example).

 

Yes but you dont have access to flex fuel like you do with the 99-up stuff, or 3 bar map

 

Agree - the HP Custom OS isn't for everyone or for three bar. I don't ever plan to convert to flex fuel or run the dragstrip so the custom 2 bar OS works for me.

I have a source who thinks he night be able to do a conversion adapter - but with covid issues past year and half with the company he works for he doesn't have the time. Seems no one want to come back to work. As a result lots of overtime for those who do leaving little time off with his family.

 

Did anyone ever figure out a male connector for this?

 

I pretty much quit searching after installing the HP Custom OS onto the 98 pcm. With a D1 Procharger I don't ever plan to run anything but gas. The extra tables in the custom os was all I needed to get a decent tune. The 98 tables didn't have enough resolution.

 

Its a real problem for a lot of folks, worse as the 98 PCMs dry up or stop working, I have helped a couple people redo their existing harness like I did with used ebay plugs, that may be the only way youre going to have success, the plugs are usually around 20 bucks a set, a soldering iron, a couple hours, and a lot of patience will go a long way if you already have the 411.

Just took a drive today and its still working perfectly.

Good luck either way, if they have removed the diagram for the changeover from this forum, let me know somewhere I have it printed out and I can send it your way.

 

Did anything become of this?

 

Haven't seen anything

 

I might be interested in one..
