@TurboQueef Any chance you have a manual page you could reference for this so I don't muck it up on my car? I have the whole mechanical part done. Doing the wiring now, glad someone else has posted "recently". I would have been done alot sooner if I had a damn garage. It's a pain relying on weekends and cooperative weather. However, I did do some additional items in the process.

Get into the wiring. I just finished mine this past year on an 04 FXT. I bought the iWire plugs to finish it completely with the auto harness but didn't end up using them because I was able to source a manual harness, ECU, ABS module etc. I still have the plugs/wiring if you're interested in it at all. You can reuse/rewire some of your auto harness to make it work as well. Run through this thread again, it'll likely be more clear when you get into reading along and looking at the actual condition on the car.

I do know, switching to the full manual harness, I also needed to swap the ABS module. I wouldn't expect that to be an issue if you're still using the auto harness, and as someone else pointed out, splicing out one specific wire.

That said, I was also able to get mine to work with the auto harness, temp wiring and test drive it before swapping to manual. Somewhere along the way I lost my cruise control. It activates from the dash, but doesn't work otherwise.

Basically, yes. I only offer the wire harness stuff to make it a cleaner install. I don't need it, if you're interested shoot me a PM and we can discuss further. shipping and a few bucks for time/burden is all I'd be looking for.

Also note, keeping the auto harness and ECU, you may still want to get a tune to allow for the idle speed to be a bit higher than it would be with an actual manual harness/ECU. People often end up having problems with the car stalling out rolling to a stop.
