  1. Wiring assistance needed

    I like it! Hidden behind the grill, lots of light, looks great! Nice work.
  2. Mach 1 HP wheels and Tires, vs. non HP

    I have a '21 non-HP. I installed 275/35-19 F and 305/35-19 R Michelin PSS and Steeda Dual rates. Really happy with it so far. Hasn't been on track yet, but 2 events scheduled for April.
  3. Broken Steering Rack on a 2022 Mach 1

    The 3 links you provided above... each shows for different wheel sizes. That would most likely point you to what package each rack is for.

    Haapy to help!! Good luck with the project...
  5. What did you do to your Mach 1 today

    info: I edited to put in my FORScan source in my other post. I'm using Livinitup's 21-23 F150 sheet. Some of the S550 stuff out there is a little older than our Machs. This is the best ref I've found for our cars.
  6. What did you do to your Mach 1 today

    When I changed the settings, the radio defaulted back to AM. I then tried selecting Sirius, and when it didnt select, I went straight back to Forscan. So I never got to test 1 & 3. Its really easy to do, just be slow and 2x check what you're doing. So try all 4 and see what ya like. For now...
  7. What did you do to your Mach 1 today

    I'm using Livinitup's 21-23 FORScan, and the ACM breakdown is for a 21-23. So perhaps this is one of the changes you mentioned for 21. I'll make an edit to my post. :) 👍
  8. What did you do to your Mach 1 today

    Played with Forscan a little after a full 8 speaker (ctr disconnected) replacement. 2021 Mach 1. 1. Wanted better sound spectrum from the new speakers. 2. Since installing new speakers, the chimes have become quite loud. Suspect due to increased efficiency of the new speakers. Had read before...
  9. 2020 GT500 map sensor pinout

    This is for a 2021. Best I can do and hope it helps.
  10. What did you do to your Mach 1 today

    Nice. Good to have a nice sounding system. I also left the rear panel un-modified. So in Forscan... I had read to disable the EQ and get fuller sound, change ACM 727-01-02 as built from 01xx-xxxx-xxxx to 00. Found later this changes radio presets. Looks like ACM 727-01-02 xxxX-xxxx-xxxx is EQ...
  11. What did you do to your Mach 1 today

    Hi Martin, I found the stock 9-speaker system to be flat, tinny, totally without bass and basically of very low quality. I usually left the radio off when driving. So thats my 1. As far as just replacing speakers, I'd give this an 8 or 9. When just replacing speakers, you could go more...
  12. What did you do to your Mach 1 today

    Replaced all stock speakers (9-system) with Infinity Reference. REF375TX 3/4" A-pillar, REF307F 3.5" coax upper doors and REF607FSL 6.5" coax lower doors and rear shelf. Disabled Ford Eq and disconnected the center speaker. Much, much better. Some of those speakers looked like the stockers out...
  13. Louvers

    Top is def better... lower looks melted and out of whack.
  14. No foglight indicator after dead battery

    Wow. Ok. I agree, flashing the BCM may NOT be a good idea then. And I dont have anymore info for you. You know, the Mach 1 does not have fog lights and there's no way to get the fog light indicator to work if you do install fog lights. I wonder if this may have something to do with your...
  15. No foglight indicator after dead battery

    No, it shouldn't. Skye's suggestion is a very good one.
  16. No foglight indicator after dead battery

    OK, not looking good. I am now suspecting you have a BCM issue. Could be that you had a voltage spike that toasted the fog light indication transistor. Of course, I dont know everything there is to know about these cars. I would take it to a dealer and allow them to investigate. Tell them: 1...
  17. No foglight indicator after dead battery

    Great! Ok, so you know the lamp (or LED) is good. Turn the headlight switch on AFTER disconnecting the battery. Turn the headlight switch off BEFORE re-connecting the battery. Fewer voltage spikes. Are those fog lights stock or aftermarket? Did the fog light indicator work for certain before...
  18. No foglight indicator after dead battery

    Its possible. There's no telling what the logic really is that can create a reset. But... :wink: The headlight switch works by supplying grounds of individual circuits to the BCM. When the BCM sees that particular ground, it energizes that particular circuit according to its programming. So...
  19. No foglight indicator after dead battery

    @Le Mans The fog lights are all powered by the BCM. BCM is controlled by the fog switch on the headlight switch panel by supplying grounds. According to OP, this all works fine, front & rear. There is no schematic nor fuse for this single indication in the instrument cluster. It uses one of...
  20. Custom fog light install

    Those are great lights and will work well. I just didn't feel good with the appearance of them in the M1 grill. There's a company making a kit for these in the M1, and the appearance just doesn't make me happy. Nothing wrong with em, just not the look I want. Still need to work on alignment on...
