switching from an 03 pedal to an 07 shouldnt be an issue as the pcm pins are the same correct?

i believe so let me double check on the PCM are the same

Ask Your Own Dodge Question

We have different pin out between 03 and 07 unfortunately

Ask Your Own Dodge Question
Customer reply replied 1 month ago
yeah i understand that but look at the apps if there swapped then it should be ok

6 pins vs 8 pins

we do have 2 pins duplicated but they have different wires colors

if you connect the 6 pins to 6 pins and leaves the ect 2 what happens

Ask Your Own Dodge Question
Customer reply replied 1 month ago
no difference no pedal hooked it up shows correct circuit numbers think the different colors are for manual/auto applications?

why not rebuild the COMPUTER THAT IS IN IT AND GO BACK TO ORIGINAL

A LOT ONLINE COMPANIES YOU MAIL OUT AND COME BACK TO YOU PLUG AN PLAY ,NO PROGRAMING NEEDED

yeah i understand that but look at the apps if there swapped then it should be ok

we have 4 different 5 volt supply based on your file ,u sent me ,which wires are you using for 5 volts ?

you need to try every combination possible ,if they all have power ,,

unless the computer bad

that is the only thing i can think off

Customer reply replied 1 month ago

Ask Your Own Dodge Question
Customer reply replied 1 month ago
