Changing car over to race in 24 hrs of LeMons. removed ARC module and then hacked off the wiring to module.(then tossed it all in the trash) Now Speedo quit working. I dont need to know how fast the car is going, tach works, but does the car need to know?(ECM or other system?) Seems to be running OK but my tech guy thought maybe after a while w/ no speedo input the ecm might have issues. Any thoughts, recomendations?
Thanks, chuck donley
 
I recently removed the ABS module, along with the ride control module and restraint module as I wasn't transplanting these to my F100 street rod.

I started clipping wires systematically back to where they appeared at their respective connectors. Let me tell you, there were not many wires left to the rear of the truck when I got through. However, there were quite a few ground wires which I tried to leave as-is.

End result, check engine lights but no lost functions like speedo.
