  2. 2000 CL E7-427 upgrades

    I’ve been seeing some guy running the stage 2 injectors with a turbo off a 60 series Detroit.
  3. AC 427 swap to E7 427

    Ran the truck all day and had a code come up 6-7 power relay. What is this?
  4. AC 427 swap to E7 427

    I wonder if I can get one from a parts store? Does anyone know the part number for a Ambient air temp sensor
  5. AC 427 swap to E7 427

    We’ll finally got to pull a load with truck yesterday. Did a great job, someone said the E7 has a Ambient air temp sensor but where is it located at?
  6. AC 427 swap to E7 427

    The plug on the firewall for the engine harness is the same. The Aset harness only had two more pin in the plug. I did use the transmission harness that went with the Etech. I did not touch any thing in the dash just plugged the Etech harness in. The lightning bolt on the dash is on and it’s a 1-4 code ambient air temp sensor with the E7 doesn’t have. I haven’t pulled a load with it yet, plan on it this weekend. I will take some pictures and post for y’all.

    The only difference I seen on the harness was the AC harness had two more pin in the plug.
  8. AC 427 swap to E7 427

    Nope I used the lines off my wrecked 2003. The AC motor had a electric fan and the E7 was air but it works fine. I did have to use fan shroud off the 03.
  9. AC 427 swap to E7 427

    Well finished up the motor swap on my 2004 ch today. The engine harness on the 2003 E7 plugged right in the firewall, did not change out any of the wiring in dash just wanted to see if it would run. Believe it or not the truck fired right up and ran great the lighting bolt on the dash is on showing a code 1-4 Ambient Air Temp Sensor with the truck doesn’t have anymore.
  10. AC 427 swap to E7 427

    Ok I will check it out. The AC motor has been nothing but trouble since day one. So I figured what the hell the E7 only has 49,000 miles on rebuild and was a good running truck. Gone to pull both in the shop side by side and start disassemble.
  11. AC 427 swap to E7 427

    Taking E7 motor out of my wrecked 2003 CH and dropping it in my 2004 which has a AC motor. How much work am I looking at swapping the wiring harness? The AC engine has electric fan an the E7 has air.
  12. 2008 MP8 want start

    Turn the switch an nothing but a click. I replaced starter relay and no change. So I go to Mack an pick up new starter. Get the starter on and still nothing. I checked the two wires that come down beside transmission and they were good. I only have power to one of them when the key is turned all the way to the start position. Any tips would be great.
  13. Fault code

    Ok thanks it started showing the pp387 and the pp327
  14. Good and Bad Years for Mack's
