Popular Post TimberJack Posted October 16, 2017 Popular Post Share Posted October 16, 2017 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. 3 Quote Link to comment Share on other sites More sharing options...
880joe Posted October 16, 2017 Share Posted October 16, 2017 Did you change front engine cover so that the ac compressor was on the left side And did you have to change anything else Quote Link to comment Share on other sites More sharing options...
TimberJack Posted October 17, 2017 Author Share Posted October 17, 2017 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. Quote Link to comment Share on other sites More sharing options...

TimberJack Posted October 17, 2017 Author Share Posted October 17, 2017 The only difference I seen on the harness was the AC harness had two more pin in the plug. Quote Link to comment Share on other sites More sharing options...
2000CL713 Posted October 17, 2017 Share Posted October 17, 2017 That's good info to know. Be nice to buy a newer truck with the newer cab (inside) and swap everything out of my 2000 CL and into a 2004 if I wanted to. Hmmmm Quote Link to comment Share on other sites More sharing options...
KKRT Posted October 17, 2017 Share Posted October 17, 2017 Timberjack, Do you have pictures of how the 2003 harness plugs into the firewall? Or is does is just plug into the old slot for 2004 harness. Great info for 2004 CH ASET owners who may consider ETECH swap, backdating, etc. Quote Link to comment Share on other sites More sharing options...
KKRT Posted October 17, 2017 Share Posted October 17, 2017 Timberjack, A full documentation of the process, pictures, etc. will help the community (especially in the wiring and ECU department). Many have struggled with the ASET, and as these ASET trucks age and/or need engines, all in the community will benefit from the knowledge on installing earlier E7s to keep our trucks rolling. Other forums do such educational topic all the time: I will like to encourage any others with additional info, expertise to please chime in. Thanks in advance.

TimberJack Posted October 19, 2017 Author Share Posted October 19, 2017 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. Quote Link to comment Share on other sites More sharing options...
KKRT Posted October 23, 2017 Share Posted October 23, 2017 TimberJack, Any update on pulling a load (power)? Plus anyone has idea an what to do to clear the lightening bolt, and the 1-4 code? Quote Link to comment Share on other sites More sharing options...
TimberJack Posted November 4, 2017 Author Share Posted November 4, 2017 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? Quote Link to comment Share on other sites More sharing options...

Did a great job, someone said the E7 has a Ambient air temp sensor but where is it located at? The ambient are temp sensor is located on the front cross member on drivers side. Its a green sensor in front of the radiator. This option can be turned off by a reflash from a dealership Edited November 4, 2017 by Mackpro Quote Link to comment Share on other sites More sharing options...
TimberJack Posted November 5, 2017 Author Share Posted November 5, 2017 I wonder if I can get one from a parts store? Does anyone know the part number for a Ambient air temp sensor Quote Link to comment Share on other sites More sharing options...
TimberJack Posted November 7, 2017 Author Share Posted November 7, 2017 Ran the truck all day and had a code come up 6-7 power relay. What is this? Quote Link to comment Share on other sites More sharing options...
