06 engine harness question

[cdslguy]

Is the engine harness the same on a manual shift 06 truck as an auto 06 truck?

 

[cdslguy]

looking to swap ecm and harness along with valve cover, rocker box, etc on my 05 to an 06 to run efi live. I have a harness but not sure which one I have or if there's a difference. My truck is a stick truck.

the engine side in C one in both manual and automatics are the same c2 is different though if I remember rightsee one is the one that goes to your injectors and your cam and crank sensor and coolant temp sensor and oil pressure sensor in the 06 and probably a couple others I'm forgetting

Thank you. I guess I will need to figure out which harness i have.

The harnesses are different. If you see a bunch of yellow and green, you likely have an auto harness.

Thanks!

Yeah you'll need the stick harness. The manual harness uses the VSS differently from the auto.

I don't think it matters, my buddy swapped his auto to a 6spd in his 06 and he told his turner and they made new tunes and theirs no lights on and it runs great
