No, but I do have one from a 68rfe and I can flash in a clean Aisin file with EFI Live, for the cost of the license + the ECM.

Before I jump the gun, here, I need to get back to the house and see if my file is an 07 or 08.

I WILL CONSIDER YOUR CORE ECM(S) IN TRADE!
 
Is C1 the injector/engine controls, or the power/transmission side of the ecm? I forget. :(
How many pins is the connector plug between the 2 harnesses, I know the manual trans has fewer than the auto and the plug isn't as wide.

I believe I have the trans/power side to spare.

C1 is indeed injector/engine control harness

It's the harness closest to you if standing in front of the truck
 
How many TOTAL cavities are in your plug that joins the 2 together?
Not WIRES, but cavities or pin positions available.

I'm about 99% positive that the spare half I have is the power/trans side.

I have a complete 2008 set here, C1 and C2, but I don't really want to break it up, it's a nice harness.

I also have a pile of other harnesses at the house, I'll look and see if I have the one you need in that, maybe I missed one. :bang

LOL, I have a hard enough time parting out a couple trucks. Not sure how you keep track of 100's of trucks. You must have great organizational skills:Cheer:
