Also when you get the injectors back please ensure you use new o-rings and grommets, as previously referenced. In the photo from post #110 four of the the six injectors do not have the grommets on the engine side so they are probably still in place - ensure they are pulled
As for your wiring harness if it looks good and you are getting voltage, within spec per the FSM, I would wrap as others have said but I would also add some heat shield, I used a product from DEI called heat sheath, in the EGR area to add another layer of protection before securing away from the the EGR.
