Made some progress on the water/meth injection. My wiring harness uses 7 wires, so rather than build an extension, i bought 7 wire trailer harness:
More OEM wedgelok pins being put to use
Original harness on the frame:
...and the new extension plugged in and looking OEM
The harness runs up the bed here. Next to it is a hydraulic hose connected to some 3/8 stainless tube via some swagelok fittings for the water.
The route up the bed:
Another OEM connector, where my extension harness ends in the toolbox. In the top left you can see where the tubing enters the box. 100% stainless tube from the bed hinge to the toolbox.
The original toolbox harness modified with a mating wedgelok connector installed:
...and the whole water/meth system is now reinstalled and done!
I turned the system on to check for errors and didnt find any, so i removed/cleaned the injector and then purged the system. Holy shit i think were done!!! I still need to find a place to relocate my CB antenna to, but aside from that she's 100% done!
After sitting for 7 weeks under a black walnut tree the truck needs to go to the carwash pretty badly, so i guess thatll be my test drive to see how badly the bed rattles around.
The kit comes with these guides to keep the front of the bed aligned with the cab, but i never installed them because my hinges are so much more sturdy than the ones that came with the kit, and the bed doesnt flop around like it woudve with their hinges. So we'll see after the test drive (hopefully tomorrow) if i need to put them on or not.
