So to continue on…
Not sure how many knew this but my truck originally had dual alternators from the factory. Now the way the ECM is setup it randomly selects which alternator to use to charge the system each time the truck is started. That means you CANNOT simply unplug the second alternator and go on, because should you do that and the ECM selects the alternator that is no longer there, the truck will drain the batteries and leave you stranded.
All that said there is a simple work around.
On the passenger side fender well there is a harness that the factory dual alternator plugs into. When you remove the second ALT the harness needs to come out too.
It plugs in right here.
Those of you who don't have a second ALT will see a little "loop back plug" in the end of the harness. This is what you need to replicate with the factory dual ALT harness.
It's very simple.
Remove the old harness and find the plug that looks like this.
I had already modified this one before I took this pic. But the green loop back is what you need to worry about. You have to change the pin out locations for the green wire and remove the others.
To do that you need to take and pull the rubber stop out so you can access the release pin.
I used a piece of 1/16" tungsten to push it out.
Once you have removed the red tab, proceed to remove the other wires and pins and put the two green pins in the location you see here, then button it back up and plug it into the factory harness along the fender well and you are DONE.
I only had to do this because I have decided to use fire hoses for injectors and needed a twin pump setup and the way they mount to the head you can't utilize a dual ALT.
Next up was building the pedestal for the high pressure turbo.
Had to decide how I wanted to orient it in the valley. I wanted to build mine similar to Oliver's with the LP in the valley but the LP I used is entirely too big to do so without a completely custom intake manifold. So I proceeded to mock up my HP mount.
Pedestal built and HP mounted. Simple yet effective.
Next up was the up pipes.
Forgot to add this earlier.
I have had a BPD kit installed for a long time now and decided to go with their race plate for this build as it allowed me a multitude of options for routing coolant and oil to the chargers and twin pump. Plus it was super low profile and would work perfectly for this build.
Next was plumbing in the wastegate.
Next was the LP mount and intermediate hot side pipe.
Then it was time to start mocking up the cold side piping.
Cold side piping all welded up with the exception of the hot CAC pipe. As that needed to wait until the kit was in the truck to determine final routing due to the degas bottle.
Next it was time to weld it all up and get it all wrapped.
I chose to soak my wrap in a glue and water mixture to forego the wire ties.
Here it is all dry and cured.
Next up is install.
