pigtail
mikeR, did you solder the pigtail on with the wire in place, or were you able to get that bundle out of the engine compartment to do the soldering? i have thought i could probably "hide" the pigtail in a piece of loom as you described, if i have to take it in to the dealer... ... ... . and yes, i know the ECM would "rat" on me. most techs, however, prolly won't go to the trouble to take the loom apart???? if they go that far, they're prolly gonna void my warranty for some technicality anyway... ... .

I did the solder job on the truck. I'm a 'lil guy with small enough hands, but yes it's a pain the a** job. The only way to do it off the truck is to remove the injection pump because you cannot take the pump wires off of it.
The last couple of times I went to the dealer I left everything in place. I was getting too tired and lazy to keep removing things. They weren't working on my engine anyway and all my add-on wiring looks stock complete with OEM connectors.

TAKE NOTE!
A situation arose (see thread in Truck 911 forum) where Jon (pnwradar on the TDR BB) attached the ground wire from his Edge Comp to the black ground wire on the Blue-Chip replacement VP44 pump cover. The next thing you know he finds out he killed his injection pump!!!!$
$
As I was about to hook up my black Blue-Chip wire the same way (more or less), my OE '98. 5 VP44 almost met the same demise.
The following is an Email response from Blue-Chip Diesel to my query about the black wire on the replacement pump cover:
"John,
The black wire is for our Blue box or FMS box. That is where we get ground. Use the ground that Edge wants you to use.
Jane"
In other words: DO NOT USE THE BLACK WIRE PROVIDED BY BLUE-CHIP ON THEIR REPLACEMENT PUMP COVER UNLESS YOU ARE HOOKING UP THEIR BLUE-BOX OR THEIR WIZARD FMS!

bob wagner , we would like to think that , but you know the premise behind this is to hide the nick from DC prying eyes .
where do you think DC got their info and all of a sudden trucks start having void stickers on the VP and the ecm ???
hardlined wastegate ????
bluechip tryed to go around the wire nick with their test lite , looks like DC didn't buy into it .
yes , the ECM don't lie , and i am my own warranty station ... if i get caught
, but there seems to be alot of bombing warranty questions when we all really know the answer ...
john , when i tried a bluebox on my truck i didn't connect the ground wire to the pump , i just connected it to the engine , worked fine , can't figure out the reasoning behind the bluebox , other than a possible ground loop ... weird how it burned up a VP44 , ground is ground , ain't it ???

Mopar,
When you tried the Blue Box do you remember hooking up the red wire to the pump then the black to a wire in the wiring harness going into the pump? I think Jane was wrong in calling this a 'ground' wire... it's not. The wire before the pump is a stock signal wire that BC intercepts as a reference, then modifies the signal(voltage) after the solenoid. It seems BC uses this method to know when to add more voltage(fuel). Remember the old 3-wire blue boxes do not have boost module wires for reference for power demand, so they referenced the power demand from the stock pump signal, and it seems they stayed in this practice. That's why their pump cover has two screws.
TST and Edge boxes add voltage(fuel) by what the map sensor is telling the box the power demand is, that's why the other boxes have only 1 wire hook-up.
In this case where pnwradars' pump smoked, I would think that attatching a ground wire from a box and ground the signal going to wire to the solenoid sort of back fed alot of juice into the solenoid burning it up instantly as you hit the key to start the truck.
Members who are thinking of using the new Blue Chip pump cover with any box other than a Blue Chip, please read the "Truck won't start" thread in the 911 section to avoid smoking your injection pump. Only use the pointy screw on the cover with your pump wire and attatch your ground wire to the intake manifold.

Hey Mopar-muscle, give us all a break on that "I'm my own warranty station" BS. Seems to me you removed half the accessories on your Ram before taking it in to have DC bankroll your "warranty" situation. 
PS: It's too late to take the high road now!
Ever hear of the words criminal intent?

Mike, Jon, I've been wondering if the cause of Jon's failed pump is possibly due to the red wire, or more precisely, the pointed set screw that pierces the OE pump wire beneath the replacement cover. The Blue-Chip installation instructions state that the set screw should be turned in until it just contacts the OE pump wire... you are then instructed to turn the set screw an additional 3. 5 turns (thereby piercing the wire).
What if...
the set screw was turned in too far, thereby piercing completely through the OE pump wire. This leads to the formulation of my theory... what is beneath the OE pump wire at the exact location where it is pierced by the Blue-Chip set screw? If that wire was laying on a metal portion of the pump housing... guess what, you just grounded the hot wire! That could sure ruin your day (not to mention your bank account!)
As I haven't installed my Blue-Chip replacement VP44 pump cover yet, I have no idea what is underneath the OE solenoid pump wire at the exact location the set screw pierces the wire.
... just a theory

John,
When I went up to pnw's house to tear into the truck we thouroughly checked those pierced connections. The pointy screw did not go through... all you see is copper underneath the plastic.
To risky of a chance to me, especially since it only takes a quick 5 seconds to remove an intake bolt.

boatman, I believe the reason Chip and Jane of Blue-Chip Diesel recommend using the ground location that Edge Products specifies is due to one word:
LIABILITY
What usually follows is something like:
well, it should be ok (to use the Blue-Chip, black ground wire to ground your Edge Comp) however, we can't authorize this.

i ran the 4 wire blue box , without the boost module wire connected and laid down 390ish HP with the black wire connected to a wire off my intake . the same nite i hit 397 with my hot PE . the blue lite on the box lite up like it was supposed to and it smoked like a freight train ...
no blue chip is not condoning or suggesting that people try to dupe dodge for a warranty claim , they are just supplying them with a tool to do so all in the name of making a few bucks , though it has a different purpose ultimately ...
your turn

I finally got around to installing my Blue-Chip replacement VP44 pump cover last night. The installation went pretty well.
The replacement cover is very exact on both set screw locations (which are used to "tap" the pump solenoid wire and the corresponding grounding point). PS: I removed the cover after leaving a "witness" (reference) mark with the set screws at each location. Both locations were right on the money!
..... and the shear, exhilarating power of an Edge Comp on 5x5!
:--)
what more could be said?
