Is tappin the wire a helpfull killer of the vp and if i have it tapped and not hook the box to it is it safe or what?

 

First off, welcome to the site.

Tapping the wire will not kill a good pump BUT if your pump already has a problem it will finish it off in a hurry.

You can tap it and just turn the box off and it makes no difference so that's not a problem at all.

But most importantly, don't tap the pump, cap it. Get a pump cover and do it right. Several places off these, but here's my preferance. Blue Chip Diesel Performance Specialists

Don't forget to fill in your signature so we know what you have for a truck. It helps us answer your questions better if we know what were dealin with. There's other things you need to do to this truck before you think about doing this pump tap.

 

I do not like pump covers. I have seen way too many issues with them including low power due to a dirty signal. In fact, I could not diagnose a low power issue with my own truck years ago with a bad cover. It appears that it had been wicking some moisture causing the slightest bit of corrosion. I gained a solid 3 MPG just by tapping the wire. That's how screwed up the cover was. It was a blue chip cover as well. In fact, I have it on the wall somewhere to this day.

The right way to pump the wire is to solder it. Everything else is just an attempt to get it close to that end. The pump covers are far better than the scotch locks, but we only solder the wire in the shop for our customers. There is no failure rate for us this way when every other method has had issues at some point.

We use a "stinger" wire with a protected quick connect. These connections are pre-tinned and use heat shrink as well. This lead is a little long in case it ever needs to be cut back for a new end. And finally, the connection gets filled with dialectic grease to guard against water entry. It also allows for use or testing of various boxes with a single install. As far as the soldered joint, it's covered in several layers of liquid sealer. This vulcanizes over the solder and the wire insulation for a waterproof seal. And this is then covered with a very small loom up to the end of the stinger wire for abrasion protection. The stinger is also zip tied to the other part of the harness for strain relief.

Doing things right takes more time and energy. But it is truly worth it in the end.

sorry for the hijack but is there a way to tap the wire on the harness

 

What is the pump wire tapping that you speak of ?

What else is needed ? Is it for a Programmer or what ?!

No hijacking indented

 

its for like an edge juice with attitude.... and has anyone ever had a vp have heavy fueling then when you let off it like goes to 0 rpm and then rev back up???

 

Tapping the wire is for boxes that add fueling to the truck via an external wire that must be tapped or connected directly to the pump harness. The pump covers do the same thing, but they rely on a sharp pin to make contact with the circuit board on top of the injection pump. Crack the board and your done.

Basically, it's the other 100 HP that the Edge Juice, Comp, Quad ADR, redline, TST, ect add tot eh truck. You can only get around 65HP through the CAN-BUS connection as the Edge EZ, Quad XZT+, ect add.
