Need Help installing a Kenne Bell Boost a Pump

[lodhammerdin]

So, when I bought the car, It already had a BAP in it but the wiring was shotty at best. The wires were striped and then just electrical taped together. I was deployed at the time when my father picked the car up from the dealer ship and told me about it and said he was going to do it right for me. So he takes the tape of and seperates the wires but didnt mark them.... and then he doent have the right connector for the wire size. So the long and the short of it is that he never reconected it and now I'm back in Ft. Hood and he is in Tucson. Can anyone help me? I will go take pics of it and post the up so that I can get some better help.

These directions are for installing the BAP with a wiring upgrade. If you don't have this upgrade, I would strongly surggest you invest in one for the reduction of duty cycle. The kits can be purchased for approx $45 from a number of SVTP vendors.

BAP and Wiring Upgrade Step-by-Step Instructions
VERIFY COLOR OF WIRE ON PLUG WITH PIN NUMBERS ON RELAY ​

1) Remove driver’s side and rear felt insulation panels from inside the truck area.

2) Decide on location in the trunk for mounting of BAP, Boost Controller, and Wiring Upgrade Adapter Plug, but do not mount them at this time. (The BAP should be located within 8" or so of the FPDM and the Adapter Plug is commonly attached to the lower mounting bolt of the FPDM. Some like to mount the Boost Controller inside the cabin, but the majority locate it in the trunk. Your choice.)

Example of Common Mounting Points for BAP, Boost Controller, & Adapter Plug ​

3) On a suitable work area, attach the ring terminal lugs to the BAP grounding wire (Black) and the Wiring Upgrade Adapter Plug grounding (Blue or White) wire (PIN 85).

4) In the same work area, solder and shrink wrap the red 30amp fused wire from the BAP to the (Black or Blue) wire from the Wiring Upgrade Adapter Plug (PIN 30).

5) To have your BAP run full time, (the most common application), take the red and black wires which are inside of the BAP’s other Black wire and solder and shrink wrap them together. This wire is approximately 16' long and you can cut this to 6-8" before soldering.

6) Disconnect negative terminal at battery.

7) In the trunk of your Terminator, disconnect the harness plug that goes into the FPDM and peel back the tape and loom on the harness for approximately 8". Locate the Green/Yellow wire in the harness and cut this wire so that you have equal length of it on both ends. (This is for attaching the BAP before the FPDM! To attach it after the FPDM, you will need to locate and cut the Brown/Pink wire.)

Fuel Pump Driver Module & Harness ​

8) Mount the BAP, Boost Controller, and Wiring Upgrade Adapter Plug to the locations you decided upon in Step #1.

9) Solder/shrink wrap the the following wires:
- Connect the (Yellow or Black) wire (PIN 86) from the Wiring Upgrade Adapter Plug to the Green/Yellow wire from the FPDM wire harness.
-Connect the Non-fused Red wire form the BAP to the Green/Yellow wire from the connector side of the FPDM..

10) Reconnect the harness plug that goes into the FPDM

11) Attach the BAP grounding wire (Black) and the Wiring Upgrade Adapter Plug grounding (Blue or White) wire (PIN 85) to the location where the FPDM is grounded.

BAP & Wiring Upgrade Grounding Location​

12) Time to run the 8 awg wire from the battery to the trunk:

-Attach the ring terminal lug to an end of the Red 8 awg wire included in your upgrade kit.

Under Hood Power Distribution Box Terminal​

-Decide on suitable location (within 12-16" of power distribution block on fuse box) for the 40 amp AGU fuse holder.

1) 40 amp AGU Fuse Holder & 2) Running theRed 8 awg wire through the firewall – Option 2 ​

-Cut the red 8 awg wire the correct length to reach the fuse holder location and attach the installed ring lug to the terminal.

-Attach the red 8 awg wire to the other side of the 40 amp AGU fuse holder.

-Mount the 40 amp AGU fuse holder in the desired location that you’ve previously selected.

-Here are different 2 procedures that can be utilized for running the red 8 awg wire through the firewall. (see above picture for Option #2)

Option 1: Using a big screwdriver, gently work the top edge of the 2" diameter rubber grommet on the firewall outwards until you have enough room to feed the red 8-awg wire through to the interior. From under the dash, carefully pull the wire through to the interior. Wrap several layers of electricians tape around the red 8-awg wires that is in contact with the firewall sheet metal for extra protection for the wire insulation. Reinstall the rubber grommet onto the firewall.

Option 2: Using a very sharp razor blade, carefully put a cut into the grommet on the topside. Be carefully not to go too deep and cut any of the factory wires. Use a metal coat hanger and tape the red 8-awg wire to it. Make sure you use enough tape so that when you pull the coat hanger from inside the car through the grommets you do not pull the coat hanger out of the tape. You can use WD-40 or a silicone spray lubricant on the grommet and electricians tape to help in this process.

-Install wire loom over all exposed 8awg wire in the engine compartment.

-Run the wire behind the driver’s side kick panel and underneath the door sill.

-Remove the rear seat by pulling it up slightly and reaching in and pressing in the two clips on either side of the transmission tunnel.

-Run the Red 8 awg into the trunk and to a location where it can be spliced with the (White or Yellow) wire from the Wiring Upgrade Adapter Plug (PIN 87). Solder and shrink wrap these two wires.

13) Use wire ties and electricians tape to secure all the wires involved in the install process.

14) Replace the 20 amp mini-fuse in Slot #14 in the fuse box under the hood (right behind the battery), with the 30 amp mini-fuse supplied with the BAP kit.

15) Reconnect negative terminal at battery.


Notes: -These directions are intended for installation of the 40 amp BAP kit which is the most commonly used for the 03/04 Cobra.

-The Red wire in the Wiring Upgrade Adapter Plug is NOT used. This is also the center plug on the relay so there is no need for it.

-The initial setting of your BAP Boost Controller can be anywhere from 25 to 30%, but to properly determine what you should set it at, you should datalog the car and pumps to indicate the proper setting for your application.

-If you would like the ability to have the BAP turn on and off based on boost pressure, eliminate Step #5 and wire the appropriate Hobbs switch to the red and black wires which are inside of the BAP black wire.

why does this thread have 10k views?

Here is a diagram that I made to help people out. I had trouble too when making my own upgrade harness so this should clear up everything.

Dam after I get no reply s in 2 days I delete my post and help comes .
The big non fused wire I wasnt sure if it when up into the wiring harrness or to the connector ?

 

[FiveOhJoe]

Yeah the 10ga. non fused red wire from the BAP goes to the green wire on the connector side of the FPDM. This is what feeds the FPDM the now-boosted signal to give the pumps more powwaaaa

thank you so much

Also heres my other issues I have a fuel pump wire upgrade for lethal while back it as the round tupe 40 amp fuse in round plastic holder..to me the wire looks to be bigger than a 8awg. Was wondering if I could use this wire coming from the fuse box with the 40 amp connector also to my 40 Amp BAP ? And just run a round 80 amp fuse up front in the holder?
Or do I need to feed another wire from the battery the to bap relay in the truck?
Thanks again

 

[FiveOhJoe]

Ideally you want to run a line directly front the battery. Nothing in the fuse box has a big enough wire to support an additional 40A of load. Actually I've been told the BAP is actually only 30A. But still.

It's fine if its bigger than 10ga. As long as its not smaller you're fine. On mine I had a 8ga going to the trunk the fed both a small 7.5A kicker sub and the BAP.

I don't understand the part about the 40a and 80a fuses. If you have a 40a up front then use a 40a in back. I don't know why they would give you an 80a fuse.

 

[FiveOhJoe]

Just read it again.....are you using the wiring upgrade kit for just the BAP? Or is it also feeding power to your pumps?

At any rate, you need a 4ga, wire to support 80 amps. I'd just run a second dedicated power wire from the battery for the BAP.

Will do thanks man

Question about this diagram shouldn’t you have 30 go to battery and 87 go to BAP fused side. The relay normally rests at 87a in the default position. When 86 gets signal power then flows from 30 to 87.

Is there a reason it’s done this way vs based on the typical relay diagram ? Just asking because I am installing one today.
