I hear ya man. I don't know where some of the other guys found the space or what's different with their layout. I've got V&H tech support emailing me about every 10 minutes now trying to help but they can't make space where there isn't any.

 

I'm going to try and take some pics tonight...........I'll post them if a get a chance.

 

I keep seeing responses about "deeper ecm trays" but I think the problem is that on an 08 the ecm doesn't sit in a tray. At least not on a Fatboy. It is bolted to a plate which is in turn bolted to a flat part of the fender. Is this what's possible causing some of the confusion?

I'm interested in this thread because I own a 2008 Crossbones with a Fatboy rear fender and I too own a V&H fuel pack that I have not installed but did try to mock. Hard to imagine it fitting under there but we'll see.

 

I have my FuelPak installed but it's very difficult to get the seat back on due to the connectors, not the FP module. I have that tucked over to the right rear side. Many on this thread are talking about the module location and not the in-line connectors. My 08 FatBoy...no tray for the module and no place for those big connectors to lay under the seat. To put in a recessed tray would require some surgery. The stock seat has a rubber foot in the middle that sits on top of the battery when the seat is installed. The connectors have to sit to the right or left of that foot. There's no room for them in the plastic seat shell design either. We need pics of an 08 FatBoy that is claimed to be "no problem". There was at least one on this thread.

 

I hear ya. Not only are the connectors cumbersome but the wire bundles not very flexible. I'm sure there's a solution. I have to imagine that there are lots of people out there running one of these units or something similar.

 

Before I gave up on my PC-V, I toyed with the option of removing the rear fender and rerouting the factory harness behind the plastic splashguard. I could then mount the PC-V there as it has enough of a pigtail to to back to the ECM. However, given how fat the wire loom going to the connector is, I felt uncomfortable doing that. I did do just that when I installed my Badlands Illuminator R/S/B module.

 

Sorry it took a couple day to get to this, had some things that took priority last weekend.........sun was out so I rode all weekend....LOL. I took some pics of the Fuel Pak mounted on top of the EMC. I also have some of the current layout.....Running Light Module and the Alarm System Module. You can see there's not much room left over, that's why I put the Fuel Pak on top the EMC. One of the photos also shows the height of the two units stacked up.......you can also see there is no EMC tray and the pocket where they sit isn't that deep. The EMC just sits on the fender with a clamp holding it down.
I tried moving the Fuel Pak to right side where the Running Light Module sits but when I put the seat back on it wouldn't fit all the way down. I'm not sure if the low profile seats will clear the 1 3/4" stackup of the two units.

 

Thanks for the pics. What year FB did you say you had? Are you using the stock seat?

 

You will have to cut the rear fender for that to fit the deeper ECM.

 

07 Fatboy.......Stock Seat. No mods to the fender.
