I just put mine in too the vacuum line where my stock boost gauge hooked up at
And if you still want to use your stock boost gauge you can buy a little t and small piece of vacuum

Harley's don't have factory boost gauges.

Ok, when I get the chance I'll post a pic of where you want the gauge to tap in to measure boost. If the set up didn't come with vac hoses, then you will need to buy a vac hose about 5ft should be more than enough I think.

Have you wired everything already? Or do you need to know where to mount sensor etc.?

Sight unseen I'm not sure if your application requires rubber vacuum/boost line or if you need the clear nylon boost tube used to install a mechanical vacuum/boost gauge. Regardless, both can be purchased at your local auto parts store.

For images of the nylon boost line do a google search for "Auto Meter 3223." This is the part number for Auto Meter's clear nylon boost line which come with some ferrules for install.

Rubber vacuum line and various t-fittings, y-fitting, etc. are cheap.

For the gauge to function properly you need to tie into a vacuum/boost reference. I recommend using the vacuum/boost reference for the fuel pressure regulator (FPR). Look on the driver side fuel rail, you will find the FPR. Tap into that line for your gauge. To route the line to the gauge you can pass through the large rubber grommet located on the firewall next to the brake booster, this is the easiest place pass through the firewall.

No, I haven't wired anything except the gauge
