The install kit for that would be almost identical to L2 kit, except it just hooks up a little differently.

I also need to add the install kits for return systems with RRP. There are so many combinations that will have a small change! But I know now what needs to be done for each, I just have to get the all the options into the drop down menu.

I can put one together for you later today? If youd like PM or email me and I can get it squared away ASAP.

Thanks
