Removing ABS, Retain LSPV

[AppleTech]

I'm planning to remove my ABS on my trail-only truck. I'd like to retain the LSPV as I don't have any issues with mine and it seems necessary to retain some of the failsafe dual-circuit functionality of the brake system.

My question is regarding the rerouting of brake lines in the engine bay. There 4 lines:
1 Goes to FR brake
1 Goes to FL brake
2 Goes to rear/LSPV

The way it appears now is that the two outputs from the MC go to the following

FRONT OUTPUT: ABS rear circuit -> LSPV
REAR OUTPUT: Tee -> ABS front circuit and LSPV

So how should I hook up the MC with the ABS system removed to ensure proper LSPV and redundancy? My guess is this but I don't know for sure:

FRONT Output: rear circuit/LSPV
REAR Output: To tee where one side goes to rear circuit/LSPV and other side to another tee to two front lines?

Do a quick search - there’s a few threads on here detailing abs removal that have all the information you need.

Well the issue is that all of them also remove the LSPV, which I don't want to do. I haven't come across one yet that keeps it...

Although the more I read the more it seems like I should just remove the valve. I don't load my truck up enough to really cause any need for it...

The system exists for the opposite reason. The light(er) rear end needs more brake force to even out the stopping effort. Without a load leveling valve, the front brakes do all the work. If you have an equivalent load in the cargo area, the LSBPV does nothing.

This is why there's a load balancing requirement in the FSM.

If you're planning on using the truck for off-roading, the valve is really unnecessary.

It seems reasonable to assume that the lighter the rear axle is the easier the brakes will lock therefor the lspv would actually allow more braking power to the rear as the cargo load increases and the suspension compresses.

Removing the LSBPV does not compromise the dual circuit nature of the factory system. One output of the master cylinder goes to the rear, the other goes to the front.

Baldilocks has it right. The rear brake hydraulic pressure is dialed back when there is no load, and increased when the suspension is compressed from a load.
