Default ABS Delete Speedo Question

I have upgraded my brakes and want to delete my abs module as I have a LS swap with stand alone computer I have upgraded brakes and having a hard time bleeding the ABS I plan to install a proportioning valve and a delete block.

Here is where I need help understanding how does this abs module read the speedo I don't understand what this braking module would have anything to do with the speed of the car There must be a way to bypass the switch into thinking this abs module is still hooked up???

Anyone that understands this connection and could lend any knowledge on how this system reads speed please post comments. If it's just a fail safe that it must be working in order to read speed then there should be a bypass

I would really like my speedo to work any suggestion
Thanks in advance

I know for a fact the speedo reads off the rear stubshafts.

pchoi did an ABS delete as you describes, no idea if his speedo still works

Read a few people disconnected the ABS module and do not have a working speedo. Have not confirmed for myself . If that's the case , I bet connecting a pair or wires, with possibly a resistor may be needed.

I thought ABS was connected to VSLD not speedo...

No, the VLSD is inside the pumpkin - not related to ABS/TCS/VDC). The ABS is a 4-channel system, and it derives each wheel's speed signal from a toothed hub on each corner of the car (on the stub axles at the rear, and the wheel bearing hubs at the front).
