TPI EGR Removal

I have an 87 Formula 305 TPI.
I am considering switching my MAF setup to Speed Density and would like to disable egr on my new prom. Just wondering if anyone here knows the procedure for removal, as I am very unfamiliar with how egr works. Questions I have are about removal, as in where to hack off parts, what to plug and with what, and what is the hose just lower of my radiator cap going to. Heater core? Looks like someone spliced mine along the way. If anyone has info or suggestions, let me know.

Use a block off plate where the EGR valve goes.

Plug any other access or vacuum lines for it.

U must delete it in the prom to get it to actually completely quit working. It affects other things when "on" other than just exhaust gas back into the engine.

See the DIY PROM board here for complete turn off procedures.
