Thermactor System

[Bronk351]

Well my motor is out of my bronco, due to me trying to use it as a submarine. Well anyways, im planning on cleanin her up. I got rid of the EGR a couple of months ago by using the Eliminator from RJM injection, and i made my own blockoff plate. Well with me having no cats, the thermactor system is pretty much useless, i even had one of the hoses undone from the air pump.

So from this point i know i need to plug the back of the heads with some pipe plugs, and copper RTV, but what do i do with the vacuum lines? I know i need to disconnect em but what ones do i disconnect? Anyone ever do this, or have any idea what ones. I wanna make sure i dont take the wrong ones off. Thanks for the help

& Ryan's EGR Removal Instructions

notably; "...Disconnect EGR Valve Position sensor (EVP), and inspect the harness connector. Make

sure it

So after reading posts here I have done some mods. Removed smog pump. Short belted. Removed EGR and plumbing. Installed block off plate and eliminator from RJM. Capped vacuum ports. Capped and plugged exhauts holes {RJM plugs}. AirAid throttle body spacer. Next is the exhaust system.

Its is showing a check engine light and I have yet to get the code.

Since I made that reply; Ryan wrote elsewhere,

When performing computer Self-Test after installing this kit it is normal to get code:

33 / 332 EGR valve opening not detected.

The computer is acknowledging that the EGR is permanently closed. This is your desired

result. However if you get the following codes:

31 / 327 - EVP circuit failed below the closed EGR limit of 0.24 volts

32 / 328 - EVP circuit failed below the closed EGR limit of 0.24 volts

34 / 334 - EVP circuit failed above the closed EGR limit of 0.67 volts

35 / 337 - EVP circuit failed above the open EGR limit of 4.81 volts

Code 33/332 is the desired result, if the light still comes on:

Check your connection again; make sure there is no resistance in the harness.

or you'll need the $300-$500 chip. Or just live with the light!
