The guy I bought my 92 gt from removed most of the vac. lines and pluged the water line that runs to the front of the throtle body. He put rubber covers on the nipples in front and back of the throtle body. The line in the front obviously goes to the front nipple but I can not find the line for the back. Do I have to put a T on the line to the heater core or the a/c hose from the firewall? Im not sure where it needs to go. Also what they exactly do. I cant seem to find it in my Chiltons Manual.
PLEASE HELP!!!!
Thanks!!!

I want to measure mine. It doesn't look that tall.

there should be another nipple on the heater pipe for that hose. Leave it off. unless you are driving in sub freezing temps there is no need for that water line to be there.

All that does is circulate hot coolant through the egr spacer and INCREASE the temp of the incoming air

you're better off to leave it off

The lines are there to cool down the plenum from the heat of the EGR, not for de-icing. The EGR gasses are factors hotter than coolant temps. Cobras and 94-95's do not have these coolant lines because the EGR design was changed.

This pic might help.

Good luck.

If your erg is functional, hook them back up.

Sorry, that's something I should have mentioned. If your EGR system is still functional (from what you've said it sounds like it's probably been deleted) then you need to hook it up. The coolant lines help cool down the plenum due to the additional heat that te EGR system is adding. If your EGR is not hooked up, it will actually increase the temp.
