Where does the egr bypass cap go? I don't see any plugs on the passenger side that would plug into the Z1 egr bypass cap

Closer to the middle rear of engine seen in pic linked below for the egr temp sensor. Find the egr temp sensor and follow wiring to connector.

ok, that is not what I was looking at. Are the oxygen sensors actually in the exhaust manifolds. I think the O2 sensor us what I was looking at

thanks for the help. Will have to relook. We passed on pulling the egr so we cut back the pipes. We had actually discussed crimping and folding back the pipes. Is the egr vacuum hose on the passenger side? There is a small solenoid or something with 2 hoses on the pass side on a small bracket

Yes the egr vac hose leads towards the pass side. Look at the pic in the link, you can see the diaphram has a vac hose connected (right edge of pic, about 3/4 down)

SO found the EGR connection for the bypass cap. Pipes have been cut back. Tried smashing them close but no way with pliers abd tried a C-clamp but clamp just won't stay put to work. Going to cap them.
