Aside from the bracket that attaches it to the manifold, is the egr vacuum solenoid for a TPI the same as one for a TBI? They both appear to be very similar with exception to the bracket. If so I could save myself a few bucks on my TPI swap.

 

They are functionally identical. As long as you can mount it, it will work the same.

 

That's good to hear. I went over the wiring diagrams in my factory service manual and even the wire colors are the same albeit reversed. I figure I could snip the connector off my TBI harness and splice it into my TPI harness and just match the colors. Is the IAC valve the same as well? I looked at them up close and the TPI valve seems to have a slightly larger cone and the opening for the cone in the TB is also slightly larger as well. The wiring is identical though.
