First the engine you are using (in your case a 3.4L) must already have provisions in the block for the crank sensor and reluctor wheel notches machined out of the crank for the crank sensor to read. The crank sensor connects directly to the ignition module via a small, seperate wiring harness (twisted pair of wires). The ignition module has 2 other plugs on it; one connects to ignition power and ground, and the other connects to the tach and computer. For wiring up the DIS coil pack to the 7730 ECM, use 1991-93 Chevy Beretta 3.1L ECM wiring diagrams; which you can download from my website.

so a 7727 and 7730 are the same thing/different case? i was at the jy confused as hell cause i couldnt find a 7730. all the cars wth the right egr were 7727s. can i go and grab a 7727 with no problems?

Here's the latest update on the EGR Adapter Plates.

I've sent the revised sample plate to DarthFiero and we'll all be waiting for his evaluation. I'm reasonably confident we should be good with the changes.

I've also shipped out 6 additional plates, to those who contacted me with address information. At this point I've used up all the extra plates I ran. Since the job is still set-up, we'll probably run some more after the holiday break and put them on the shelf for now.

Anybody has any questions or issues, PM me.

From what I've read it seems the two ECM's work the same but have slightly different pinouts. The 7727 has 4 connectors and the 7730 has 3 connectors. Anyone know where to find the 7727 pinout diagram?

I am going to use the digital EGR that came off the '95 Camaro 3.4L engine I swapped using a 7730 ECM.
