Default SAP location with M52 swap?

I just took possession of a 1996 ti with a 328 engine from a '96 vert. My brother owns a shop and did the work. Neither of us can figure out where to install the secondary air pump since there's not much space after the swap. We did a complete key/ECU swap, so the car thinks it's a 328 vert.

1 - Where did others install the donor SAP in the ti with this swap? The CEL is on and I'd like to figure this out.

2 - Or, is there a thread with pics to build a SAP simulator? The other thread is detailed but the pics are all defunct.

3 - Or, perhaps there's a way to flash Z3 Euro firmware instead? There's a thread on that, but I didn't see a way to install the 2.8L firmware.

1) Battery to the hatch and install the SAP where it would be in a 328.

2) SAP simulator, you can buy them already made or make one yourself. e36-electronic.com

3. Swap tune can turn off anything you don't want turned on. I went with markert motorworks and have been very happy with their tune, lots of other great tuners out there too.

Thanks for the advice. I'll look into the simulator option first!
