I'll find out on Saturday... and let you know. I *think* that it will be possible to mount it in the vicinity of the OEM ECU, but have yet to try it. It will require some sort of custom mounting system for sure. I need to confirm that there is enough room as the MS box is maybe twice as thick as the oem unit?
Cheers-JB

I tried installing this weekend: car would not start. The ECU was communicating with the laptop, but it just cranked with no hint of trying to fire up. Trouble shooting to follow. Jumping the fuel pump is the next step, but it will probably be a while before I have time to attack this project again.
Regarding mounting in a '99: you MIGHT MAYBE be able to mount in the stock location, but it will TIGHT. The problem is that the harness uses those two big connectors that are themselves very tall, add to that the stiff cable that sticks out from those and it's just so cramped with the pedals and other wires that are already populating the area. I think I'm going to have cut Rev's harness and extend it as well ala JeffMan. I just don't see how it's possible to install without doing that.

These connectors have provisions for side exiting of the wires, if that helps.
I've very interested in any solution that doesn't require hacking up the PnP adapter harness. The one I build is ~20" long, which is long enough to wrap around the MS.

I'll have to play with harness and see what I can do. It's just so tight in there because of the pedals. The OEM unit is inbetween the brake and clutch pedals. Your ECU is 2 - 2.5 times thicker than the OEM, space is limited out of the box. Maybe I can work on the side exit and see if the wires can come over the top of the unit. If I can do that it might work. As for the box, I think you can probably zip tie it to the stock brackets.

It's tight, but my MFSII(tm) fit in two different spots.
Right of the steering column, harness points towards heater vent
Left of the clutch pedal, harness towards firewall
Once zip tied in place it would not rub against the pedal as shown in the picture.
Overall length was ~260mm
If you relocate the relays there would be tons of room

[QUOTE=nismo240;855164]Is group buy still open? Interested in a MS for 99-00. What is the price shipped to US-MA? Would like to mount in the glove box and do an easy connector swap for OBD2 testing once a year.[/QUOTE
The group buy is over. Spend some time reading over the first few pages of this thread, then go to the MS section of the forum and do MORE reading.
