Like I said, I'll try this tomorrow. No room to try it in the garage, so I'll take the vehicle out into the driveway.
But I'm still trying to picture this. Was your back down flat on the driver's floor in front of the seat? Doesn't seem like I (at 200 lb) would have room to get in there, and have room to move my arms up under the dashboard...
Or was your back somehow stretched over the door sill? Ouch...
Again, I don't intend to do any proxy alignment or proxy-anything-else... I'll just need to bypass the SGW in order to clear trouble codes after doing minor repairs. So I'd need to plug my Z-Automotive SGW bypass module in to do that (I don't have a 12+8 cable), and then unplug it and re-connect the cables to the SGW. I'll hopefully be able to reach up enough to do that...
