I need to reset or replace the SRS control unit. In the repair manual it says to unplug both seat belt tensioner connectors and both seat belt buckle tensioner connectors before unplugging the 3 main connectors at the control unit.

1) Is this really necessary, or is it overkill? Is there really a risk if I don't disconnect all 4 tensioners at their base before disconnecting the main harness connectors at the control unit? Seems kind of redundant to disconnect the same harness at both ends just to replace the box on one end... I don't really feel like removing all that trim along the floor and B pillars if I don't have to.

2) Also, any thoughts on whether it's safe/reliable to have a SRS unit reset (after airbag deployment) versus buying a new one from the dealership? I've seen a few services online such as myairbags.com and safetyrestore.com. I called a few body shops around town to ask their thoughts, and answers were all over the board - from "yes all the time" with 1 shop (although their reset co. is local and only deals w/body shops so I'm out of luck), to "never hear of that", and everything in between. Myairbags.com states they've been around since 2006, and I've seen them mentioned on different websites here & there, so maybe they're legit? I can't help but think in the back of my mind "will airbags deploy again in the event they're needed, with a reset box?". It seems like it's a simple enough process, so there shouldn't be too much to worry about in theory, but I'm not sure. You send them the unit, they do the reset (clear the hard codes stored in it) and send it back, all for around $60 - versus $400 from dealer + reprogramming.

Thanks for any input!
