I understand and for that reason I'll test it first, my hope is there is some truth about the product that It'll do as promised. Failing that i will get it done professionally. I just begrudge paying for something i could do myself.
I've bought some in the past but never had any luck connecting them to the airbag connection. Thinking the issue was because i've been using generic units I've decided to buy one specific to the MR2. Problem i have is the connection is the same but in the image for the side airbag there's a yellow connector
