Well, finally after I ordered my swivel base on about April 5, it has shown up. What a deal, only 35 days.
Moving on, I don't exactly see how I'm going to route the electrical wire for the seatbelt switch (which triggers an airbag light if left unhooked). I thought there would be a hole already through the center of the base to route it, but there is not. I'm not sure where would be a safe place to drill or if it's even possible.
I know many have added these, how should I do it? If I just hide an extra length of wire in the front of the base will it let me spin the seat around? This seems like the only way, and it's far from perfect.
