I know this is an old post but did you ever get the VSS made and if so will it work in line with the factory cable and factory gauges.....CA smog is ridiculous and I can't get it past without one. I have a 78 FJ40, 1990 350 TBI, 700R with the stock FJ transfer case. Thanks again.
I'm definitely not going to win any awards for expedient marketing but I did just get circuit boards printed. When I get home from Christmas vacation I'll be assembling the unit. I'll let you know how it goes if you're still in need & it works out.
