Read the about on that page. Vetronix was bought by Bosch years ago. Thats simply a website selling knockoffs using the name
Thanks, good to know. I have an original through GM a long time ago but I needed a Candi and some adapters and got them from one of those sites, it works fine.
Almost every car I do with it needs a Candi and need security access and all that but as Cline said not for some (if not all, I don't know) GM trucks.
Any idea when Bosch bought out Vertronix?
