Welcome to TVT. Frankly, I didn't answer sooner because this has been hashed over sssssssssssssoooooooooo many times already. There is a search feature in the upper right corner of each forum page. You can also use Google or similar site to search (just add the term "toyotavantech" to your other terms). Here's a link to an article on our home page:
http://www.toyotavantech.com/forum/c...vice-Connector. Near the end of this article there's a link to specific information for your year of van (tells what each code means). If these articles don't point you in the right direction, get familiar with the search feature and this should help a lot. If searching the site doesn't point you in the right direction, find a similar thread and ask your questions there. This helps keep future searches simple. Tim
