Hey i was looking at the install on the APEXi V-AFC and it talks about the VTM wire.. what exactly is it.. and does the p13's have them? Im just curious because it says some models do not have them.
Hook it up. I never found out what it was either, even from Apex, but I was throwing a CEL, and vtec was cut out at a certian point, once I hooked it up, all was right.
