Be aware that you will be communicating with the ECU from here on out, and that brings with it certain risks. READ You might stuff your ECU, especially when programming. I am not responsible for any damage resulting from customizing or programming the ECU and any modifications will be at your own risk. Right, now that weve got that out of the way, lets get to it. Modification. There is this locktab on the OBD plug that prevents the cable from being pulled off accidentily once plugged in. Heres what Im talking about Normally the cable should come off with a firm pull, but I think the tab is either too stiff, or it has some manufacturing imperfections. This causes the plug to get stuck and refuses to come off. To solve this, do one of either two things remove the tab completely remove some material from the inside of the tab with a utility knife to make it more flexible. Even with the tab removed as I have done, it is still firmly enough in place that there is no concern of it coming off on its own. Installation. The small disc supplied with the cable contained all the necessary to get started. If not, it can be downloaded from UOBD2, on the technical service tab from the sales link. It is worth mentioning though that the suppliers of this cable used a kill one bird with 1. Not everything supplied on the disc is necessary, but its there in case of installation problems.
