The right insite

[Chamberpains]

Inline 5 adapter will work and you'll need at least Insite version 7.6.2 with service pack 5. Most of those ebay buys are fine and come with all the hardware and software. Although the service pack 5 or SP5 usually isn't with the chinese knock offs. SP5 update I know corrected a problem with being able to cut out multiple single injectors during an injector cut out test. So you'll probably want that or track it down. Its just an update to 7.6.2
