Anybody know what the 5th pin the connector does? I can't seem to get the engine to spit anything out on 1708/1587 (its got the bosch controller). I see that there is a special V-MAC II cable that nexiq sells for $200 that is nothing more that 6-pin to 6-pin, any idea what its doing inside the cable?
Mack 6-pin diagnostics.
