PIWIS 2 cable pinouts

Recommended Posts



I have a Bosch KTS650 cloned as a PIWIS (1), which was working great until loaned out to a local friend to delve into a problem he had on his 997 which had a delayed start problem (that I posted about last year on here)..


Unfortunately, when the unit came back, it was without the main OBDII lead!!


So I have some questions for the collective here who may know..


1 - Is there a difference between the KTS650 and KTS520 connectors and pinouts for the OBDII cable.

2 - Is there a difference between the correct PIWIS OBDII cable and the Bosch KTS Versions and clones?

3 - Does anyone here have a pinout for a standard Bosch KTS650 or KTS520 OBDII Cable?

4 - Does anyone here have a pinout for a PIWIS cable?


I know with the PST2 that I have, there is an important few differences between the standard KTS cable and the PST2 Cable, which an awesome member of this site helped me with before.. So before I go making up a new lead (I have just ordered the connector and a 16 way OBDII open ended cable with connector) I will need some pinouts...


I have found a place in Germany who is selling a KTS520 cable, which they say works on a PIWIS based on a KTS520, but I am not sure if it will be missing features, or if it will even be right on a KTS650 based PIWIS clone... In particular I experiment with control unit programming and reverse engineering, so I really could do with it being the right lead, so I do not end up chasing my tail with programming errors like I did with the PST2 until I found out I did not have a complete lead.. However, any lead which semi works will be better than no lead at all!


Please help!!! Its is pretty useless without the cable!
