Hi all,
I have been doing heaps of research re OBD2 and I keep coming across conflicting information.
For example; using software from obd-2.com, some people say you can hook your laptop directly to your OBD2 connector under the dash using a simple serial cable (found this on this board on a thread) while others say you need a piece of hardware in-between to convert 5v from the laptop to 12v on the truck.
From my searching on the Internet, I found pin connections to connect a DB9 connector on the back of a laptop to an ISO OBD2 connector. The pin connections are:
Laptop (DB9) (Truck) ISO 16 Pin D Type Connector
1-----------------------5
2-----------------------4
3-----------------------6
4-----------------------7
5-----------------------14
6-----------------------10
7-----------------------2
8-----------------------15
9-----------------------16
Using these connections, I can rig up a serial cable in 1/2 hour, however I was wondering if anyone has actually done something like this or do I need to get a piece of hardware as some people state.
The reason I'm asking is that I don't want to fry anything
Cheers and TIA
Erron
