LS3 eRod ODB2 Port
I want to wire up an ODB2 port on my Nova with an LS3 eRod engine and controller. The engine controller bulkhead connector has the following pinouts.
Pin Description
A -- GMLAN High Speed (-)
B -- Brown/White MIL
C -- Engine Speed
D -- Vehicle Speed - Out
E -- MAP Signal - F - Plug Empty
G -- GMLAN Low Speed (+)
H -- Oil Pressure Signal
J -- Throttle Pos #2 (0.5v - 4.5v)
K -- battery Power Fuse
L -- Ignition "OnPower
M -- Ground
I have part of the connector figured out.
ODB Pin Bulkhead Pin Description
16 -- K -- battery power
4 -- M -- Ground
5 -- M -- Ground
1 -- G -- GMLAN low speed
Is this all I need and are the ODB2 pins correct? Do I need GMLAN high speed and should ODB pin 4 go to the chassis ground?
