One of those is a 2 pin scs connector you bridge to run ecu diagnostics
The second one I'm unsure but I don't think it does anything.

thx..
but do i need to find out what that really for? or does it matter if i just left it ? becoz i cant find any plug-in to connect those two plug

[androoz]

They are both left unconnected

[thaizeg]

^^ yea they are left as is not connected to anything. The 2 pin plug is bridged when u need to perform ecu diagnostics when u get a check engine light (CEL)

thanks heaps ^^

the 3 pin connector is called DLC data link connecor, for the diagnostics tool

Ecu-Man : So the DLC is for diagnostic tools/reader which u plug in?

[ECU-MAN]

yes, thats all it does
