96 EK1 OBD2 location?

[Willo]

So from what I have found one is a Service Connector and the other is a Data Link Connector???

I'm still none the wiser, why there is two. I can only assume one is for checking the ECU service codes and the other is to program the ECU???

Is there a way to get a bit more out of the ECU?

no,

DLC is for Honda HDS or PGMFI tester, you can also get aftermarket readers that connect to the 3 pin DLC

the SCS is only for reading codes and setting the ignition timing

sorry to dig this up but are there any conversion plug to turn these 3 pin DLC and 2 pin SCS into OBD port ??
