S2000X Aux pins and D-Connector

[SpAdam]

Handful of questions regarding auxiliary connections on my G4X board.

 

CAN 1 & 2 VBATT & GND - Are these shared on the same ecu pin, or is there a dedicated 3A power circuit for each bus? 

Similar question for the other aux connectors and the 5V bus, looking at the board traces it looks like they are all connected, and that makes sense to me. Correct?

Jumpers for D-Connector - Are there any warranty concerns with making these connections? I'd like to leverage the D-connector if possible for some of my additional sensors and outputs. Is it acceptable to jump from the JST aux connectors to any of the unpopulated D-connector pins?

 

Thanks!

The VBatt on the CAN ports each have their own 3A self-resetable fuse (per connector).  Be aware however that the only 14V supply to the ecu is pin B1 so consider the total load you will be pulling through that pin/wire.  I dont know how big that factory wire is.  The ecu itself will be <0.5A, E-throttle can do ~8A, and the VTEC solenoid possibly 1A.

 There would be no issues with bridging the solder pads, just make sure there is nothing connected to those pins in the factory loom.  Any modification beyond that could potentially affect the warranty.

Copy on all of that, thanks.

Planning to add an AS connector to the side of the ecu case for the CAN, so it's just a matter of wanting a six or ten pin connector.  No current plans to power any devices off of the bus power, just trying to future proof a bit. Bonus of looming the car myself is that I know all of my ign power stuff is either 20 or 18 awg and pretty well doubled up where necessary, so I've got a decent bit of headroom

 

On the D-Connector, thanks. No factory D connector on the car/original ecu so this is just an ideal spot for auxiliary connections. Appreciate the input.
