Canbus wiring question!

Post by Tayleb »

Doing the 04-06 to 07-08 TSX ECU swap and had a question about CAN wiring.

I want to run the CAN Hi and Lo wires to the OBD2 port so I can read/write via flashpro, but I don’t have an open spot in the CAN junction or CANbus port.

Can I just run the CAN Hi and Lo wires straight from the ECU pins to the corresponding pins on the OBD2 port? Will that work fine or mess with anything?

Appreciate any help from anyone who’s done this before.

You can try it, but this is not recommended.
