Dear friends, what are the main differences between this model and model obdii protocol detector & break out box diagnosed obd obd2 connector | warran

Just looked at the obdII protocol detector & breakout box. Looks like the two are basically the same thing. I would say the otc piece is probably a little better quality piece, of course it costs a little more money. But the two will function pretty much the same way.

Does it come with Jumper wire in the kit?

yes it comes with two jumper wires, one is a switched normaly open wire and the other wire is a solid wire. both jumpers have 4mm unshrouded male banana jack adaptors.
