urgent!!!

Good, I need if please someone knows how to bridge the ECU of the Geo Tracker or Chevrolet Tracker to get the fault codes. In these vehicles, two kinds of connectors are: 6 and 4 pins I think. please give me a little hand ..... thanks !!!

WTO to help you need the complete data, year, displacement and the rest. thank you

The year of this in Parical is 99, but I would like to know for the two types of pins, no vehicle data is necessary to know how to bridge, the year or the displacement does not solve my question, I would appreciate if someone has knowledge there are only two pins regardless of the year.
Thanks WTO

WTO, here we try to help it is not a way to answer the one you put, anyway the year if it is important since the OBD II takes has a Face feed that if you get to tap with a current can cause damage, now you will need the boys table you already have it?, anyway the well -prepared workshops have a scanner that can help you if you want you, you take it. As data put on Google how to tap pins and the model and will take you to a page I don't remember its name, greetings.

I almost forget it, the displacement is used to discriminate the injection system used, to be able to differentiate from AFI, multitec, ti, mpi, etc. Chevrolet has equal codes in several models but do not have the same determinant so Saverlo will be helpful.
