remote starter for a 2002 trailblazer

ok all of the bypasses and the model came in but i cant figure out why both of the bypasses have the same wireing harness and how to connect it all.

Did they not come with wiring diagrams ?Jeff

kinda but not good ones

The wire harnesses are universal, dont be alarmed by this it is not confusing, just cut off the smaller connector that does not get used, then install it like the diagram shows. As far as order for installing. Since this is your first time, I would spend tiem inside connecting your remote starter wires to your GMDL1 and PLDATA, cutting the unused wires shorter and taping them off so they do not confuse you during the install. The PLDATA is the last thing to install, but you can install 3 of the 4 wires at the same time you install the starter since you will already be working on a ground, power and (-) out when running. Like I said I would spend all the time you need before hand making wire connections that need to be made between the starter and the two modules since they share common needs. Read the instructions on the GMDL1 and the PLDATA and make sure you follow those. The more time you spend preparing this, the less tiem you will spend under the dash breaking your back.J Rilla
