remote starter 2001 silverado

ok since I have done maybe 50 of these trucks i'll try and shed some light on your starter delima... Take the shroud that surounds the dash radio and stuff off... it just releases by clips... then there are 2 7mm screws below to take off the knee pannel... takes those out... then there is a metal bracket type protector thing being held in with 4 10 mm nuts take those off exposing the main ignition harness of the truck... In this harness you will find some small wires maybe 16 gauge and some wires of a bit more size maybe 12 gauge the smaller wires your looking for are a orange wire with a black stripe... and a yellow wire side by side or fairly close to each other these are your passlock wires... How you test for them is by taking off some of the jacket of both wires but not letting them touch and taking your digital multi meter and putting the black probe into the ORANGE / black wire and red probe into the yellow wire... Once you put the key in the ignition you should read anywhere between 4ish volts up to maybe 5.5 volts... when you start the vehicl with the key the voltage should change and you should have a steady reading of anywhere between .5ish volts to 4.5ish volts... try this about 3 times (start and shut off with the key) to make sure the voltage isn't jumping around but everytime it should be the same maybe .001 off... any other questions just ask... i'm not too familiar with the starter your installing but I can sure try and help you with wire location! good luck!!
