Remote Start - 98 Sierra

Hey all...    This is my first time installing a remote starter. I have a 1998 GMC Sierra 6cyl Auto.    I have read the instructions over and over. I think I have it down but was just wondering if anyone had any extra tips.    The kit I'm installing is a Jensen JKRS3    I have the wiring diagram for the truck and it looks like all the wires are right under the dash. I think I'll be using the under hood light for the safety.

Inhibit wire on 98 Sierra. - White brake light switch wire. Might anyone know if it's +12v or -12v? Thanks!

12 volt - (negative)

Goes to + (positive) when pedal is pushed

Have everything connected except two wires: 1) Starter wire, still trying to decide between two yellow wires which one is correct. 2) Tach wire. I found the following info for a 2001 GMC; would this be the same for a 1998? (6cyl) "...take out the 4 phillips head screws that hold the instrument cluster in, tilt it forward and pull it out. Find the only white wire (99% sure the only one) and that will work perfect..." I did what it said and found a white wire but dont have a DMM to test it with, just a light. I didn't test it yet though. What do you guys think?

There is a yellow wire and a yellow jacketed airbag harness, STAY AWAY FROM THIS HARNESS!>! the yellow wire you want was taped in with the rest of the ign wires. There will also be a small 20awg yellow wire which is the Rcode wire for the passlock systemShaughn Murley

I would suggest buying a multimeter. I wouldnt be doing this stuff without one. Even if this is the only one you do I am sure you will find other uses for the meter in the future.  A cheap one will do. Somewhere around $20

Heh. Just read your post. Guess what I just picked up from Radio Shack! A new DMM. I had to get one because I made all the connections but I can't get the unit to program. The default settings are fine but the unit requires that I program the Tach before it will remotely start. I followed the instructions but it doesn't seem to be working. Here are the instructions:    a) turn key on    b) press program switch 3 times    c) turn key off    d) hold down program switch and start car using key    e) wait for lights to flash 3 times then release sw. ...but the lights never flash 3 times. I know the lights flash (keyless entry is working) I measured the Tach at the unit, it's at about 3. I tested the program sw using DMM, it's working. I know I'm missing something but I dont know what.

Does your TACH measurement (with meter) increase when U REV up the engine?MO
