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

All GMC vehicles have a (+) brake wire.

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 system

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?

yes, tach increases when the RPM's go up.

Just so it's out there this is how I tested it.

Using a DMM; connected +lead to a +12v power source and touched the -lead to the Tach wire on the remote start unit.

tach is at the PCM on the drivers fenderwell, white wire in the plag labeled white.

Well. I've emailed Jensen (audiovox)to let them know that the programming will not respond. I hope they can help me resolve this issue as I am lost. Maybe it's just a defective item.

I ran a search and found one post where the tech had a similar issue and it turned out to be a dud unit and had to be swapped out. Has anyone else had a similar experience with Jensen or Audiovox/Prestige?
