2002 Blazer Remote Start- Starter Wire

Sorry for my late response- Vehicle is a 2002 Blazer LS (Not a TrailBlazer). I'll see if I can get them traced up to the switch tomorrow. Appreciate the help!

I hear you but I'm still concerned- some wiring diagrams I have seen have labeled the two small yellow wires as part of the VATS system.... I ordered a factory schematic from Ebay and I'm going to see if I can verify what wires are what before I risk screwing up the VATS stuff and then having to replace the BCM etc. Appreciate the help! Always best to verify the wire with a DMM. Your starter wire will show 12V when the key is in the start position and the VATS will be much less. Is this vehicle a Trailblazer or S-10 Blazer?

The best and only way you should determine the start wire is being at the ignition connector and metering voltage. 12v in the crank for a second and falls flat 0V when the vehicle starts. Solder, tape, repeat!

Interestingly enough, we aren't even allowed to use T-Taps in the UK! Need I say more or do you want an explanation. SOLDER!!

In my career I have seen countless times that t-taps have failed...melted, expanded and lost connection, and just improperly connected. Solder is faster, more reliable and permamnant. My personal preference is to do a modified western union and solder then tape. It’s how I was taught and it’s how I’ve taught my apprentices. Solder, tape, repeat lolSolder, tape, repeat!

That would make two +1's......        Soldering really is fun!Soldering is fun!

And Shark's description is exactly how I'd do it.
