2001 chevy silverado 1500 base model/pyth

Got the 555L module in yesterday late and will install today will post results, should work no problem-reading the directions the resistance wire is Yellow and the Ground wire is ORANGE / Black on the Pickups and SUVs.

OK, there are two yellow wires at the BCM, Which one?

Is it the yellow wire located (counting pins like on the python alarm) at Pin 2? Next to the Pin 4 ORANGE / black wire?

Follow it up towards the ignition cylinder.  The three Passlock2 wires should be grouped together. 

Soldering is fun!

Man I tried to follow it/them, but it runs into a taped up loom and goes towards the firewall and into a larger harness and gets real complicated from there, so much so I'd have to destroy a lot of looming and I'm not sure about doing that. I got a link to a page on the12volt.com https://www.the12volt.com/installbay/forum_posts.asp?tid=63567

Try opening up the steering column ( drop the lower half ) and locate the Passlock2 wires there, where they originate, at the ignition cylinder. 

Soldering is fun!

Well, I found the ignition cylinder and found the wires but I suppose I should not complain but there is not much wire to work with before they go into a bolted plug/harness, just not much wire at all, well, just figured that out, I can lengthen them all. So Thank You very much again! Looks like its going to work out after all and today too!

I'll get to it in few, just woke up and have got to be alert more, when I start.

OK, so far so good, it cranked up with a key.

Al right!  

 Make sure all the connections are well soldered and insulated.  Neaten up & secure all the wires.  Test it a few more times and then button it up.

Soldering is fun!
