I'm still skimming through and yes it's a good book! I'd like it even if your truck was not in it!

Melding of the 0411 minds in here, lol! Might have to add that into my collection.

With all this collective knowledge, any input on Tow/Haulass integration on a 97? Single switch and what PCM Pin? Any way to add a light?

With the 0411 swap you can easily add T/H mode. There is no indicator light for T/H mode on the GMT400 truck. You give a single PCM pin a MOMENTARY Ground to engage T/H. If you press the button again or cycle the key, T/H is cancelled.

Well its not GMT400 its a GMT600 but I think it should work the same way. Did the indicator light work off serial data or is it a pcm output?

The Body Control Module turned on the light in the cluster. I have never looked into how it is turned on.

I bought the book the other day, lots of good info inside!

also, might be able to use the "shift light" output to control the t/h light.

Who is Lextech, and what the heck is a 411 PCM? Does that PCM give you some sort of information display?





Lextech's truck is killer, exactly setup the way I would want it, the S60 top it off.

I always wondered about simply cycling the key, momentary ground switch out of a GMT360 (Trailblazer should work, or the T/H button out of an earlier Blazer.
