I have installed an sp-400 with an int-sl module. Everything works fine except when I remote start the a/c compressor doesn't come on, the fan works and the a/c switch lites up. I also have the abs light, parking brake light, and the gas,temp, and battery guages in the dash don't work. I have connected the pink(ign), white(ign2), and the orange(acc) wires and have checked during remote start and all have power. I used a relay for brown(acc2) with no luck. Does anybody have any ideas???

sounds like one of your ing or acc wires are not getting powered up    have you checked to see if you have 12v at all the ing and acc wires when remote started ?? do they act the same using the remote start as they do with the key

are there any unused heavy gauge wires left at the ignition harness? if so, then you should test them to see what they do. who knows you might have a 3rd acc or ignition that needs to be powered up. dont trust tech sheets, trust yourself. i learned that after spending 3 days on a neon just because the tech sheet forgot to mention anything about a 2nd ignition.

Try each wire on the heavy guage to make sure it outputs the same when the key is used, as if you were to remote start it.

If not, you might have a 3rd ignition as mentioned before. But I believe the trailblazers only have those 4 wires.

they do have only pink(ign1), white(ign2), yellow(starter), orange(acc 1), Red and red w/white(12v constant), and brown(acc 2). I tested all of the small guage wires w/ no luck. I tried hooking up through relays to the ign wires thinking the alarm was not supplying enough juice through itself, and that didn't work! I am at wits end!

and this issue only occurs when R/S'ing the vehicle??  never with the key?
