Just want to verify the wiring on this truck. The white 2nd ignition and orange hvac accessory wire are the 2 -12 gauge wires that go from the steering column to the back of the side panel fuse box and do not run to the same place as the ign,starter etc...??? The wait to start is listed as dark blue. There are 3! I tested them and still cannot tell which one is the right one. The glow light barely even blinks on this truck. It is not cold enough for it to stay on to test. Any ideas??? Set the delay for 5 seconds and forget it. I really want do do this right and use the input. I also tripped the CEL . I believe it is from disconnecting the plug on back of the instrument cluster to access the tach wire. Gonna check the codes at lunch to see what I set. Thanks

I don't use the deisel mode on duramaxes... glow lug is way fast, but if you do just do a 5 sec delay... 2nd ign is white. MUST BE HOOKED UP! org should be hvac... disconnect the bat and the cel will reset.. start with the key.. then try to rs.. sometimes it pops a glow plug malfunction... [specially if its chipped, bully dog setups pop codes with rs when installing alot!]

so the second ignition is the white wire that runs with the orange wire and goes to the side fuse panel??? I want to be sure as I read this will screw up the tranny if not connected properly. I will try the delay instead of the input as it does not get cold enough in south LA for the light to stay on longer than 2 seconds. Thanks

Yep, white running with the orange to the backside of the fuse panel.. if you didn't hook this up and tried to rs the truck thats where your cel came from.. and yes, it will mess up the tranny.... Yeah.. th wts is way to quick on them, Im in mn and havn't hadd a prob not useing itt...

no I did not try it yet as I just started wiring it yesterday afternoon tying in the power wires as I am waiting for my gmdl-bp module to be delivered tomorrow. I believe the cel light came from unplugging the gauges or from the fact that I cut,soldered and heat shrunk all of the wires instead of just tapping in as I did not want to use tape. Thanks for the info. The second ignition is the only thing that had me worried doing this myself.

Don't forget to hook up the brown accessory. It is running in the same bundle as the second ignition and orange accessory. As far as resetting the cel, Leave the ignition on, and pull the positive terminal. Leave it like this for 10 minutes, and it will reset. ------------- Northstart.....or start it your damn self.

You shouldn't need to hook up the Brown wire as a second accessory wire in this truck. It is only required on some Hummers and the Trailblazer/Envoys. If you want to use the blue wait to start light it is in cavity A2 of the instrument cluster plug. The white wire in the same plug is the tach wire. The wait to start circuit is a negative one. If you need to use a relay to convert it to a postive pulse for your remote starter, you must hook the blue wire to terminal #85 of a relay and terminal #86 to ignition (NOT Battery). Terminal #30 to a fused battery source and # 87 to your remote starter's glow plug input.

You definately do need to hook up the brown accessory. I have seen it kick codes if not done. Its especially important on duramax deisels.

I haven't hooked up the brown accessory in any of the newer gm trucks, no problems with well over 100 out there. I have been told by tech and other installers that it is not a good idea to tie directly into the wait to start wires on the newer truck 02-up. Is this valid info? I have been using the 528t pulse timer. -------------

On some of the GM trucks, both full size and smaller, you do need to hook up the Brown 2nd accessory wire. It depends on certain options in the truck. It doesn't hurt to do it and will always prevent a problem if you are unsure. It is fine to tie into the wait to start wire at the cluster on these trucks. You need to make sure that it is the correct blue wire in cavity A2. It is a negative trigger circuit. In 2002 adding a relay to invert it to a positive pulse caused problems on some trucks. You had to use a transistor to reduce the load it presented to the circuit. After that, adding a relay wasn't a problem. The other side of the relay coil had to be an ignition source though. As with anyhthing else, hooking into this wire probably got a bad rep. because some installs weren't done correctly.
