Colorado Accessory, doorlock issues ?

I did an '05 Colorado, following the advice and diagrams for using a 555L etc. Got the car to start, but the Accessories would not turn on, I ended up pulsing the 555L off for 1 sec. after start, and they woke up. Also found lock/unlock as a light blue and white at BCM. Any one have insight as to my mistakes ? Thanks in advance, and Happy Holidays ! Steve

I am not familiar with the 555l, but if those trucks don't see the correct starter and Passlock sequence during remote start, the heater won't come on even though there is power on the WHITE/ red accessory wire. Check to make sure your bypass is designed for the 05 Colorado. Most bypasses aren't. You must wire them the same as a Saturn ION.sparky
