OS3B or GMAHLANB with Steering Wheel - Tip

hey guys, i found something out the hard way.  

if you are using a os3b or a gmahlanb to power a screen,  the first thing you need to do is read the bulletins.  pac and peripheral have bulletins out concerning their plugs that mate with the factory wiring.  you must jump around the plug for constant +, ground, and the data signal.  also, don't run the power through the module for your screen's power.  hook on where you are jumping around.  these modules don't do well when you run a lot of current through them.

also, if you are powering anything else, you  must, must ,must get your power and ground from somewhere other than the radio harness.  i suggest going to the battery or the fuse box and using a relay.
