Becker 780 security wiring diagram, need to bypass

I bought a becker to replace the one I have now from pullapart. It was just as bad the one I had so today I went back and exchanged it. The new one is the from a 300 and has an anti theft circuit, wired into the iginition I believe. At any rate when plugged in it just clicks. Anyone have the pinout for the anti theft circuit so I can just disable it?

Yeah, don't plug in the five pin harness. Problem solved.

OH. I guess there is another problem then. When I hit the power button I hear a relay just click over and over again. I assumed the 5 pin harness would close a circuit?

No, the harness is for the alarm only. I ran my 780 in the SDL (yes I know it came with a 754 stock) without that harness hooked up. I swapped the Becker as the FM tuner was crap.
