Electrical switch installed and the no-start issue with the key is GONE.
Something to be happy about.
Happy dance.
It wasn't a fun job. To be sure it wasn't the alarm relay or any alarm component before I spliced in the new switch I tested it. Works as it should with or without the alarm attached. Carefully removing the splices/taps etc.. was no fun.
I was just about to put all the stuff back together but as the sun was going down I started getting attacked by multiple sand/horse flies (garage open) so I quit. Fun fun.
