HELP! Looks like one of the contacts broke in my column ignition cylinder last night and the dreaded 'SECURITY' light came on and no crank. I have looked into the Vats bypass resister trick and came across a module made by Override Motorsports. They are on ebay, but when I googled them, they show closed permanently in Michigan, but the ebay listing shows an Arizona shipping address.

Anyone dealt with them before?

Why not have it programmed out of your memcal ?
or http://www.bakerelectronix.com/products_vats/
If this is on your 91 the hz signal goes to pin f10 a blue wire at the ecm.

I am an electronic ignoramus when it comes to these things, so your last sentence might as well have been in Greek! This is a daily driver that I need rolling pronto, and I can't get it to someone to reprogram the ECU if I can't start it. Do you know how the Baker unit installs?

As fast as I know the baker one has a 3 wire hookup. Frequency a blue wire to the ecm. A accessory power and ground.
this one might work too

You can use a6 as a power for the module and any one marked ground.

AAAAND... wouldn't you know it, the damn thing fired right up tonight!! I thought I would 'give it one more shot'- you know, what we all do when we go out to start these 30 year old cars in the morning(!) and it turned over like a horny old lady! The day I had this issue, the ignition key pulled out of the ignition while the engine was running, with no problems- the engine kept running- so I put it back in and parked it. That's when I had issues on restart- anyone have this problem or experience something similar?? I am stumped, but I am still going to bypass this damn VATS!!!

That’s odd, but glad it started back up.
this is one way to bypass it, just read the description it has emissions deleted.

If the vats wire in the column breaks it is close enough to sometimes still make contact. Just install a new ignition tumbler with the vats wire and new key and all will be fixed. No need to bypass if fixed correctly.
