Default Vats Bypass Module Help

http://www.3rdbrakeflasher.com/docum...odule_2017.pdf

just purchased the bypass module but I don’t understand the instructions. I have a 94 lt1 so I know it’s 50hertz. The blue and green wires I do not need, but where would I put the red, black and white wire into?

Red goes to any 12V source that is powered when the ignition is on(you could run it the fuse box "accy")
Black goes to any Ground
White goes to pin 25 on the PCM RED connector(PCM is located on passenger side under hood by the firewall)

Is there a reason you didn't go with the resistor route? Assuming that the problem is the contacts in the cylinder lock.....

Has your BCM failed?

how would I connect it to pin 25? Do I have to cut the wire then connect to it?

the previous owner added a starter solenoid I guess since the vats we’re giving problems. I want to remove all of that and just bypass vats completely

So when connecting wires can I cut it and run a 3 way splitter on it?

Why not hit a pick and pull. Grab the pigtail from a wrecked or dead 4th gen from under the steering column. Wire in the resistors to match, plug it in and forget about it. Probably cost less than $5 total. Can reverse anytime you want put you probably won't.

So, just bypass the theft deterrent relay completely and be done. Just cross yellow to purple.
