Hi,

I would be happy to help. However, we need to narrow this down. LOL Otherwise, you are going to have an overwhelming number of pics. LOL

Can you let me know if the system came with a wiring schematic? If it did, what circuits are we tapping into?

Let me know. If you want to take pics of the schematic provided by the alarm system manufacturer, that may be very helpful.

Let me know.

Okay, well, it's just a basic universal alarm I bought off of Amazon I just need to know what wires to wire the alarm to from the car. So, like the colors of my ignition wires, my tachometer wire, my door lock wires etc,. etc., you know that type of thing. lol

Hi,

I attached the wiring schematics for the entire power distribution system. I suspect that should cover what you need. If, however, something that is needed isn't listed, let me know.

Also, to make the pics readable for you, I had to cut each page in half. I did overlap them so you can follow from one to the next.

The only thing I have specific to the ignition switch is also attached. They are the last three pics which are black and white. That is how the manufacturer provides them.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below.
