'69 P/U brake controller connection help

[Christianad1156]

I've hit a dead end and can use some help.

I'm wiring in brake controller into my 1969 Chevy K20. I don't want to splice or cut into the wire coming out of the brake light switch.

Does anybody make a connector that goes in between the two-pin connector on the wiring harness and the two pins on the brake light switch that effectively splices the wire for the brake light signal? An extra wire would have to be provided that I can use to connect the brake controller wire/harness.

The two wires I'm talking on the harness are the white and orange wires on the two-pin connector. I'd like to minimize the "modifications" to the electrical system as much as possible. I've looked for a while for this product on the message boards and various sites.

If not, how has everyone else connected the brake signal wire?

Let me know if the question doesn't make sense please.

Thanks in advance!
