wiring relation between R and parking brake?

[harryliuusa]

For a while, my Sequoia has blown fuse every time the parking brake is applied and the gear is shifted to/through R.
Is there any relationship in terms of electrical wiring?

Make an enlarged copy of the wiring diagram for your vehicle and highlight the affected circuit(s).

Get a repair manual. If you don't wish to purchase one, then try the library.
